windowNewPopup :: IO WindowSource
Create a popup window.
Methods
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Activates the current focused widget within the window.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Activates the default widget for the window, unless the current focused
widget has been configured to receive the default action (see
ReceivesDefault in WidgetFlags), in which case the focused widget is
activated.
Arguments
| :: WindowClass self | |
| => self | |
| -> Int |
|
| -> Int |
|
| -> IO () |
Sets the default size of a window. If the window's "natural" size (its
size request) is larger than the default, the default will be ignored. More
generally, if the default size does not obey the geometry hints for the
window (windowSetGeometryHints can be used to set these explicitly), the
default size will be clamped to the nearest permitted size.
Unlike widgetSetSizeRequest, which sets a size request for a widget and
thus would keep users from shrinking the window, this function only sets the
initial size, just as if the user had resized the window themselves. Users
can still shrink the window again as they normally would. Setting a default
size of -1 means to use the "natural" default size (the size request of
the window).
For more control over a window's initial size and how resizing works,
investigate windowSetGeometryHints.
For some uses, windowResize is a more appropriate function.
windowResize changes the current size of the window, rather than the size
to be used on initial display. windowResize always affects the window
itself, not the geometry widget.
The default size of a window only affects the first time a window is shown; if a window is hidden and re-shown, it will remember the size it had prior to hiding, rather than using the default size.
Windows can't actually be 0x0 in size, they must be at least 1x1, but
passing 0 for width and height is OK, resulting in a 1x1 default size.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Int, Int) |
|
Gets the default size of the window. A value of -1 for the width or height indicates that a default size has not been explicitly set for that dimension, so the "natural" size of the window will be used.
windowSetPosition :: WindowClass self => self -> WindowPosition -> IO ()Source
Sets a position constraint for this window. If the old or new constraint
is WinPosCenterAlways, this will also cause the window to be repositioned
to satisfy the new constraint.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Returns whether the window is part of the current active toplevel. (That
is, the toplevel window receiving keystrokes.) The return value is True if
the window is active toplevel itself, but also if it is, say, a Plug
embedded in the active toplevel. You might use this function if you wanted
to draw a widget differently in an active window from a widget in an
inactive window. See windowHasToplevelFocus
- Available since Gtk+ version 2.4
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Returns whether the input focus is within this Window. For real
toplevel windows, this is identical to windowIsActive, but for embedded
windows, like Plug, the results will differ.
- Available since Gtk+ version 2.4
windowListToplevels :: IO [Window]Source
Returns a list of all existing toplevel windows.
windowSetDefault :: (WindowClass self, WidgetClass widget) => self -> Maybe widget -> IO ()Source
The default widget is the widget that's activated when the user presses
Enter in a dialog (for example). This function sets or unsets the default
widget for a Window about. When setting (rather than unsetting) the
default widget it's generally easier to call widgetGrabDefault on the
widget. Before making a widget the default widget, you must set the
widgetCanDefault flag on the widget.
windowGetDefaultWidget :: WindowClass self => self -> IO (Maybe Widget)Source
Returns the default widget for window. See windowSetDefault for more details.
- Available since Gtk+ version 2.14
Arguments
| :: (WindowClass self, WidgetClass widget) | |
| => self | |
| -> KeyVal |
|
| -> widget |
|
| -> IO () |
Adds a mnemonic to this window.
Arguments
| :: (WindowClass self, WidgetClass widget) | |
| => self | |
| -> KeyVal |
|
| -> widget |
|
| -> IO () |
Removes a mnemonic from this window.
Arguments
| :: WindowClass self | |
| => self | |
| -> KeyVal |
|
| -> [Modifier] |
|
| -> IO Bool | return |
Activates the targets associated with the mnemonic.
Arguments
| :: WindowClass self | |
| => self | |
| -> EventM EKey Bool | return |
Activates mnemonics and accelerators for this Window.
This is normally called by the default keyPressEvent handler for toplevel windows,
however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.
Arguments
| :: WindowClass self | |
| => self | |
| -> EventM EKey Bool | return |
Propagate a key press or release event to the focus widget and up the focus container chain until a widget handles event.
