GtkWidget is the base class all widgets in GTK+ derive from. It manages the widget lifecycle, states and style.
GTK+ uses a height-for-width (and width-for-height) geometry management system. Height-for-width means that a widget can change how much vertical space it needs, depending on the amount of horizontal space that it is given (and similar for width-for-height). The most common example is a label that reflows to fill up the available width, wraps to fewer lines, and therefore needs less height.
Height-for-width geometry management is implemented in GTK+ by way of five virtual methods:
WidgetClass
.get_request_mode
()WidgetClass
.get_preferred_width
()WidgetClass
.get_preferred_height
()WidgetClass
.get_preferred_height_for_width
()WidgetClass
.get_preferred_width_for_height
()WidgetClass
.get_preferred_height_and_baseline_for_width
()
There are some important things to keep in mind when implementing height-for-width and when using it in container implementations.
The geometry management system will query a widget hierarchy in
only one orientation at a time. When widgets are initially queried
for their minimum sizes it is generally done in two initial passes
in the SizeRequestMode
chosen by the toplevel.
For example, when queried in the normal
SizeRequestModeHeightForWidth
mode:
First, the default minimum and natural width for each widget
in the interface will be computed using widgetGetPreferredWidth
.
Because the preferred widths for each container depend on the preferred
widths of their children, this information propagates up the hierarchy,
and finally a minimum and natural width is determined for the entire
toplevel. Next, the toplevel will use the minimum width to query for the
minimum height contextual to that width using
widgetGetPreferredHeightForWidth
, which will also be a highly
recursive operation. The minimum height for the minimum width is normally
used to set the minimum size constraint on the toplevel
(unless windowSetGeometryHints
is explicitly used instead).
After the toplevel window has initially requested its size in both
dimensions it can go on to allocate itself a reasonable size (or a size
previously specified with windowSetDefaultSize
). During the
recursive allocation process it’s important to note that request cycles
will be recursively executed while container widgets allocate their children.
Each container widget, once allocated a size, will go on to first share the
space in one orientation among its children and then request each child's
height for its target allocated width or its width for allocated height,
depending. In this way a Widget
will typically be requested its size
a number of times before actually being allocated a size. The size a
widget is finally allocated can of course differ from the size it has
requested. For this reason, Widget
caches a small number of results
to avoid re-querying for the same sizes in one allocation cycle.
See [GtkContainer’s geometry management section][container-geometry-management] to learn more about how height-for-width allocations are performed by container widgets.
If a widget does move content around to intelligently use up the
allocated size then it must support the request in both
GtkSizeRequestModes
even if the widget in question only
trades sizes in a single orientation.
For instance, a Label
that does height-for-width word wrapping
will not expect to have WidgetClass
.get_preferred_height
() called
because that call is specific to a width-for-height request. In this
case the label must return the height required for its own minimum
possible width. By following this rule any widget that handles
height-for-width or width-for-height requests will always be allocated
at least enough space to fit its own content.
Here are some examples of how a SizeRequestModeHeightForWidth
widget
generally deals with width-for-height requests, for WidgetClass
.get_preferred_height
()
it will do:
C code
static void foo_widget_get_preferred_height (GtkWidget *widget, gint *min_height, gint *nat_height) { if (i_am_in_height_for_width_mode) { gint min_width, nat_width; GTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget, &min_width, &nat_width); GTK_WIDGET_GET_CLASS (widget)->get_preferred_height_for_width (widget, min_width, min_height, nat_height); } else { ... some widgets do both. For instance, if a GtkLabel is rotated to 90 degrees it will return the minimum and natural height for the rotated label here. } }
And in WidgetClass
.get_preferred_width_for_height
() it will simply return
the minimum and natural width:
C code
static void foo_widget_get_preferred_width_for_height (GtkWidget *widget, gint for_height, gint *min_width, gint *nat_width) { if (i_am_in_height_for_width_mode) { GTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget, min_width, nat_width); } else { ... again if a widget is sometimes operating in width-for-height mode (like a rotated GtkLabel) it can go ahead and do its real width for height calculation here. } }
Often a widget needs to get its own request during size request or allocation. For example, when computing height it may need to also compute width. Or when deciding how to use an allocation, the widget may need to know its natural size. In these cases, the widget should be careful to call its virtual methods directly, like this:
C code
GTK_WIDGET_GET_CLASS(widget)->get_preferred_width (widget, &min, &natural);
It will not work to use the wrapper functions, such as
widgetGetPreferredWidth
inside your own size request
implementation. These return a request adjusted by SizeGroup
and by the WidgetClass
.adjust_size_request
() virtual method. If a
widget used the wrappers inside its virtual method implementations,
then the adjustments (such as widget margins) would be applied
twice. GTK+ therefore does not allow this and will warn if you try
to do it.
Of course if you are getting the size request for
another widget, such as a child of a
container, you must use the wrapper APIs.
Otherwise, you would not properly consider widget margins,
SizeGroup
, and so forth.
Since 3.10 GTK+ also supports baseline vertical alignment of widgets. This
means that widgets are positioned such that the typographical baseline of
widgets in the same row are aligned. This happens if a widget supports baselines,
has a vertical alignment of AlignBaseline
, and is inside a container
that supports baselines and has a natural “row” that it aligns to the baseline,
or a baseline assigned to it by the grandparent.
Baseline alignment support for a widget is done by the WidgetClass
.get_preferred_height_and_baseline_for_width
()
virtual function. It allows you to report a baseline in combination with the
minimum and natural height. If there is no baseline you can return -1 to indicate
this. The default implementation of this virtual function calls into the
WidgetClass
.get_preferred_height
() and WidgetClass
.get_preferred_height_for_width
(),
so if baselines are not supported it doesn’t need to be implemented.
If a widget ends up baseline aligned it will be allocated all the space in the parent
as if it was AlignFill
, but the selected baseline can be found via widgetGetAllocatedBaseline
.
If this has a value other than -1 you need to align the widget such that the baseline
appears at the position.
Style Properties
Widget
introduces “style
properties” - these are basically object properties that are stored
not on the object, but in the style object associated to the widget. Style
properties are set in [resource files][gtk3-Resource-Files].
This mechanism is used for configuring such things as the location of the
scrollbar arrows through the theme, giving theme authors more control over the
look of applications without the need to write a theme engine in C.
Use widgetClassInstallStyleProperty
to install style properties for
a widget class, widgetClassFindStyleProperty
or
widgetClassListStyleProperties
to get information about existing
style properties and widgetStyleGetProperty
, gtk_widget_style_get()
or
gtk_widget_style_get_valist()
to obtain the value of a style property.
GtkWidget as GtkBuildable
The GtkWidget implementation of the GtkBuildable interface supports a custom <accelerator> element, which has attributes named ”key”, ”modifiers” and ”signal” and allows to specify accelerators.
An example of a UI definition fragment specifying an accelerator: > >class="GtkButton" > key="q" modifiers="GDK_CONTROL_MASK" signal="clicked"/ >/object
In addition to accelerators, GtkWidget also support a custom <accessible>
element, which supports actions and relations. Properties on the accessible
implementation of an object can be set by accessing the internal child
“accessible” of a Widget
.
An example of a UI definition fragment specifying an accessible: > >class="GtkLabel" id="label1"/ > name="label"I am a Label for a Button/property >/object >class="GtkButton" id="button1" > accessibility > action_name="click" translatable="yes"Click the button./action > target="label1" type="labelled-by"/ > /accessibility > internal-child="accessible" > class="AtkObject" id="a11y-button1" > name="accessible-name"Clickable Button/property > /object > /child >/object
Finally, GtkWidget allows style information such as style classes to be associated with widgets, using the custom <style> element: > >class="GtkButton" id="button1" > style > name="my-special-button-class"/ > name="dark-button"/ > /style >/object
GtkWidget exposes some facilities to automate the procedure
of creating composite widgets using Builder
interface description
language.
To create composite widgets with Builder
XML, one must associate
the interface description with the widget class at class initialization
time using widgetClassSetTemplate
.
The interface description semantics expected in composite template descriptions
is slightly different from regular Builder
XML.
Unlike regular interface descriptions, widgetClassSetTemplate
will
expect a <template> tag as a direct child of the toplevel <interface>
tag. The <template> tag must specify the “class” attribute which must be
the type name of the widget. Optionally, the “parent” attribute may be
specified to specify the direct parent type of the widget type, this is
ignored by the GtkBuilder but required for Glade to introspect what kind
of properties and internal children exist for a given type when the actual
type does not exist.
The XML which is contained inside the <template> tag behaves as if it were
added to the <object> tag defining widget
itself. You may set properties
on widget
by inserting <property> tags into the <template> tag, and also
add <child> tags to add children and extend widget
in the normal way you
would with <object> tags.
Additionally, <object> tags can also be added before and after the initial <template> tag in the normal way, allowing one to define auxiliary objects which might be referenced by other widgets declared as children of the <template> tag.
An example of a GtkBuilder Template Definition: > >interface > class="FooWidget" parent="GtkBox" > name="orientation"GTK_ORIENTATION_HORIZONTAL/property > name="spacing"4/property > child > class="GtkButton" id="hello_button" > name="label"Hello World/property > name="clicked" handler="hello_button_clicked" object="FooWidget" swapped="yes"/ > /object > /child > child > class="GtkButton" id="goodbye_button" > name="label"Goodbye World/property > /object > /child > /template >/interface
Typically, you'll place the template fragment into a file that is
bundled with your project, using Resource
. In order to load the
template, you need to call widgetClassSetTemplateFromResource
from the class initialization of your Widget
type:
C code
static void foo_widget_class_init (FooWidgetClass *klass) { // ... gtk_widget_class_set_template_from_resource (GTK_WIDGET_CLASS (klass), "/com/example/ui/foowidget.ui"); }
You will also need to call widgetInitTemplate
from the instance
initialization function:
C code
static void foo_widget_init (FooWidget *self) { // ... gtk_widget_init_template (GTK_WIDGET (self)); }
You can access widgets defined in the template using the
widgetGetTemplateChild
function, but you will typically declare
a pointer in the instance private data structure of your type using the same
name as the widget in the template definition, and call
gtk_widget_class_bind_template_child_private()
with that name, e.g.
C code
typedef struct { GtkWidget *hello_button; GtkWidget *goodbye_button; } FooWidgetPrivate; G_DEFINE_TYPE_WITH_PRIVATE (FooWidget, foo_widget, GTK_TYPE_BOX) static void foo_widget_class_init (FooWidgetClass *klass) { // ... gtk_widget_class_set_template_from_resource (GTK_WIDGET_CLASS (klass), "/com/example/ui/foowidget.ui"); gtk_widget_class_bind_template_child_private (GTK_WIDGET_CLASS (klass), FooWidget, hello_button); gtk_widget_class_bind_template_child_private (GTK_WIDGET_CLASS (klass), FooWidget, goodbye_button); } static void foo_widget_init (FooWidget *widget) { }
You can also use gtk_widget_class_bind_template_callback()
to connect a signal
callback defined in the template with a function visible in the scope of the
class, e.g.
C code
// the signal handler has the instance and user data swapped // because of the swapped="yes" attribute in the template XML static void hello_button_clicked (FooWidget *self, GtkButton *button) { g_print ("Hello, world!\n"); } static void foo_widget_class_init (FooWidgetClass *klass) { // ... gtk_widget_class_set_template_from_resource (GTK_WIDGET_CLASS (klass), "/com/example/ui/foowidget.ui"); gtk_widget_class_bind_template_callback (GTK_WIDGET_CLASS (klass), hello_button_clicked); }

Methods
Overloaded methods
activate
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
For widgets that can be “activated” (buttons, menu items, etc.)
this function activates them. Activation is what happens when you
press Enter on a widget during key navigation. If widget
isn't
activatable, the function returns False
.
addAccelerator
:: (HasCallStack, MonadIO m, IsWidget a, IsAccelGroup b) | |
=> a |
|
-> Text |
|
-> b |
|
-> Word32 |
|
-> [ModifierType] |
|
-> [AccelFlags] |
|
-> m () |
Installs an accelerator for this widget
in accelGroup
that causes
accelSignal
to be emitted if the accelerator is activated.
The accelGroup
needs to be added to the widget’s toplevel via
windowAddAccelGroup
, and the signal must be of type SignalFlagsAction
.
Accelerators added through this function are not user changeable during
runtime. If you want to support accelerators that can be changed by the
user, use accelMapAddEntry
and widgetSetAccelPath
or
menuItemSetAccelPath
instead.
addDeviceEvents
widgetAddDeviceEvents Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsDevice b) | |
=> a |
|
-> b |
|
-> [EventMask] |
|
-> m () |
Adds the device events in the bitfield events
to the event mask for
widget
. See widgetSetDeviceEvents
for details.
Since: 3.0
addEvents
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> [EventMask] |
|
-> m () |
Adds the events in the bitfield events
to the event mask for
widget
. See widgetSetEvents
and the
[input handling overview][event-masks] for details.
addMnemonicLabel
widgetAddMnemonicLabel Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsWidget b) | |
=> a |
|
-> b |
|
-> m () |
Adds a widget to the list of mnemonic labels for
this widget. (See widgetListMnemonicLabels
). Note the
list of mnemonic labels for the widget is cleared when the
widget is destroyed, so the caller must make sure to update
its internal state at this point as well, by using a connection
to the destroy signal or a weak notifier.
Since: 2.4
addTickCallback
widgetAddTickCallback Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> TickCallback |
|
-> m Word32 | Returns: an id for the connection of this callback. Remove the callback
by passing it to |
Queues an animation frame update and adds a callback to be called
before each frame. Until the tick callback is removed, it will be
called frequently (usually at the frame rate of the output device
or as quickly as the application can be repainted, whichever is
slower). For this reason, is most suitable for handling graphics
that change every frame or every few frames. The tick callback does
not automatically imply a relayout or repaint. If you want a
repaint or relayout, and aren’t changing widget properties that
would trigger that (for example, changing the text of a Label
),
then you will have to call widgetQueueResize
or
widgetQueueDrawArea
yourself.
frameClockGetFrameTime
should generally be used for timing
continuous animations and
frameTimingsGetPredictedPresentationTime
if you are
trying to display isolated frames at particular times.
This is a more convenient alternative to connecting directly to the
update signal of FrameClock
, since you don't
have to worry about when a FrameClock
is assigned to a widget.
Since: 3.8
canActivateAccel
widgetCanActivateAccel Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Word32 |
|
-> m Bool | Returns: |
Determines whether an accelerator that activates the signal
identified by signalId
can currently be activated.
This is done by emitting the canActivateAccel
signal on widget
; if the signal isn’t overridden by a
handler or in a derived widget, then the default check is
that the widget must be sensitive, and the widget and all
its ancestors mapped.
Since: 2.4
childFocus
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> DirectionType |
|
-> m Bool | Returns: |
This function is used by custom widget implementations; if you're
writing an app, you’d use widgetGrabFocus
to move the focus
to a particular widget, and containerSetFocusChain
to
change the focus tab order. So you may want to investigate those
functions instead.
widgetChildFocus
is called by containers as the user moves
around the window using keyboard shortcuts. direction
indicates
what kind of motion is taking place (up, down, left, right, tab
forward, tab backward). widgetChildFocus
emits the
focus signal; widgets override the default handler
for this signal in order to implement appropriate focus behavior.
The default focus handler for a widget should return True
if
moving in direction
left the focus on a focusable location inside
that widget, and False
if moving in direction
moved the focus
outside the widget. If returning True
, widgets normally
call widgetGrabFocus
to place the focus accordingly;
if returning False
, they don’t modify the current focus location.
childNotify
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Text |
|
-> m () |
Emits a childNotify signal for the
[child property][child-properties] childProperty
on widget
.
This is the analogue of objectNotify
for child properties.
Also see containerChildNotify
.
classPath
Deprecated: (Since version 3.0)Use widgetGetPath
instead
Same as widgetPath
, but always uses the name of a widget’s type,
never uses a custom name set with widgetSetName
.
computeExpand
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Orientation |
|
-> m Bool | Returns: whether widget tree rooted here should be expanded |
Computes whether a container should give this widget extra space
when possible. Containers should check this, rather than
looking at widgetGetHexpand
or widgetGetVexpand
.
This function already checks whether the widget is visible, so visibility does not need to be checked separately. Non-visible widgets are not expanded.
The computed expand value uses either the expand setting explicitly set on the widget itself, or, if none has been explicitly set, the widget may expand if some of its children do.
createPangoContext
widgetCreatePangoContext Source #
Creates a new Context
with the appropriate font map,
font options, font description, and base direction for drawing
text for this widget. See also widgetGetPangoContext
.
createPangoLayout
widgetCreatePangoLayout Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Maybe Text |
|
-> m Layout | Returns: the new |
Creates a new Layout
with the appropriate font map,
font description, and base direction for drawing text for
this widget.
If you keep a Layout
created in this way around, you need
to re-create it when the widget Context
is replaced.
This can be tracked by using the screenChanged signal
on the widget.
destroy
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Destroys a widget.
When a widget is destroyed all references it holds on other objects will be released:
- if the widget is inside a container, it will be removed from its parent
- if the widget is a container, all its children will be destroyed, recursively
- if the widget is a top level, it will be removed from the list of top level widgets that GTK+ maintains internally
It's expected that all references held on the widget will also
be released; you should connect to the destroy signal
if you hold a reference to widget
and you wish to remove it when
this function is called. It is not necessary to do so if you are
implementing a Container
, as you'll be able to use the
ContainerClass
.remove
() virtual function for that.
It's important to notice that widgetDestroy
will only cause
the widget
to be finalized if no additional references, acquired
using objectRef
, are held on it. In case additional references
are in place, the widget
will be in an "inert" state after calling
this function; widget
will still point to valid memory, allowing you
to release the references you hold, but you may not query the widget's
own state.
You should typically call this function on top level widgets, and rarely on child widgets.