This is normally called by the default keyPressEvent and keyReleaseEvent handlers for toplevel windows,
however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.
windowPresent :: WindowClass self => self -> IO ()Source
Presents a window to the user. This may mean raising the window in the stacking order, deiconifying it, moving it to the current desktop, and/or giving it the keyboard focus, possibly dependent on the user's platform, window manager, and preferences.
If window is hidden, this function calls widgetShow as well.
This function should be used when the user tries to open a window that's
already open. Say for example the preferences dialog is currently open, and
the user chooses Preferences from the menu a second time; use
windowPresent to move the already-open dialog where the user can see it.
If you are calling this function in response to a user interaction, it is
preferable to use windowPresentWithTime.
windowDeiconify :: WindowClass self => self -> IO ()Source
Asks to deiconify (i.e. unminimize) the specified window. Note that you
shouldn't assume the window is definitely deiconified afterward, because
other entities (e.g. the user or window manager) could iconify it again
before your code which assumes deiconification gets to run.
You can track iconification via the windowStateEvent signal on
Widget.
windowIconify :: WindowClass self => self -> IO ()Source
Asks to iconify (i.e. minimize) the specified window. Note that you
shouldn't assume the window is definitely iconified afterward, because other
entities (e.g. the user or window manager) could deiconify it again, or
there may not be a window manager in which case iconification isn't
possible, etc. But normally the window will end up iconified. Just don't
write code that crashes if not.
It's permitted to call this function before showing a window, in which case the window will be iconified before it ever appears onscreen.
You can track iconification via the windowStateEvent signal on
Widget.
windowMaximize :: WindowClass self => self -> IO ()Source
Asks to maximize the window, so that it becomes full-screen. Note that you shouldn't assume the window is definitely maximized afterward, because other entities (e.g. the user or window manager) could unmaximize it again, and not all window managers support maximization. But normally the window will end up maximized. Just don't write code that crashes if not.
It's permitted to call this function before showing a window, in which case the window will be maximized when it appears onscreen initially.
You can track maximization via the windowStateEvent signal on
Widget.
windowUnmaximize :: WindowClass self => self -> IO ()Source
Asks to unmaximize the window. Note that you shouldn't assume the window is definitely unmaximized afterward, because other entities (e.g. the user or window manager) could maximize it again, and not all window managers honor requests to unmaximize. But normally the window will end up unmaximized. Just don't write code that crashes if not.
You can track maximization via the windowStateEvent signal on
Widget.
windowFullscreen :: WindowClass self => self -> IO ()Source
Asks to place window in the fullscreen state. Note that you shouldn't
assume the window is definitely full screen afterward, because other
entities (e.g. the user or window manager) could unfullscreen it again, and
not all window managers honor requests to fullscreen windows. But normally
the window will end up fullscreen. Just don't write code that crashes if
not.
You can track the fullscreen state via the windowStateEvent signal
on Widget.
- Available since Gtk+ version 2.2
windowUnfullscreen :: WindowClass self => self -> IO ()Source
Asks to toggle off the fullscreen state for window. Note that you
shouldn't assume the window is definitely not full screen afterward, because
other entities (e.g. the user or window manager) could fullscreen it again,
and not all window managers honor requests to unfullscreen windows. But
normally the window will end up restored to its normal state. Just don't
write code that crashes if not.
You can track the fullscreen state via the windowStateEvent signal
on Widget.
- Available since Gtk+ version 2.2
Arguments
| :: WindowClass self | |
| => self | |
| -> Bool |
|
| -> IO () |
Asks to keep window above, so that it stays on top. Note that you
shouldn't assume the window is definitely above afterward, because other
entities (e.g. the user or window manager) could not keep it above, and not
all window managers support keeping windows above. But normally the window
will end kept above. Just don't write code that crashes if not.
It's permitted to call this function before showing a window, in which case the window will be kept above when it appears onscreen initially.
You can track the above state via the windowStateEvent signal on
Widget.
Note that, according to the Extended Window Manager Hints specification, the above state is mainly meant for user preferences and should not be used by applications e.g. for drawing attention to their dialogs.