destroyed
:: (HasCallStack, MonadIO m, IsWidget a, IsWidget b) | |
=> a |
|
-> b |
|
-> m Widget |
This function sets *widgetPointer
to Nothing
if widgetPointer
!=
Nothing
. It’s intended to be used as a callback connected to the
“destroy” signal of a widget. You connect widgetDestroyed
as a signal handler, and pass the address of your widget variable
as user data. Then when the widget is destroyed, the variable will
be set to Nothing
. Useful for example to avoid multiple copies
of the same dialog.
deviceIsShadowed
widgetDeviceIsShadowed Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsDevice b) | |
=> a |
|
-> b |
|
-> m Bool | Returns: |
Returns True
if device
has been shadowed by a GTK+
device grab on another widget, so it would stop sending
events to widget
. This may be used in the
grabNotify signal to check for specific
devices. See deviceGrabAdd
.

dragBegin
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> TargetList |
|
-> [DragAction] |
|
-> Int32 |
|
-> Maybe Event |
|
-> m DragContext | Returns: the context for this drag |
Deprecated: (Since version 3.10)Use widgetDragBeginWithCoordinates
instead
This function is equivalent to widgetDragBeginWithCoordinates
,
passing -1, -1 as coordinates.
dragBeginWithCoordinates
widgetDragBeginWithCoordinates Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

-> TargetList |
|
-> [DragAction] |
|
-> Int32 |
|
-> Maybe Event |
|
-> Int32 |
|
-> Int32 |
|
-> m DragContext | Returns: the context for this drag |
Initiates a drag on the source side. The function only needs to be used
when the application is starting drags itself, and is not needed when
widgetDragSourceSet
is used.
The event
is used to retrieve the timestamp that will be used internally to
grab the pointer. If event
is Nothing
, then CURRENT_TIME
will be used.
However, you should try to pass a real event in all cases, since that can be
used to get information about the drag.
Generally there are three cases when you want to start a drag by hand by calling this function:
- During a buttonPressEvent handler, if you want to start a drag
immediately when the user presses the mouse button. Pass the
event
that you have in your buttonPressEvent handler. - During a motionNotifyEvent handler, if you want to start a drag
when the mouse moves past a certain threshold distance after a button-press.
Pass the
event
that you have in your motionNotifyEvent handler. - During a timeout handler, if you want to start a drag after the mouse
button is held down for some time. Try to save the last event that you got
from the mouse, using
eventCopy
, and pass it to this function (remember to free the event witheventFree
when you are done). If you really cannot pass a real event, passNothing
instead.

Checks to see if a mouse drag starting at (startX
, startY
) and ending
at (currentX
, currentY
) has passed the GTK+ drag threshold, and thus
should trigger the beginning of a drag-and-drop operation.
dragDestAddImageTargets
widgetDragDestAddImageTargets Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

|
-> m (Maybe Atom) | Returns: first target that the source offers
and the dest can accept, or |
Looks for a match between the supported targets of context
and the
destTargetList
, returning the first matching target, otherwise
returning GDK_NONE
. destTargetList
should usually be the return
value from widgetDragDestGetTargetList
, but some widgets may
have different valid targets for different parts of the widget; in
that case, they will have to implement a drag_motion handler that
passes the correct target list to this function.
dragDestGetTargetList
widgetDragDestGetTargetList Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m (Maybe TargetList) | Returns: the |
Returns the list of targets this widget can accept from drag-and-drop.
dragDestGetTrackMotion
widgetDragDestGetTrackMotion Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

Returns whether the widget has been configured to always emit dragMotion signals.
Since: 2.10
dragDestSet
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> [DestDefaults] |
|
-> Maybe [TargetEntry] |
|
-> [DragAction] |
|
-> m () |
Sets a widget as a potential drop destination, and adds default behaviors.
The default behaviors listed in flags
have an effect similar
to installing default handlers for the widget’s drag-and-drop signals
([dragMotion](GI.Gtk.Objects.Widget), dragDrop, ...). They all exist
for convenience. When passing GTK_DEST_DEFAULT_ALL
for instance it is
sufficient to connect to the widget’s dragDataReceived
signal to get primitive, but consistent drag-and-drop support.
Things become more complicated when you try to preview the dragged data,
as described in the documentation for dragMotion. The default
behaviors described by flags
make some assumptions, that can conflict
with your own signal handlers. For instance GTK_DEST_DEFAULT_DROP
causes
invokations of dragStatus
in the context of dragMotion,
and invokations of dragFinish
in dragDataReceived.
Especially the later is dramatic, when your own dragMotion
handler calls widgetDragGetData
to inspect the dragged data.
There’s no way to set a default action here, you can use the dragMotion callback for that. Here’s an example which selects the action to use depending on whether the control key is pressed or not:
C code
static void drag_motion (GtkWidget *widget, GdkDragContext *context, gint x, gint y, guint time) { GdkModifierType mask; gdk_window_get_pointer (gtk_widget_get_window (widget), NULL, NULL, &mask); if (mask & GDK_CONTROL_MASK) gdk_drag_status (context, GDK_ACTION_COPY, time); else gdk_drag_status (context, GDK_ACTION_MOVE, time); }
dragDestSetProxy

:: (HasCallStack, MonadIO m, IsWidget a, IsWindow b) | |
=> a |
|
-> b |

Deprecated: (Since version 3.22)
Sets this widget as a proxy for drops to another window.
dragDestSetTargetList
widgetDragDestSetTargetList Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Maybe TargetList |
|
-> m () |
Sets the target types that this widget can accept from drag-and-drop.
The widget must first be made into a drag destination with
widgetDragDestSet
.
dragDestSetTrackMotion
widgetDragDestSetTrackMotion Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Tells the widget to emit dragMotion and
dragLeave events regardless of the targets and the
DestDefaultsMotion
flag.
This may be used when a widget wants to do generic actions regardless of the targets that the source offers.
Since: 2.10
dragDestUnset
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Clears information about a drop destination set with
widgetDragDestSet
. The widget will no longer receive
notification of drags.
dragGetData
:: (HasCallStack, MonadIO m, IsWidget a, IsDragContext b) | |
=> a |
|
-> b |
|
-> Atom |
|
-> Word32 |
|
-> m () |
Gets the data associated with a drag. When the data
is received or the retrieval fails, GTK+ will emit a
dragDataReceived signal. Failure of the retrieval
is indicated by the length field of the selectionData
signal parameter being negative. However, when widgetDragGetData
is called implicitely because the DestDefaultsDrop
was set,
then the widget will not receive notification of failed
drops.
dragHighlight
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Highlights a widget as a currently hovered drop target.
To end the highlight, call widgetDragUnhighlight
.
GTK+ calls this automatically if DestDefaultsHighlight
is set.
dragSourceAddImageTargets
widgetDragSourceAddImageTargets Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |

Sets the icon that will be used for drags from a particular widget
from a Pixbuf
. GTK+ retains a reference for pixbuf
and will
release it when it is no longer needed.
dragSourceSetIconStock

Removes a highlight set by widgetDragHighlight
from
a widget.
draw
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Context |
|
-> m () |
Draws widget
to cr
. The top left corner of the widget will be
drawn to the currently set origin point of cr
.
You should pass a cairo context as cr
argument that is in an
original state. Otherwise the resulting drawing is undefined. For
example changing the operator using cairo_set_operator()
or the
line width using cairo_set_line_width()
might have unwanted side
effects.
You may however change the context’s transform matrix - like with
cairo_scale()
, cairo_translate()
or cairo_set_matrix()
and clip
region with cairo_clip()
prior to calling this function. Also, it
is fine to modify the context with cairo_save()
and
cairo_push_group()
prior to calling this function.
Note that special-purpose widgets may contain special code for
rendering to the screen and might appear differently on screen
and when rendered using widgetDraw
.
Since: 3.0
ensureStyle
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Deprecated: (Since version 3.0)Use StyleContext
instead
Ensures that widget
has a style (widget
->style).
Not a very useful function; most of the time, if you want the style, the widget is realized, and realized widgets are guaranteed to have a style already.
errorBell
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Notifies the user about an input-related error on this widget.
If the Settings
:gtk-error-bell
setting is True
, it calls
windowBeep
, otherwise it does nothing.
Note that the effect of windowBeep
can be configured in many
ways, depending on the windowing backend and the desktop environment
or window manager that is used.
Since: 2.12
event
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Event |
|
-> m Bool | Returns: return from the event signal emission ( |
Rarely-used function. This function is used to emit
the event signals on a widget (those signals should never
be emitted without using this function to do so).
If you want to synthesize an event though, don’t use this function;
instead, use mainDoEvent
so the event will behave as if
it were in the event queue. Don’t synthesize expose events; instead,
use windowInvalidateRect
to invalidate a region of the
window.
freezeChildNotify
widgetFreezeChildNotify Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Stops emission of childNotify signals on widget
. The
signals are queued until widgetThawChildNotify
is called
on widget
.
This is the analogue of objectFreezeNotify
for child properties.
getAccessible
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Object | Returns: the |
Returns the accessible object that describes the widget to an assistive technology.
If accessibility support is not available, this Object
instance may be a no-op. Likewise, if no class-specific Object
implementation is available for the widget instance in question,
it will inherit an Object
implementation from the first ancestor
class for which such an implementation is defined.
The documentation of the ATK library contains more information about accessible objects and their uses.
getActionGroup
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Text |
|
-> m (Maybe ActionGroup) | Returns: A |
Retrieves the ActionGroup
that was registered using prefix
. The resulting
ActionGroup
may have been registered to widget
or any Widget
in its
ancestry.
If no action group was found matching prefix
, then Nothing
is returned.

This function is intended to be used when implementing handlers
for the draw function.
getAllocatedSize
widgetGetAllocatedSize Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m (Rectangle, Int32) |
Retrieves the widget’s allocated size.
This function returns the last values passed to
widgetSizeAllocateWithBaseline
. The value differs from
the size returned in widgetGetAllocation
in that functions
like widgetSetHalign
can adjust the allocation, but not
the value returned by this function.
If a widget is not visible, its allocated size is 0.
Since: 3.20
getAllocatedWidth
widgetGetAllocatedWidth Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Int32 | Returns: the width of the |
Returns the width that has currently been allocated to widget
.
This function is intended to be used when implementing handlers
for the draw function.
getAllocation
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Rectangle |
Retrieves the widget’s allocation.
Note, when implementing a Container
: a widget’s allocation will
be its “adjusted” allocation, that is, the widget’s parent
container typically calls widgetSizeAllocate
with an
allocation, and that allocation is then adjusted (to handle margin
and alignment for example) before assignment to the widget.
widgetGetAllocation
returns the adjusted allocation that
was actually assigned to the widget. The adjusted allocation is
guaranteed to be completely contained within the
widgetSizeAllocate
allocation, however. So a Container
is guaranteed that its children stay inside the assigned bounds,
but not that they have exactly the bounds the container assigned.
There is no way to get the original allocation assigned by
widgetSizeAllocate
, since it isn’t stored; if a container
implementation needs that information it will have to track it itself.
Since: 2.18
getAncestor
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> GType |
|
-> m (Maybe Widget) | Returns: the ancestor widget, or |
Gets the first ancestor of widget
with type widgetType
. For example,
gtk_widget_get_ancestor (widget, GTK_TYPE_BOX)
gets
the first Box
that’s an ancestor of widget
. No reference will be
added to the returned widget; it should not be unreferenced. See note
about checking for a toplevel Window
in the docs for
widgetGetToplevel
.
Note that unlike widgetIsAncestor
, widgetGetAncestor
considers widget
to be an ancestor of itself.
getAppPaintable

getChildRequisition
widgetGetChildRequisition Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Requisition |
Deprecated: (Since version 3.0)Use widgetGetPreferredSize
instead.
This function is only for use in widget implementations. Obtains
widget
->requisition, unless someone has forced a particular
geometry on the widget (e.g. with widgetSetSizeRequest
),
in which case it returns that geometry instead of the widget's
requisition.
This function differs from widgetSizeRequest
in that
it retrieves the last size request value from widget
->requisition,
while widgetSizeRequest
actually calls the "size_request" method
on widget
to compute the size request and fill in widget
->requisition,
and only then returns widget
->requisition.
Because this function does not call the “size_request” method, it
can only be used when you know that widget
->requisition is
up-to-date, that is, widgetSizeRequest
has been called
since the last time a resize was queued. In general, only container
implementations have this information; applications should use
widgetSizeRequest
.
getChildVisible
widgetGetChildVisible Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Gets the value set with widgetSetChildVisible
.
If you feel a need to use this function, your code probably
needs reorganization.
This function is only useful for container implementations and never should be called by an application.
getClip
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Rectangle |
Retrieves the widget’s clip area.
The clip area is the area in which all of widget
's drawing will
happen. Other toolkits call it the bounding box.
Historically, in GTK+ the clip area has been equal to the allocation
retrieved via widgetGetAllocation
.
Since: 3.14
getClipboard
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Atom |
|
-> m Clipboard | Returns: the appropriate clipboard object. If no clipboard already exists, a new one will be created. Once a clipboard object has been created, it is persistent for all time. |
Returns the clipboard object for the given selection to
be used with widget
. widget
must have a Display
associated with it, so must be attached to a toplevel
window.

Returns the default style used by all widgets initially.
getDeviceEnabled
widgetGetDeviceEnabled Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsDevice b) | |

Returns the events mask for the widget corresponding to an specific device. These
are the events that the widget will receive when device
operates on it.
Since: 3.0
getDirection
:: (HasCallStack, MonadIO m, IsWidget a) | |

.
getDisplay
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Display | Returns: the |
Get the Display
for the toplevel window associated with
this widget. This function can only be called after the widget
has been added to a widget hierarchy with a Window
at the top.
In general, you should only create display specific resources when a widget has been realized, and you should free those resources when the widget is unrealized.
Since: 2.2
getDoubleBuffered
getEvents
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Int32 | Returns: event mask for |
Returns the event mask (see EventMask
) for the widget. These are the
events that the widget will receive.
Note: Internally, the widget event mask will be the logical OR of the event
mask set through widgetSetEvents
or widgetAddEvents
, and the
event mask necessary to cater for every EventController
created for the
widget.
getFocusOnClick
widgetGetFocusOnClick Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |

the defaults font options for the Screen
will be used.
Since: 3.18
getFrameClock
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m (Maybe FrameClock) | Returns: a |
Obtains the frame clock for a widget. The frame clock is a global
“ticker” that can be used to drive animations and repaints. The
most common reason to get the frame clock is to call
frameClockGetFrameTime
, in order to get a time to use for
animating. For example you might record the start of the animation
with an initial value from frameClockGetFrameTime
, and
then update the animation by calling
frameClockGetFrameTime
again during each repaint.
frameClockRequestPhase
will result in a new frame on the
clock, but won’t necessarily repaint any widgets. To repaint a
widget, you have to use widgetQueueDraw
which invalidates
the widget (thus scheduling it to receive a draw on the next
frame). widgetQueueDraw
will also end up requesting a frame
on the appropriate frame clock.
A widget’s frame clock will not change while the widget is mapped. Reparenting a widget (which implies a temporary unmap) can change the widget’s frame clock.
Unrealized widgets do not have a frame clock.

getHalign
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Align | Returns: the horizontal alignment of |
Gets the value of the Widget
:halign
property.
For backwards compatibility reasons this method will never return
AlignBaseline
, but instead it will convert it to
AlignFill
. Baselines are not supported for horizontal
alignment.
getHasTooltip
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: current value of has-tooltip on |
Returns the current value of the has-tooltip property. See
Widget
:has-tooltip
for more information.

getHasWindow
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool |
Determines whether widget
has a Window
of its own. See
widgetSetHasWindow
.
Since: 2.18
getHexpand
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: whether hexpand flag is set |
Gets whether the widget would like any available extra horizontal
space. When a user resizes a Window
, widgets with expand=TRUE
generally receive the extra space. For example, a list or
scrollable area or document in your window would often be set to
expand.
Containers should use widgetComputeExpand
rather than
this function, to see whether a widget, or any of its children,
has the expand flag set. If any child of a widget wants to
expand, the parent may ask to expand also.
This function only looks at the widget’s own hexpand flag, rather than computing whether the entire widget tree rooted at this widget wants to expand.
getHexpandSet
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: whether hexpand has been explicitly set |
Gets whether widgetSetHexpand
has been used to
explicitly set the expand flag on this widget.
If hexpand is set, then it overrides any computed expand value based on child widgets. If hexpand is not set, then the expand value depends on whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here for completeness and consistency.
getMapped
:: (HasCallStack, MonadIO m, IsWidget a) | |

This rc style is owned by the widget. If you want to keep a
pointer to value this around, you must add a refcount using
|
Deprecated: (Since version 3.0)Use StyleContext
with a custom StyleProvider
instead
Returns the current modifier style for the widget. (As set by
widgetModifyStyle
.) If no style has previously set, a new
RcStyle
will be created with all values unset, and set as the
modifier style for the widget. If you make changes to this rc
style, you must call widgetModifyStyle
, passing in the
returned rc style, to make sure that your changes take effect.
Caution: passing the style back to widgetModifyStyle
will
normally end up destroying it, because widgetModifyStyle
copies
the passed-in style and sets the copy as the new modifier style,
thus dropping any reference to the old modifier style. Add a reference
to the modifier style if you want to keep it alive.
getName
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Text | Returns: name of the widget. This string is owned by GTK+ and should not be modified or freed |
Retrieves the name of a widget. See widgetSetName

:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Context | Returns: the |
Gets a Context
with the appropriate font map, font description,
and base direction for this widget. Unlike the context returned
by widgetCreatePangoContext
, this context is owned by
the widget (it can be used until the screen for the widget changes
or the widget is removed from its toplevel), and will be updated to
match any changes to the widget’s attributes. This can be tracked
by using the screenChanged signal on the widget.
getParent
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

Returns the WidgetPath
representing widget
, if the widget
is not connected to a toplevel widget, a partial path will be
created.
getPointer
Deprecated: (Since version 3.4)Use windowGetDevicePosition
instead.
Obtains the location of the mouse pointer in widget coordinates.
Widget coordinates are a bit odd; for historical reasons, they are
defined as widget
->window coordinates for widgets that return True
for
widgetGetHasWindow
; and are relative to widget
->allocation.x,
widget
->allocation.y otherwise.
getPreferredHeight
widgetGetPreferredHeight Source #
Retrieves a widget’s initial minimum and natural height.
This call is specific to width-for-height requests.
The returned request will be modified by the
GtkWidgetClass[adjust_size_request](#signal:adjust_size_request) virtual method and by any
GtkSizeGroups
that have been applied. That is, the returned request
is the one that should be used for layout, not necessarily the one
returned by the widget itself.