- Available since Gtk+ version 2.4
Arguments
| :: WindowClass self | |
| => self | |
| -> Bool |
|
| -> IO () |
Asks to keep window below, so that it stays in bottom. Note that you
shouldn't assume the window is definitely below afterward, because other
entities (e.g. the user or window manager) could not keep it below, and not
all window managers support putting windows below. But normally the window
will be kept below. Just don't write code that crashes if not.
It's permitted to call this function before showing a window, in which case the window will be kept below when it appears onscreen initially.
You can track the below state via the windowStateEvent signal on
Widget.
Note that, according to the Extended Window Manager Hints specification, the above state is mainly meant for user preferences and should not be used by applications e.g. for drawing attention to their dialogs.
- Available since Gtk+ version 2.4
windowSetStartupId :: WindowClass self => self -> String -> IO ()Source
Startup notification identifiers are used by desktop environment to track application startup,
to provide user feedback and other features. This function changes the corresponding property on the underlying GdkWindow.
Normally, startup identifier is managed automatically and you should only use this function in special cases like transferring focus from other processes. You should use this function before calling windowPresent or any equivalent function generating a window map event.
This function is only useful on X11, not with other GTK+ targets.
- Available since Gtk+ version 2.12
windowGetFrame :: WindowClass widget => widget -> IO (Maybe DrawWindow)Source
Retrieves the frame DrawWindow that contains a Window.
windowSetFrameDimensionsSource
Arguments
| :: WindowClass self | |
| => self | |
| -> Int |
|
| -> Int |
|
| -> Int |
|
| -> Int |
|
| -> IO () |
(Note: this is a special-purpose function intended for the framebuffer
port; see windowSetHasFrame. It will have no effect on the window border
drawn by the window manager, which is the normal case when using the X
Window system.)
For windows with frames (see windowSetHasFrame) this function can be
used to change the size of the frame border.
windowGetFrameDimensionsSource
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Int, Int, Int, Int) | returns |
Retrieves the dimensions of the frame window for this toplevel. See
windowSetHasFrame, windowSetFrameDimensions.
(Note: this is a special-purpose function intended for the framebuffer port;
see windowSetHasFrame.
It will not return the size of the window border drawn by the window manager,
which is the normal case when using a windowing system.
See drawWindowGetFrameExtents to get the standard window border extents.)
windowStick :: WindowClass self => self -> IO ()Source
Asks to stick window, which means that it will appear on all user
desktops. Note that you shouldn't assume the window is definitely stuck
afterward, because other entities (e.g. the user or window manager) could
unstick it again, and some window managers do not support sticking windows.
But normally the window will end up stuck. Just don't write code that
crashes if not.
It's permitted to call this function before showing a window.
You can track stickiness via the windowStateEvent signal on
Widget.
windowUnstick :: WindowClass self => self -> IO ()Source
Asks to unstick window, which means that it will appear on only one of
the user's desktops. Note that you shouldn't assume the window is definitely
unstuck afterward, because other entities (e.g. the user or window manager)
could stick it again. But normally the window will end up stuck. Just don't
write code that crashes if not.
You can track stickiness via the windowStateEvent signal on
Widget.
Arguments
| :: WindowClass self | |
| => self | |
| -> AccelGroup |
|
| -> IO () |
Associate accelGroup with window, such that calling
accelGroupsActivate on window will activate accelerators in
accelGroup.
Arguments
| :: WindowClass self | |
| => self | |
| -> AccelGroup |
|
| -> IO () |
Reverses the effects of windowAddAccelGroup.
windowSetDefaultIconList :: [Pixbuf] -> IO ()Source
Sets an icon list to be used as fallback for windows that haven't had windowSetIconList called on them to set up a window-specific icon list.
This function allows you to set up the icon for all windows in your app at once.
See windowSetIconList for more details.
windowGetDefaultIconList :: IO [Pixbuf]Source
Gets the value set by windowSetDefaultIconList.
windowSetDefaultIcon :: Maybe Pixbuf -> IO ()Source
Sets an icon to be used as fallback for windows that haven't had windowSetIcon called on them from a pixbuf.