-> m (Int32, Int32, Int32, Int32) |
Retrieves a widget’s minimum and natural height and the corresponding baselines if it would be given
the specified width
, or the default height if width
is -1. The baselines may be -1 which means
that no baseline is requested for this widget.
The returned request will be modified by the
GtkWidgetClass[adjust_size_request](signal:adjust_baseline_request) virtual methods

Since: 3.0
getPreferredSize
widgetGetPreferredSize Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m (Requisition, Requisition) |
Retrieves the minimum and natural size of a widget, taking into account the widget’s preference for height-for-width management.
This is used to retrieve a suitable size by container widgets which do not impose any restrictions on the child placement. It can be used to deduce toplevel window and menu sizes as well as child widgets in free-form containers such as GtkLayout.
Handle with care. Note that the natural height of a height-for-width widget will generally be a smaller size than the minimum height, since the required height for the natural width is generally smaller than the required height for the minimum width.
Use widgetGetPreferredHeightAndBaselineForWidth
if you want to support
baseline alignment.
Since: 3.0
getPreferredWidth
widgetGetPreferredWidth Source #
Retrieves a widget’s initial minimum and natural width.
This call is specific to height-for-width requests.
The returned request will be modified by the

Determines whether widget
is always treated as the default widget
within its toplevel when it has the focus, even if another widget
is the default.
Since: 2.18
getRequestMode
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m SizeRequestMode | Returns: The |
Gets whether the widget prefers a height-for-width layout or a width-for-height layout.
Bin
widgets generally propagate the preference of
their child, container widgets need to request something either in
context of their children or in context of their allocation
capabilities.
Since: 3.0
getRequisition

=> a |
|
-> m Requisition |
Deprecated: (Since version 3.0)The Requisition
cache on the widget wasremoved, If you need to cache sizes across requests and allocations,add an explicit cache to the widget in question instead.
Retrieves the widget’s requisition.
This function should only be used by widget implementations in
order to figure whether the widget’s requisition has actually
changed after some internal state change (so that they can call
widgetQueueResize
instead of widgetQueueDraw
).
Normally, widgetSizeRequest
should be used.
Since: 2.20
getRootWindow
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Window | Returns: the |
Deprecated: (Since version 3.12)Use screenGetRootWindow
instead
Get the root window where this widget is located. This function can
only be called after the widget has been added to a widget
hierarchy with Window
at the top.
The root window is useful for such purposes as creating a popup
Window
associated with the window. In general, you should only
create display specific resources when a widget has been realized,
and you should free those resources when the widget is unrealized.
Since: 2.2
getScaleFactor
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Int32 | Returns: the scale factor for |
Retrieves the internal scale factor that maps from window coordinates to the actual device pixels. On traditional systems this is 1, on high density outputs, it can be a higher value (typically 2).
See windowGetScaleFactor
.
Since: 3.10
getScreen
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Screen | Returns: the |
Get the Screen
from the toplevel window associated with
this widget. This function can only be called after the widget
has been added to a widget hierarchy with a Window
at the top.
In general, you should only create screen specific resources when a widget has been realized, and you should free those resources when the widget is unrealized.
Since: 2.2
getSensitive
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Returns the widget’s sensitivity (in the sense of returning
the value that has been set using widgetSetSensitive
).
The effective sensitivity of a widget is however determined by both its
own and its parent widget’s sensitivity. See widgetIsSensitive
.
Since: 2.18
getSettings
getSizeRequest
Gets the size request that was explicitly set for the widget using
widgetSetSizeRequest
. A value of -1 stored in width
or
height
indicates that that dimension has not been set explicitly
and the natural requisition of the widget will be used instead. See
widgetSetSizeRequest
. To get the size a widget will
actually request, call widgetGetPreferredSize
instead of
this function.
getState
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m StateType | Returns: the state of |
Deprecated: (Since version 3.0)Use widgetGetStateFlags

Returns the widget’s state. See widgetSetState
.
Since: 2.18
getStateFlags
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m [StateFlags] | Returns: The state flags for widget |
Returns the widget state as a flag set. It is worth mentioning
that the effective StateFlagsInsensitive
state will be
returned, that is, also based on parent insensitivity, even if
widget
itself is sensitive.
Also note that if you are looking for a way to obtain the
StateFlags
to pass to a StyleContext
method, you
should look at styleContextGetState
.
Since: 3.0
getStyle
Deprecated: (Since version 3.0)Use StyleContext
instead
Simply an accessor function that returns widget
->style.
getStyleContext
widgetGetStyleContext Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |

guaranteed to be the same for the lifetime of widget
.
getSupportMultidevice
widgetGetSupportMultidevice Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |

|
-> GType |
|
-> Text |
|
-> m Object | Returns: The object built in the template XML with the id |
Fetch an object build from the template XML for widgetType
in this widget
instance.
This will only report children which were previously declared with
widgetClassBindTemplateChildFull
or one of its
variants.
This function is only meant to be called for code which is private to the widgetType
which
declared the child and is meant for language bindings which cannot easily make use
of the GObject structure offsets.
getTooltipMarkup
widgetGetTooltipMarkup Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |

GtkWindow created by default, or the custom tooltip window set
using widgetSetTooltipWindow
.
Since: 2.12
getToplevel
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Widget | Returns: the topmost ancestor of |
This function returns the topmost widget in the container hierarchy
widget
is a part of. If widget
has no parent widgets, it will be
returned as the topmost widget. No reference will be added to the
returned widget; it should not be unreferenced.
Note the difference in behavior vs. widgetGetAncestor
;
gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW)
would return
Nothing
if widget
wasn’t inside a toplevel window, and if the
window was inside a Window
-derived widget which was in turn
inside the toplevel Window
. While the second case may
seem unlikely, it actually happens when a Plug
is embedded
inside a Socket
within the same application.
To reliably find the toplevel Window
, use
widgetGetToplevel
and call GTK_IS_WINDOW()
on the result. For instance, to get the title of a widget's toplevel
window, one might use:
C code
static const char * get_widget_toplevel_title (GtkWidget *widget) { GtkWidget *toplevel = gtk_widget_get_toplevel (widget); if (GTK_IS_WINDOW (toplevel)) { return gtk_window_get_title (GTK_WINDOW (toplevel)); } return NULL; }
getValign
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Align | Returns: the vertical alignment of |
Gets the value of the Widget
:valign
property.
For backwards compatibility reasons this method will never return
AlignBaseline
, but instead it will convert it to
AlignFill
. If your widget want to support baseline aligned
children it must use widgetGetValignWithBaseline
, or
g_object_get (widget, "valign", &value, NULL)
, which will
also report the true value.
getValignWithBaseline
widgetGetValignWithBaseline Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |

-> m Align | Returns: the vertical alignment of |
Gets the value of the Widget
:valign
property, including
AlignBaseline
.

See widgetGetHexpand
for more detail.
getVexpandSet
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: whether vexpand has been explicitly set |
Gets whether widgetSetVexpand
has been used to
explicitly set the expand flag on this widget.
See widgetGetHexpandSet
for more detail.
getVisible
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Determines whether the widget is visible. If you want to
take into account whether the widget’s parent is also marked as
visible, use widgetIsVisible
instead.
This function does not check if the widget is obscured in any way.
See widgetSetVisible
.

Returns the widget’s window if it is realized, Nothing
otherwise
Since: 2.14
grabAdd
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Makes widget
the current grabbed widget.
This means that interaction with other widgets in the same application is blocked and mouse as well as keyboard events are delivered to this widget.
If widget
is not sensitive, it is not set as the current
grabbed widget and this function does nothing.
grabDefault
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Causes widget
to become the default widget. widget
must be able to be
a default widget; typically you would ensure this yourself
by calling widgetSetCanDefault
with a True
value.
The default widget is activated when
the user presses Enter in a window. Default widgets must be
activatable, that is, widgetActivate
should affect them. Note
that Entry
widgets require the “activates-default” property
set to True
before they activate the default widget when Enter
is pressed and the Entry
is focused.
grabFocus
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Causes widget
to have the keyboard focus for the Window
it's
inside. widget
must be a focusable widget, such as a Entry
;
something like Frame
won’t work.
More precisely, it must have the GTK_CAN_FOCUS
flag set. Use
widgetSetCanFocus
to modify that flag.
The widget also needs to be realized and mapped. This is indicated by the related signals. Grabbing the focus immediately after creating the widget will likely fail and cause critical warnings.
grabRemove
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Removes the grab from the given widget.
You have to pair calls to widgetGrabAdd
and widgetGrabRemove
.
If widget
does not have the grab, this function does nothing.
hasDefault
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Determines whether widget
is the current default widget within its
toplevel. See widgetSetCanDefault
.
Since: 2.18
hasFocus
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Determines if the widget has the global input focus. See
widgetIsFocus
for the difference between having the global
input focus, and only having the focus within a toplevel.
Since: 2.18
hasGrab
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Determines whether the widget is currently grabbing events, so it is the only widget receiving input events (keyboard and mouse).
See also widgetGrabAdd
.
Since: 2.18
hasRcStyle
:: (HasCallStack, MonadIO m, IsWidget a) | |

Determines if the widget style has been looked up through the rc mechanism.
Since: 2.20
hasScreen
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Checks whether there is a Screen
is associated with
this widget. All toplevel widgets have an associated
screen, and all widgets added into a hierarchy with a toplevel
window at the top.
Since: 2.2
hasVisibleFocus
widgetHasVisibleFocus Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Determines if the widget should show a visible indication that
it has the global input focus. This is a convenience function for
use in draw handlers that takes into account whether focus
indication should currently be shown in the toplevel window of
widget
. See windowGetFocusVisible
for more information
about focus indication.
To find out if the widget has the global input focus, use
widgetHasFocus
.
Since: 3.2
hide
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Reverses the effects of widgetShow
, causing the widget to be
hidden (invisible to the user).
hideOnDelete
Utility function; intended to be connected to the deleteEvent
signal on a Window
. The function calls widgetHide
on its
argument, then returns True
. If connected to deleteEvent, the
result is that clicking the close button for a window (on the
window frame, top right corner usually) will hide but not destroy
the window. By default, GTK+ destroys windows when deleteEvent
is received.
inDestruction
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Returns whether the widget is currently being destroyed. This information can sometimes be used to avoid doing unnecessary work.
initTemplate
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Creates and initializes child widgets defined in templates. This
function must be called in the instance initializer for any
class which assigned itself a template using widgetClassSetTemplate
It is important to call this function in the instance initializer
of a Widget
subclass and not in Object
.constructed
() or
Object
.constructor
() for two reasons.
One reason is that generally derived widgets will assume that parent class composite widgets have been created in their instance initializers.
Another reason is that when calling g_object_new()
on a widget with
composite templates, it’s important to build the composite widgets
before the construct properties are set. Properties passed to g_object_new()
should take precedence over properties set in the private template XML.

inputShapeCombineRegion
widgetInputShapeCombineRegion Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

widgetInsertActionGroup Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsActionGroup b) | |
=> a |

. Children of widget
that implement
Actionable
can then be associated with actions in group
by
setting their “action-name” to
prefix
.action-name
.
If group
is Nothing

is somewhere inside ancestor
, possibly with
intermediate containers.
isComposited
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m Bool | Returns: |
Deprecated: (Since version 3.22)Use screenIsComposited
instead.
Whether widget
can rely on having its alpha channel
drawn correctly. On X11 this function returns whether a
compositing manager is running for widget
’s screen.
Please note that the semantics of this call will change
in the future if used on a widget that has a composited
window in its hierarchy (as set by windowSetComposited
).
Since: 2.10
isDrawable
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|

to if it is mapped and visible.
Since: 2.18
isFocus
isSensitive
:: (HasCallStack, MonadIO m, IsWidget a) | |

Since: 3.8
keynavFailed
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> DirectionType |
|
-> m Bool | Returns: |
This function should be called whenever keyboard navigation within
a single widget hits a boundary. The function emits the
keynavFailed signal on the widget and its return
value should be interpreted in a way similar to the return value of
widgetChildFocus
:
When True
is returned, stay in the widget, the failed keyboard
navigation is OK and/or there is nowhere we can/should move the
focus to.
When False
is returned, the caller should continue with keyboard
navigation outside the widget, e.g. by calling
widgetChildFocus
on the widget’s toplevel.
The default keynavFailed handler returns False
for
DirectionTypeTabForward
and DirectionTypeTabBackward
. For the other
values of DirectionType
it returns True
.
Whenever the default handler returns True
, it also calls
widgetErrorBell
to notify the user of the failed keyboard
navigation.
A use case for providing an own implementation of keynavFailed
(either by connecting to it or by overriding it) would be a row of
Entry
widgets where the user should be able to navigate the
entire row with the cursor keys, as e.g. known from user interfaces
that require entering license keys.

Returns a newly allocated list of the widgets, normally labels, for
which this widget is the target of a mnemonic (see for example,
labelSetMnemonicWidget
).
The widgets in the list are not individually referenced. If you
want to iterate through the list and perform actions involving
callbacks that might destroy the widgets, you
must call g_list_foreach (result,
(GFunc)g_object_ref, NULL)
first, and then unref all the
widgets afterwards.

Deprecated: (Since version 3.0)Use widgetOverrideBackgroundColor
instead
Sets the base color for a widget in a particular state.
All other style values are left untouched. The base color
is the background color used along with the text color
(see widgetModifyText
) for widgets such as Entry
and TextView
. See also widgetModifyStyle
.
Note that “no window” widgets (which have the @/GTK_NO_WINDOW/@ flag set) draw on their parent container’s window and thus may not draw any background themselves. This is the case for e.g. t'GI.Gtk.Objects.Label.Label'. To modify the background of such widgets, you have to set the base color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a t'GI.Gtk.Objects.EventBox.EventBox' widget and setting the base color on that.

Modifies style values on the widget.
Modifications made using this technique take precedence over
style values set via an RC file, however, they will be overridden
if a style is explicitly set on the widget using widgetSetStyle
.
The RcStyle
-struct is designed so each field can either be
set or unset, so it is possible, using this function, to modify some
style values and leave the others unchanged.
Note that modifications made with this function are not cumulative
with previous calls to widgetModifyStyle
or with such
functions as widgetModifyFg
. If you wish to retain
previous values, you must first call widgetGetModifierStyle
,
make your modifications to the returned style, then call
widgetModifyStyle
with that style. On the other hand,
if you first call widgetModifyStyle
, subsequent calls
to such functions widgetModifyFg
will have a cumulative
effect with the initial modifications.

Deprecated: (Since version 3.16)Use a custom style provider and style classes instead
Sets the color to use for a widget.
All other style values are left untouched.
This function does not act recursively. Setting the color of a
container does not affect its children. Note that some widgets that
you may not think of as containers, for instance GtkButtons
,
are actually containers.
This API is mostly meant as a quick way for applications to
change a widget appearance. If you are developing a widgets
library and intend this change to be themeable, it is better
done by setting meaningful CSS classes in your
widget/container implementation through styleContextAddClass
.
This way, your widget library can install a CssProvider
with the STYLE_PROVIDER_PRIORITY_FALLBACK
priority in order
to provide a default styling for those widgets that need so, and
this theming may fully overridden by the user’s theme.
Note that for complex widgets this may bring in undesired
results (such as uniform background color everywhere), in
these cases it is better to fully style such widgets through a
CssProvider
with the STYLE_PROVIDER_PRIORITY_APPLICATION
priority.

path
Deprecated: (Since version 3.0)Use widgetGetPath
instead
Obtains the full path to widget
. The path is simply the name of a
widget and all its parents in the container hierarchy, separated by
periods. The name of a widget comes from
widgetGetName
. Paths are used to apply styles to a widget
in gtkrc configuration files. Widget names are the type of the
widget by default (e.g. “GtkButton”) or can be set to an
application-specific value with widgetSetName
. By setting
the name of a widget, you allow users or theme authors to apply
styles to that specific widget in their gtkrc
file. pathReversedP
fills in the path in reverse order,
i.e. starting with widget
’s name instead of starting with the name
of widget
’s outermost ancestor.
popCompositeChild
widgetPopCompositeChild :: (HasCallStack, MonadIO m) => m () Source #

widgetPushCompositeChild :: (HasCallStack, MonadIO m) => m () Source #
Deprecated: (Since version 3.10)This API never really worked well and was mostly unused, nowwe have a more complete mechanism for composite children, see widgetClassSetTemplate
.
Makes all newly-created widgets as composite children until
the corresponding widgetPopCompositeChild
call.
A composite child is a child that’s an implementation detail of the
container it’s inside and should not be visible to people using the
container. Composite children aren’t treated differently by GTK+ (but
see containerForeach
vs. containerForall
), but e.g. GUI
builders might want to treat them in a different way.
queueAllocate
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

-> m () |
This function is only for use in widget implementations.
Flags the widget for a rerun of the GtkWidgetClass[size_allocate](#signal:size_allocate)
function. Use this function instead of widgetQueueResize
when the widget
's size request didn't change but it wants to
reposition its contents.
An example user of this function is widgetSetHalign
.