- Available since Gtk+ version 2.4
windowSetDefaultIconFromFileSource
Arguments
| :: String |
|
| -> IO Bool | returns |
Sets an icon to be used as fallback for windows that haven't had
windowSetIconList called on them from a file on disk. May throw a GError if
the file cannot be loaded.
- Available since Gtk+ version 2.2
windowSetDefaultIconNameSource
Sets an icon to be used as fallback for windows that haven't had
windowSetIconList called on them from a named themed icon, see
windowSetIconName.
- Available since Gtk+ version 2.6
windowGetDefaultIconNameSource
Returns the fallback icon name for windows that has been set with
windowSetDefaultIconName.
- Available since Gtk+ version 2.16
Arguments
| :: WindowClass self | |
| => self | |
| -> Gravity |
|
| -> IO () |
Window gravity defines the meaning of coordinates passed to windowMove.
See windowMove and Gravity for more details.
The default window gravity is GravityNorthWest which will typically
"do what you mean."
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Gravity | returns window gravity |
Gets the value set by windowSetGravity.
Arguments
| :: WindowClass self | |
| => self | |
| -> Screen |
|
| -> IO () |
Sets the Screen where the window is displayed; if the window is
already mapped, it will be unmapped, and then remapped on the new screen.
- Available since Gtk+ version 2.2
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Screen | returns a |
Returns the Screen associated with the window.
- Available since Gtk+ version 2.2
Arguments
| :: WindowClass self | |
| => self | |
| -> WindowEdge |
|
| -> MouseButton |
|
| -> Int |
|
| -> Int |
|
| -> TimeStamp |
|
| -> IO () |
Starts resizing a window. This function is used if an application has window resizing controls. When GDK can support it, the resize will be done using the standard mechanism for the window manager or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.
Arguments
| :: WindowClass self | |
| => self | |
| -> MouseButton |
|
| -> Int |
|
| -> Int |
|
| -> TimeStamp |
|
| -> IO () |
Starts moving a window. This function is used if an application has window movement grips. When GDK can support it, the window movement will be done using the standard mechanism for the window manager or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.
Arguments
| :: WindowClass self | |
| => self | |
| -> WindowTypeHint |
|
| -> IO () |
By setting the type hint for the window, you allow the window manager to decorate and handle the window in a way which is suitable to the function of the window in your application.
This function should be called before the window becomes visible.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO WindowTypeHint | returns the type hint for |
Gets the type hint for this window. See windowSetTypeHint.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Maybe Pixbuf) | returns icon for window, or |
Gets the value set by windowSetIcon (or if you've called
windowSetIconList, gets the first icon in the icon list).
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Int, Int) |
|
This function returns the position you need to pass to windowMove to
keep window in its current position. This means that the meaning of the
returned value varies with window gravity. See windowMove for more
details.
If you haven't changed the window gravity, its gravity will be
GravityNorthWest. This means that windowGetPosition gets the position of
the top-left corner of the window manager frame for the window. windowMove
sets the position of this same top-left corner.
Moreover, nearly all window managers are historically broken with respect
to their handling of window gravity. So moving a window to its current
position as returned by windowGetPosition tends to result in moving the
window slightly. Window managers are slowly getting better over time.
If a window has gravity GravityStatic the window manager frame is not
relevant, and thus windowGetPosition will always produce accurate results.
However you can't use static gravity to do things like place a window in a
corner of the screen, because static gravity ignores the window manager
decorations.
If you are saving and restoring your application's window positions, you should know that it's impossible for applications to do this without getting it somewhat wrong because applications do not have sufficient knowledge of window manager state. The Correct Mechanism is to support the session management protocol (see the "GnomeClient" object in the GNOME libraries for example) and allow the window manager to save your window sizes and positions.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Int, Int) | (width, height) |
Obtains the current size of the window. If the window is not onscreen, it
returns the size Gtk+ will suggest to the window manager for the initial
window size (but this is not reliably the same as the size the window
manager will actually select). The size obtained by windowGetSize is the
last size received in a EventConfigure, that is,
Gtk+ uses its locally-stored size, rather than querying the X server for the
size. As a result, if you call windowResize then immediately call
windowGetSize, the size won't have taken effect yet. After the window
manager processes the resize request, Gtk+ receives notification that the
size has changed via a configure event, and the size of the window gets
updated.
Note 1: Nearly any use of this function creates a race condition, because
the size of the window may change between the time that you get the size and
the time that you perform some action assuming that size is the current
size. To avoid race conditions, connect to "configure_event" on the window
and adjust your size-dependent state to match the size delivered in the
EventConfigure.
Note 2: The returned size does not include the size of the window manager decorations (aka the window frame or border). Those are not drawn by Gtk+ and Gtk+ has no reliable method of determining their size.
Note 3: If you are getting a window size in order to position the window
onscreen, there may be a better way. The preferred way is to simply set the
window's semantic type with windowSetTypeHint, which allows the window
manager to e.g. center dialogs. Also, if you set the transient parent of
dialogs with windowSetTransientFor window managers will often center the
dialog over its parent window. It's much preferred to let the window manager
handle these things rather than doing it yourself, because all apps will
behave consistently and according to user prefs if the window manager
handles it. Also, the window manager can take the size of the window
decorations/border into account, while your application cannot.
In any case, if you insist on application-specified window positioning,
there's still a better way than doing it yourself - windowSetPosition
will frequently handle the details for you.
Arguments
| :: WindowClass self | |
| => self | |
| -> Int |
|
| -> Int |
|
| -> IO () |
Asks the window manager to move window to the given position. Window
managers are free to ignore this; most window managers ignore requests for
initial window positions (instead using a user-defined placement algorithm)
and honor requests after the window has already been shown.
Note: the position is the position of the gravity-determined reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is positioned at the reference point.
By default the gravity is GravityNorthWest, so the reference point is
simply the x, y supplied to windowMove. The top-left corner of the
window decorations (aka window frame or border) will be placed at x, y.
Therefore, to position a window at the top left of the screen, you want to
use the default gravity (which is GravityNorthWest) and move the window to
0,0.
To position a window at the bottom right corner of the screen, you would
set GravitySouthEast, which means that the reference point is at x + the
window width and y + the window height, and the bottom-right corner of the
window border will be placed at that reference point. So, to place a window
in the bottom right corner you would first set gravity to south east, then
write: gtk_window_move (window, gdk_screen_width() - window_width,
gdk_screen_height() - window_height).
The Extended Window Manager Hints specification at http://www.freedesktop.org/Standards/wm-spec has a nice table of gravities in the "implementation notes" section.
The windowGetPosition documentation may also be relevant.
windowParseGeometry :: WindowClass self => self -> String -> IO BoolSource
Parses a standard X Window System geometry string - see the manual page for X (type 'man X') for details on this.
windowParseGeometry does work on all GTK+ ports including Win32 but is primarily intended for an X environment.
If either a size or a position can be extracted from the geometry string,
windowParseGeometry returns True and calls gtk_window_set_default_size() andor gtk_window_move() to resizemove the window.
If windowParseGeometry returns True,
it will also set the HintUserPos andor 'HintUserSize' hints indicating to the window manager that the sizeposition of the window was user-specified
This causes most window managers to honor the geometry.
Note that for windowParseGeometry to work as expected, it has to be called when the window has its final size, i.e.
after calling widgetShowAll on the contents and windowSetGeometryHints on the window.
windowReshowWithInitialSize :: WindowClass self => self -> IO ()Source
Hides window, then reshows it, resetting the default size and position of the window. Used by GUI builders only.
Arguments
| :: WindowClass self | |
| => self | |
| -> Int |
|
| -> Int |
|
| -> IO () |
Resizes the window as if the user had done so, obeying geometry
constraints. The default geometry constraint is that windows may not be
smaller than their size request; to override this constraint, call
widgetSetSizeRequest to set the window's request to a smaller value.
If windowResize is called before showing a window for the first time,
it overrides any default size set with windowSetDefaultSize.
Windows may not be resized smaller than 1 by 1 pixels.
Arguments
| :: WindowClass self | |
| => self | |
| -> FilePath |
|
| -> IO () |
Sets the icon for window.
This function is equivalent to calling windowSetIcon with a pixbuf
created by loading the image from filename.
This may throw an exception if the file cannot be loaded.