=> a |
|
-> Int32 |

-> Int32 |
|
-> Int32 |
|
-> m () |
Convenience function that calls widgetQueueDrawRegion
on
the region created from the given coordinates.
The region here is specified in widget coordinates.
Widget coordinates are a bit odd; for historical reasons, they are
defined as widget
->window coordinates for widgets that return True
for
widgetGetHasWindow
, and are relative to widget
->allocation.x,
widget
->allocation.y otherwise.
width
or height
may be 0, in this case this function does
nothing. Negative values for width
and height
are not allowed.
queueDrawRegion
widgetQueueDrawRegion Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Region |
|
-> m () |
Invalidates the area of widget
defined by region
by calling
windowInvalidateRegion
on the widget’s window and all its
child windows. Once the main loop becomes idle (after the current
batch of events has been processed, roughly), the window will
receive expose events for the union of all regions that have been
invalidated.
Normally you would only use this function in widget
implementations. You might also use it to schedule a redraw of a
DrawingArea
or some portion thereof.
Since: 3.0
queueResize
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
This function is only for use in widget implementations.
Flags a widget to have its size renegotiated; should
be called when a widget for some reason has a new size request.
For example, when you change the text in a Label
, Label
queues a resize to ensure there’s enough space for the new text.
Note that you cannot call widgetQueueResize
on a widget
from inside its implementation of the GtkWidgetClass[size_allocate](#signal:size_allocate)
virtual method. Calls to widgetQueueResize
from inside
GtkWidgetClass[size_allocate](#signal:size_allocate) will be silently ignored.
queueResizeNoRedraw
widgetQueueResizeNoRedraw Source #

This function works like widgetQueueResize
,
except that the widget is not invalidated.
Since: 2.4
realize
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> m () |
Creates the GDK (windowing system) resources associated with a
widget. For example, widget
->window will be created when a widget
is realized. Normally realization happens implicitly; if you show
a widget and all its parent containers, then the widget will be
realized and mapped automatically.
Realizing a widget requires all
the widget’s parent widgets to be realized; calling
widgetRealize
realizes the widget’s parents in addition to
widget
itself. If a widget is not yet inside a toplevel window
when you realize it, bad things will happen.
This function is primarily used in widget implementations, and isn’t very useful otherwise. Many times when you think you might need it, a better approach is to connect to a signal that will be called after the widget is realized automatically, such as draw. Or simply g_signal_connect () to the realize signal.

check.
registerWindow
:: (HasCallStack, MonadIO m, IsWidget a, IsWindow b) | |
=> a |
|
-> b |
|
-> m () |
Registers a Window
with the widget and sets it up so that
the widget receives events for it. Call widgetUnregisterWindow
when destroying the window.
Before 3.8 you needed to call windowSetUserData
directly to set
this up. This is now deprecated and you should use widgetRegisterWindow
instead. Old code will keep working as is, although some new features like
transparency might not work perfectly.

resetStyle
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

Deprecated: (Since version 3.22)Application and widget code should not handle expose events directly; invalidation should use the Widget
API, and drawing should only happen inside draw implementations
Very rarely-used function. This function is used to emit
an expose event on a widget. This function is not normally used
directly. The only time it is used is when propagating an expose
event to a windowless child widget (widgetGetHasWindow
is False
),
and that is normally done using containerPropagateDraw
.
If you want to force an area of a window to be redrawn,
use windowInvalidateRect

:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |

-> m Bool | Returns: the return value from the event signal emission: |
Sends the focus change event

This function is not meant to be used by applications. The only time it
should be used is when it is necessary for a Widget
to assign focus
to a widget that is semantically owned by the first widget even though
it’s not a direct child - for instance, a search entry in a floating
window similar to the quick search in TreeView
.
An example of its usage is:
C code
GdkEvent *fevent = gdk_event_new (GDK_FOCUS_CHANGE); fevent->focus_change.type = GDK_FOCUS_CHANGE; fevent->focus_change.in = TRUE; fevent->focus_change.window = _gtk_widget_get_window (widget); if (fevent->focus_change.window != NULL) g_object_ref (fevent->focus_change.window); gtk_widget_send_focus_change (widget, fevent); gdk_event_free (event);

setAccelPath
:: (HasCallStack, MonadIO m, IsWidget a, IsAccelGroup b) | |
=> a |

-> Maybe Text |
|
-> Maybe b |
|
-> m () |
Given an accelerator group, accelGroup
, and an accelerator path,
accelPath
, sets up an accelerator in accelGroup
so whenever the
key binding that is defined for accelPath
is pressed, widget
will be activated. This removes any accelerators (for any
accelerator group) installed by previous calls to
widgetSetAccelPath
. Associating accelerators with
paths allows them to be modified by the user and the modifications
to be saved for future use. (See accelMapSave
.)
This function is a low level function that would most likely
be used by a menu creation system like UIManager
. If you
use UIManager
, setting up accelerator paths will be done
automatically.
Even when you you aren’t using UIManager
, if you only want to
set up accelerators on menu items menuItemSetAccelPath
provides a somewhat more convenient interface.
Note that accelPath
string will be stored in a GQuark
. Therefore, if you
pass a static string, you can save some memory by interning it first with
internStaticString
.
setAllocation
:: (HasCallStack, MonadIO m, IsWidget a) | |

Sets the widget’s allocation. This should not be used directly, but from within a widget’s size_allocate method.
The allocation set should be the “adjusted” or actual
allocation. If you’re implementing a Container
, you want to use
widgetSizeAllocate
instead of widgetSetAllocation
.
The GtkWidgetClass[adjust_size_allocation](#signal:adjust_size_allocation) virtual method adjusts the
allocation inside widgetSizeAllocate
to create an adjusted
allocation.

setAppPaintable
widgetSetAppPaintable Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets whether the application intends to draw on the widget in an draw handler.
This is a hint to the widget and does not affect the behavior of
the GTK+ core; many widgets ignore this flag entirely. For widgets
that do pay attention to the flag, such as EventBox
and Window
,
the effect is to suppress default themed drawing of the widget's
background. (Children of the widget will still be drawn.) The application
is then entirely responsible for drawing the widget background.
Note that the background is still drawn when the widget is mapped.
setCanDefault
:: (HasCallStack, MonadIO m, IsWidget a) | |