- Available since Gtk+ version 2.2
windowSetAutoStartupNotificationSource
By default, after showing the first Window for each Screen, Gtk+
calls screenNotifyStartupComplete. Call this function to disable the
automatic startup notification. You might do this if your first window is a
splash screen, and you want to delay notification until after your real main
window has been shown, for example.
In that example, you would disable startup notification temporarily, show your splash screen, then re-enable it so that showing the main window would automatically result in notification.
- Available since Gtk+ version 2.2
Arguments
| :: WindowClass self | |
| => self | |
| -> TimeStamp |
|
| -> IO () |
Presents a window to the user in response to a user interaction. If you
need to present a window without a timestamp, use windowPresent. See
windowPresent for details.
- Available since Gtk+ version 2.8
Arguments
| :: (WindowClass self, WidgetClass widget) | |
| => self |
|
| -> Maybe widget |
|
| -> Maybe (Int, Int) |
|
| -> Maybe (Int, Int) |
|
| -> Maybe (Int, Int) |
|
| -> Maybe (Int, Int) |
|
| -> Maybe (Double, Double) |
|
| -> IO () |
This function sets up hints about how a window can be resized by the user. You can set a minimum and maximum size, the allowed resize increments (e.g. for xterm, you can only resize by the size of a character) and aspect ratios.
If you set a geometry widget, the hints will apply to the geometry widget instead of directly to the toplevel window. Of course since the geometry widget is a child widget of the top level window, constraining the sizing behaviour of the widget will have a knock-on effect on the sizing of the toplevel window.
The minWidth/minHeight/maxWidth/maxHeight fields may be set to
-1, to use the size request of the window or geometry widget. If the
minimum size hint is not provided, Gtk+ will use the size requisition of the
window (or the geometry widget if it set) as the minimum size. The base size
is treated similarly.
The canonical use-case for windowSetGeometryHints is to get a terminal
widget to resize properly. Here, the terminal text area should be the
geometry widget. Gtk+ will then automatically set the base size of the
terminal window to the size of other widgets in the terminal window, such as
the menubar and scrollbar. Then, the widthInc and heightInc values
should be set to the size of one character in the terminal. Finally, the
base size should be set to the size of one character. The net effect is that
the minimum size of the terminal will have a 1x1 character terminal area,
and only terminal sizes on the "character grid" will be allowed.
The other useful settings are minAspect and maxAspect. These specify a
width/height ratio as a floating point number. If a geometry widget is set,
the aspect applies to the geometry widget rather than the entire window. The
most common use of these hints is probably to set minAspect and
maxAspect to the same value, thus forcing the window to keep a constant
aspect ratio.

details about window gravity.
Default value: GravityNorthWest
windowToplevelFocus :: WindowClass self => Attr self BoolSource
Whether the input focus is within this GtkWindow.
Note: If add window before HasToplevelFocus (has-toplevel-focus attribute)
will conflicts with fucntion windowHasToplevelFocus, so we named this attribute
to windowToplevelFocus.
Default values: False
windowTransientFor :: (WindowClass self, WindowClass parent) => ReadWriteAttr self (Maybe Window) parentSource
'transientFor' property. See windowGetTransientFor and
windowSetTransientFor
windowFocus :: WindowClass self => Attr self (Maybe Widget)Source
If focus is not the current focus widget, and is focusable, sets it as
the focus widget for the window. If focus is Nothing, unsets the focus widget for
this window. To set the focus to a particular widget in the toplevel, it is
usually more convenient to use widgetGrabFocus instead of this function.
windowHasFrame :: WindowClass self => Attr self BoolSource
(Note: this is a special-purpose function for the framebuffer port, that
causes Gtk+ to draw its own window border. For most applications, you want
windowSetDecorated instead, which tells the window manager whether to draw
the window border.)
If this function is called on a window with setting of True, before it
is realized or showed, it will have a "frame" window around
its DrawWindow, accessible using windowGetFrame. Using the signal
windowFrameEvent you can receive all events targeted at the frame.
This function is used by the 1 -fb port to implement managed windows, but it could conceivably be used by X-programs that want to do their own window decorations.
windowIconList :: WindowClass self => Attr self [Pixbuf]Source
Sets up the icon representing a Window. The icon is used when the
window is minimized (also known as iconified). Some window managers or
desktop environments may also place it in the window frame, or display it in
other contexts.
By passing several sizes, you may improve the final image quality of the icon, by reducing or eliminating automatic image scaling.
Recommended sizes to provide: 16x16, 32x32, 48x48 at minimum, and larger images (64x64, 128x128) if you have them.
See also windowSetDefaultIconList to set the icon for all windows in
your application in one go.
Note that transient windows (those who have been set transient for
another window using windowSetTransientFor) will inherit their icon from
their transient parent. So there's no need to explicitly set the icon on
transient windows.
windowMnemonicModifier :: WindowClass self => Attr self [Modifier]Source
The mnemonic modifier for this window.
windowMnemonicVisible :: WindowClass self => Attr self BoolSource
Signals
frameEvent :: WindowClass self => Signal self (EventM EAny Bool)Source
Observe events that are emitted on the frame of this window.
keysChanged :: WindowClass self => Signal self (IO ())Source
The keysChanged signal gets emitted when the set of accelerators or mnemonics that are associated with window changes.
setFocus :: WindowClass self => Signal self (Maybe Widget -> IO ())Source
Observe a change in input focus.
Deprecated
windowSetTitle :: WindowClass self => self -> String -> IO ()Source
Sets the title of the Window. The title of a window will be displayed
in its title bar; on the X Window System, the title bar is rendered by the
window manager, so exactly how the title appears to users may vary according
to a user's exact configuration. The title should help a user distinguish
this window from other windows they may have open. A good title might
include the application name and current document filename, for example.
windowGetTitle :: WindowClass self => self -> IO StringSource
Retrieves the title of the window. See windowSetTitle.
windowSetResizable :: WindowClass self => self -> Bool -> IO ()Source
Sets whether the user can resize a window. Windows are user resizable by default.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Gets the value set by windowSetResizable.
Arguments
| :: WindowClass self | |
| => self | |
| -> Bool |
|
| -> IO () |
Sets a window modal or non-modal. Modal windows prevent interaction with
other windows in the same application. To keep modal dialogs on top of main
application windows, use windowSetTransientFor to make the dialog
transient for the parent; most window managers will then disallow lowering
the dialog below the parent.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Returns whether the window is modal. See windowSetModal.
windowSetPolicy :: WindowClass self => self -> Bool -> Bool -> Bool -> IO ()Source
Deprecated: Use windowSetResizable instead.
Sets the window resizing policy.
- Warning: this function is deprecated and should not be used in
newly-written code. Use
windowSetResizableinstead.
Arguments
| :: (WindowClass self, WindowClass parent) | |
| => self | |
| -> parent |
|
| -> IO () |
Dialog windows should be set transient for the main application window
they were spawned from. This allows window managers to e.g. keep the dialog
on top of the main window, or center the dialog over the main window.
dialogNewWithButtons and other convenience functions in Gtk+ will
sometimes call windowSetTransientFor on your behalf.
On Windows, this function will and put the child window on top of the parent, much as the window manager would have done on X.
Note that if you want to show a window self on top of a full-screen window parent, you need to
turn the self window into a dialog (using windowSetTypeHint with WindowTypeHintDialog).
Otherwise the parent window will always cover the self window.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Maybe Window) | returns the transient parent for this window, or
|
Fetches the transient parent for this window. See
windowSetTransientFor.
windowSetDestroyWithParent :: WindowClass self => self -> Bool -> IO ()Source
If this setting is True, then destroying the transient parent of the
window will also destroy the window itself. This is useful for dialogs that
shouldn't persist beyond the lifetime of the main window they're associated
with, for example.
windowGetDestroyWithParentSource
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Returns whether the window will be destroyed with its transient parent.