widget.
Since: 2.18
setChildVisible
widgetSetChildVisible Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets whether widget
should be mapped along with its when its parent
is mapped and widget
has been shown with widgetShow
.
The child visibility can be set for widget before it is added to
a container with widgetSetParent
, to avoid mapping
children unnecessary before immediately unmapping them. However
it will be reset to its default state of True
when the widget
is removed from a container.
Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself.
This function is only useful for container implementations and never should be called by an application.
setClip
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Rectangle |
|
-> m () |
Sets the widget’s clip. This must not be used directly,
but from within a widget’s size_allocate method.
It must be called after widgetSetAllocation
(or after chaining up
to the parent class), because that function resets the clip.
The clip set should be the area that widget
draws on. If widget
is a
Container
, the area must contain all children's clips.
If this function is not called by widget
during a sizeAllocate handler,
the clip will be set to widget
's allocation.
Since: 3.14
setCompositeName
widgetSetCompositeName Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Text |
|
-> m () |
Deprecated: (Since version 3.10)Use widgetClassSetTemplate
, or don’t use this API at all.
Sets a widgets composite name. The widget must be
a composite child of its parent; see widgetPushCompositeChild
.
setDefaultDirection
widgetSetDefaultDirection Source #
:: (HasCallStack, MonadIO m) | |
=> TextDirection |
|
-> m () |
Sets the default reading direction for widgets where the
direction has not been explicitly set by widgetSetDirection
.
setDeviceEnabled
widgetSetDeviceEnabled Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsDevice b) | |
=> a |
|
-> b |
|
-> Bool |
|
-> m () |
Enables or disables a Device
to interact with widget
and all its children.
It does so by descending through the Window
hierarchy
and enabling the same mask that is has for core events
(i.e. the one that windowGetEvents
returns).
Since: 3.0
setDeviceEvents
widgetSetDeviceEvents Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsDevice b) | |
=> a |
|
-> b |
|
-> [EventMask] |
|
-> m () |
Sets the device event mask (see EventMask
) for a widget. The event
mask determines which events a widget will receive from device
. Keep
in mind that different widgets have different default event masks, and by
changing the event mask you may disrupt a widget’s functionality,
so be careful. This function must be called while a widget is
unrealized. Consider widgetAddDeviceEvents
for widgets that are
already realized, or if you want to preserve the existing event
mask. This function can’t be used with windowless widgets (which return
False
from widgetGetHasWindow
);
to get events on those widgets, place them inside a EventBox
and receive events on the event box.
Since: 3.0
setDirection
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> TextDirection |
|
-> m () |
Sets the reading direction on a particular widget. This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitly visual rather than logical (such as buttons for text justification).
If the direction is set to TextDirectionNone
, then the value
set by widgetSetDefaultDirection
will be used.
setDoubleBuffered
widgetSetDoubleBuffered Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Deprecated: (Since version 3.14)This function does not work under non-X11 backends or withnon-native windows.It should not be used in newly written code.
Widgets are double buffered by default; you can use this function
to turn off the buffering. “Double buffered” simply means that
windowBeginDrawFrame
and windowEndDrawFrame
are called
automatically around expose events sent to the
widget. windowBeginDrawFrame
diverts all drawing to a widget's
window to an offscreen buffer, and windowEndDrawFrame
draws the
buffer to the screen. The result is that users see the window
update in one smooth step, and don’t see individual graphics
primitives being rendered.
In very simple terms, double buffered widgets don’t flicker, so you would only use this function to turn off double buffering if you had special needs and really knew what you were doing.
Note: if you turn off double-buffering, you have to handle
expose events, since even the clearing to the background color or
pixmap will not happen automatically (as it is done in
windowBeginDrawFrame
).
In 3.10 GTK and GDK have been restructured for translucent drawing. Since then expose events for double-buffered widgets are culled into a single event to the toplevel GDK window. If you now unset double buffering, you will cause a separate rendering pass for every widget. This will likely cause rendering problems - in particular related to stacking - and usually increases rendering times significantly.
setEvents
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> [EventMask] |
|
-> m () |
Sets the event mask (see EventMask
) for a widget. The event
mask determines which events a widget will receive. Keep in mind
that different widgets have different default event masks, and by
changing the event mask you may disrupt a widget’s functionality,
so be careful. This function must be called while a widget is
unrealized. Consider widgetAddEvents
for widgets that are
already realized, or if you want to preserve the existing event
mask. This function can’t be used with widgets that have no window.
(See widgetGetHasWindow
). To get events on those widgets,
place them inside a EventBox
and receive events on the event
box.
setFocusOnClick
widgetSetFocusOnClick Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets whether the widget should grab focus when it is clicked with the mouse. Making mouse clicks not grab focus is useful in places like toolbars where you don’t want the keyboard focus removed from the main area of the application.
Since: 3.20
setFontMap
:: (HasCallStack, MonadIO m, IsWidget a, IsFontMap b) | |
=> a |
|
-> Maybe b |
|
-> m () |
Sets the font map to use for Pango rendering. When not set, the widget will inherit the font map from its parent.
Since: 3.18
setFontOptions
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Maybe FontOptions |
|
-> m () |
Sets the FontOptions
used for Pango rendering in this widget.
When not set, the default font options for the Screen
will be used.
Since: 3.18
setHalign
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Align |
|
-> m () |
Sets the horizontal alignment of widget
.
See the Widget
:halign
property.
setHasTooltip
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets the has-tooltip property on widget
to hasTooltip
. See
Widget
:has-tooltip
for more information.
Since: 2.12
setHasWindow
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Specifies whether widget
has a Window
of its own. Note that
all realized widgets have a non-Nothing
“window” pointer
(widgetGetWindow
never returns a Nothing
window when a widget
is realized), but for many of them it’s actually the Window
of
one of its parent widgets. Widgets that do not create a window
for
themselves in realize must announce this by
calling this function with hasWindow
= False
.
This function should only be called by widget implementations,
and they should call it in their init()
function.
Since: 2.18
setHexpand
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets whether the widget would like any available extra horizontal
space. When a user resizes a Window
, widgets with expand=TRUE
generally receive the extra space. For example, a list or
scrollable area or document in your window would often be set to
expand.
Call this function to set the expand flag if you would like your widget to become larger horizontally when the window has extra room.
By default, widgets automatically expand if any of their children
want to expand. (To see if a widget will automatically expand given
its current children and state, call widgetComputeExpand
. A
container can decide how the expandability of children affects the
expansion of the container by overriding the compute_expand virtual
method on Widget
.).
Setting hexpand explicitly with this function will override the automatic expand behavior.
This function forces the widget to expand or not to expand,
regardless of children. The override occurs because
widgetSetHexpand
sets the hexpand-set property (see
widgetSetHexpandSet
) which causes the widget’s hexpand
value to be used, rather than looking at children and widget state.
setHexpandSet
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets whether the hexpand flag (see widgetGetHexpand
) will
be used.
The hexpand-set property will be set automatically when you call
widgetSetHexpand
to set hexpand, so the most likely
reason to use this function would be to unset an explicit expand
flag.
If hexpand is set, then it overrides any computed expand value based on child widgets. If hexpand is not set, then the expand value depends on whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here for completeness and consistency.
setMapped
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Marks the widget as being mapped.
This function should only ever be called in a derived widget's “map” or “unmap” implementation.
Since: 2.20
setMarginBottom
widgetSetMarginBottom Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Int32 |
|
-> m () |
Sets the bottom margin of widget
.
See the Widget
:margin-bottom
property.
Since: 3.0
setMarginEnd
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Int32 |

:margin-end
property.
Since: 3.12
setMarginLeft
:: (HasCallStack, MonadIO m, IsWidget a) | |

:margin-top
property.
Since: 3.0
setName
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Text |
|
-> m () |
Widgets can be named, which allows you to refer to them from a
CSS file. You can apply a style to widgets with a particular name
in the CSS file. See the documentation for the CSS syntax (on the
same page as the docs for StyleContext
).
Note that the CSS syntax has certain special characters to delimit and represent elements in a selector (period, #, >, *...), so using these will make your widget impossible to match by name. Any combination of alphanumeric symbols, dashes and underscores will suffice.
setNoShowAll
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets the Widget
:no-show-all
property, which determines whether
calls to widgetShowAll
will affect this widget.
This is mostly for use in constructing widget hierarchies with externally
controlled visibility, see UIManager
.
Since: 2.4
setOpacity
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Double |
|
-> m () |
Request the widget
to be rendered partially transparent,
with opacity 0 being fully transparent and 1 fully opaque. (Opacity values
are clamped to the [0,1] range.).
This works on both toplevel widget, and child widgets, although there
are some limitations:
For toplevel widgets this depends on the capabilities of the windowing
system. On X11 this has any effect only on X screens with a compositing manager
running. See widgetIsComposited
. On Windows it should work
always, although setting a window’s opacity after the window has been
shown causes it to flicker once on Windows.
For child widgets it doesn’t work if any affected widget has a native window, or disables double buffering.
Since: 3.8
setParent
:: (HasCallStack, MonadIO m, IsWidget a, IsWidget b) | |
=> a |
|
-> b |
|
-> m () |
This function is useful only when implementing subclasses of
Container
.
Sets the container as the parent of widget
, and takes care of
some details such as updating the state and style of the child
to reflect its new location. The opposite function is
widgetUnparent
.
setParentWindow
widgetSetParentWindow Source #
:: (HasCallStack, MonadIO m, IsWidget a, IsWindow b) | |
=> a |
|
-> b |
|
-> m () |
setRealized
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Marks the widget as being realized. This function must only be
called after all GdkWindows
for the widget
have been created
and registered.
This function should only ever be called in a derived widget's “realize” or “unrealize” implementation.
Since: 2.20
setReceivesDefault
widgetSetReceivesDefault Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Specifies whether widget
will be treated as the default widget
within its toplevel when it has the focus, even if another widget
is the default.
See widgetGrabDefault
for details about the meaning of
“default”.
Since: 2.18
setRedrawOnAllocate
widgetSetRedrawOnAllocate Source #
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets whether the entire widget is queued for drawing when its size
allocation changes. By default, this setting is True
and
the entire widget is redrawn on every size change. If your widget
leaves the upper left unchanged when made bigger, turning this
setting off will improve performance.
Note that for widgets where widgetGetHasWindow
is False
setting this flag to False
turns off all allocation on resizing:
the widget will not even redraw if its position changes; this is to
allow containers that don’t draw anything to avoid excess
invalidations. If you set this flag on a widget with no window that
does draw on widget
->window, you are
responsible for invalidating both the old and new allocation of the
widget when the widget is moved and responsible for invalidating
regions newly when the widget increases size.
setSensitive
:: (HasCallStack, MonadIO m, IsWidget a) | |
=> a |
|
-> Bool |
|
-> m () |
Sets the sensitivity of a widget. A widget is sensitive if the user can interact with it. Insensitive widgets are “grayed out” and the user can’t interact with them. Insensitive widgets are known as “inactive”, “disabled”, or “ghosted” in some other toolkits.