See windowSetDestroyWithParent.
windowGetFocus :: WindowClass self => self -> IO (Maybe Widget)Source
Retrieves the current focused widget within the window.
| Note that this is the widget that would have the focus if the toplevel
| window focused; if the toplevel window is not focused then
| widgetHasFocus will not be True for the widget.
windowSetFocus :: (WindowClass self, WidgetClass widget) => self -> Maybe widget -> IO ()Source
If focus is not the current focus widget, and is focusable, sets it as
| the focus widget for the window. If focus is Nothing, unsets the focus
| widget for this window. To set the focus to a particular widget in the
| toplevel, it is usually more convenient to use widgetGrabFocus instead
| of this function.
windowSetMnemonicModifierSource
Arguments
| :: WindowClass self | |
| => self | |
| -> [Modifier] |

| -> IO () |
Sets the mnemonic modifier for this window.
windowGetMnemonicModifierSource
Arguments

windowSetDecorated :: WindowClass self => self -> Bool -> IO ()Source
By default, windows are decorated with a title bar, resize controls, etc.
Some window managers allow Gtk+ to disable these decorations, creating a
borderless window. If you set the decorated property to False using this
function, Gtk+ will do its best to convince the window manager not to
decorate the window. Depending on the system, this function may not have any
effect when called on a window that is already visible, so you should call
it before calling windowShow.
On Windows, this function always works, since there's no window manager policy involved.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO Bool | returns |
Returns whether the window has been set to have decorations such as a
title bar via windowSetDecorated.
Arguments
| :: WindowClass self | |
| => self | |
| -> Bool |
|
| -> IO () |
By default, windows have a close button in the window frame.
Some window managers allow GTK+ to disable this button.
If you set the deletable property to False using this function, GTK+ will do its best to convince the window manager not to show a close button.
Depending on the system, this function may not have any effect when called on a window that is already visible,

Arguments
| :: WindowClass self | |

Accessor for whether the window has a frame window exterior to window->window. Gets the value set by windowSetHasFrame.
Arguments
| :: WindowClass self | |
| => self | |
| -> String |
|
| -> IO () |
This function is only useful on X11, not with other Gtk+ targets.
In combination with the window title, the window role allows a window manager to identify "the same" window when an application is restarted. So for example you might set the "toolbox" role on your app's toolbox window, so that when the user restarts their session, the window manager can put the toolbox back in the same place.
If a window already has a unique title, you don't need to set the role, since the WM can use the title to identify the window when restoring the session.
Arguments
| :: WindowClass self | |
| => self | |
| -> IO (Maybe String) | returns the role of the window if set, or
|
Returns the role of the window. See windowSetRole for further
explanation.
Arguments
| :: WindowClass self | |
| => self | |
| -> Maybe Pixbuf |
|
| -> IO () |
Sets up the icon representing a Window. This icon is used when the
window is minimized (also known as iconified). Some window managers or
desktop environments may also place it in the window frame, or display it in
other contexts.
The icon should be provided in whatever size it was naturally drawn; that is, don't scale the image before passing it to Gtk+. Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.
If you have your icon hand-drawn in multiple sizes, use
windowSetIconList. Then the best size will be used.
This function is equivalent to calling windowSetIconList with a
1-element list.
See also windowSetDefaultIconList to set the icon for all windows in
your application in one go.
windowSetIconList :: WindowClass self => self -> [Pixbuf] -> IO ()Source
Sets up the icon representing a Window. The icon is used when the window is minimized (also known as iconified).
Some window managers or desktop environments may also place it in the window frame, or display it in other contexts.
windowSetIconList allows you to pass in the same icon in several hand-drawn sizes.
The list should contain the natural sizes your icon is available in; that is, don't scale the image before passing it to GTK+.
Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.
By passing several sizes, you may improve the final image quality of the icon, by reducing or eliminating automatic image scaling.
Recommended sizes to provide: 16x16, 32x32, 48x48 at minimum, and larger images (64x64, 128x128) if you have them.
See also windowSetDefaultIconList to set the icon for all windows in your application in one go.
Note that transient windows (those who have been set transient for another window using windowSetTransientFor will inherit their icon from their
transient parent.
So there's no need to explicitly set the icon on transient windows.
windowGetIconList :: WindowClass self => self -> IO [Pixbuf]Source
Retrieves the list of icons set by windowSetIconList.
Arguments
| :: WindowClass self | |
| => self | |
| -> String |
