Description

GtkPopover is a bubble-like context window, primarily meant to provide context-dependent information or options. Popovers are attached to a widget, passed at construction time on popoverNew, or updated afterwards through popoverSetRelativeTo, by default they will point to the whole widget area, although this behavior can be changed through popoverSetPointingTo.

The position of a popover relative to the widget it is attached to can also be changed through popoverSetPosition.

By default, Popover performs a GTK+ grab, in order to ensure input events get redirected to it while it is shown, and also so the popover is dismissed in the expected situations (clicks outside the popover, or the Esc key being pressed). If no such modal behavior is desired on a popover, popoverSetModal may be called on it to tweak its behavior.

GtkPopover as menu replacement

GtkPopover is often used to replace menus. To facilitate this, it supports being populated from a MenuModel, using popoverNewFromModel. In addition to all the regular menu model features, this function supports rendering sections in the model in a more compact form, as a row of icon buttons instead of menu items.

To use this rendering, set the ”display-hint” attribute of the section to ”horizontal-buttons” and set the icons of your items with the ”verb-icon” attribute.

<section>
  <attribute name="display-hint">horizontal-buttons</attribute>
  <item>
    <attribute name="label">Cut</attribute>
    <attribute name="action">app.cut</attribute>
    <attribute name="verb-icon">edit-cut-symbolic</attribute>
  </item>
  <item>
    <attribute name="label">Copy</attribute>
    <attribute name="action">app.copy</attribute>
    <attribute name="verb-icon">edit-copy-symbolic</attribute>
  </item>
  <item>
    <attribute name="label">Paste</attribute>
    <attribute name="action">app.paste</attribute>
    <attribute name="verb-icon">edit-paste-symbolic</attribute>
  </item>
</section>

CSS nodes

GtkPopover has a single css node called popover. It always gets the .background style class and it gets the .menu style class if it is menu-like (e.g. PopoverMenu or created using popoverNewFromModel.

Particular uses of GtkPopover, such as touch selection popups or magnifiers in Entry or TextView get style classes like .touch-selection or .magnifier to differentiate from plain popovers.

Methods

Overloaded methods

bindModel

popoverBindModel Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a, IsMenuModel b)
=> a	`popover`: a `Popover`
-> Maybe b	`model`: the `MenuModel` to bind to or `Nothing` to remove binding
-> Maybe Text	`actionNamespace`: the namespace for actions in `model`
-> m ()

Establishes a binding between a Popover and a MenuModel.

The contents of popover are removed and then refilled with menu items according to model. When model changes, popover is updated. Calling this function twice on popover with different model will cause the first binding to be replaced with a binding to the new model. If model is Nothing then any previous binding is undone and all children are removed.

If actionNamespace is non-Nothing then the effect is as if all actions mentioned in the model have their names prefixed with the namespace, plus a dot. For example, if the action “quit” is mentioned and actionNamespace is “app” then the effective action name is “app.quit”.

This function uses Actionable to define the action name and target values on the created menu items. If you want to use an action group other than “app” and “win”, or if you want to use a MenuShell outside of a ApplicationWindow, then you will need to attach your own action group to the widget hierarchy using widgetInsertActionGroup. As an example, if you created a group with a “quit” action and inserted it with the name “mygroup” then you would use the action name “mygroup.quit” in your MenuModel.

new

popoverNew Source #

Arguments

Creates a Popover and populates it according to model. The popover is pointed to the relativeTo widget.

The created buttons are connected to actions found in the ApplicationWindow to which the popover belongs - typically by means of being attached to a widget that is contained within the GtkApplicationWindows widget hierarchy.

Actions can also be added using widgetInsertActionGroup on the menus attach widget or on any of its parent widgets.

Since: 3.12

popdown

popoverPopdown Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`

Since: 3.22

popup

popoverPopup Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`
-> m ()

Pops popover up. This is different than a widgetShow call in that it shows the popover with a transition. If you want to show the popover without a transition, use widgetShow.

Since: 3.22

setConstrainTo

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`
-> PopoverConstraint	`constraint`: the new constraint
-> m ()

Sets a constraint for positioning this popover.

Note that not all platforms support placing popovers freely, and may already impose constraints.

Since: 3.20

setDefaultWidget

popoverSetDefaultWidget Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a, IsWidget b)
=> a	`popover`: a `Popover`
-> Maybe b	`widget`: the new default widget, or `Nothing`

Sets the widget that should be set as default widget while the popover is shown (see windowSetDefault). Popover remembers the previous default widget and reestablishes it when the popover is dismissed.

Since: 3.18

setModal

popoverSetModal Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`
-> Bool	`modal`: `TRUE` to make popover claim all input within the toplevel
-> m ()

Sets whether popover is modal, a modal popover will grab all input within the toplevel and grab the keyboard focus on it when being displayed. Clicking outside the popover area or pressing Esc will dismiss the popover and ungrab input.

Since: 3.12

setPointingTo

popoverSetPointingTo Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`
-> Rectangle	`rect`: rectangle to point to

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`
-> PositionType	`position`: preferred popover position
-> m ()

Sets the preferred position for popover to appear. If the popover is currently visible, it will be immediately updated.

This preference will be respected where possible, although on lack of space (eg. if close to the window edges), the Popover may choose to appear on the opposite side

Since: 3.12

setRelativeTo

popoverSetRelativeTo Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a, IsWidget b)
=> a	`popover`: a `Popover`
-> Maybe b	`relativeTo`: a `Widget`
-> m ()

Sets a new widget to be attached to popover. If popover is visible, the position will be updated.

Note: the ownership of popovers is always given to their relativeTo widget, so if relativeTo is set to Nothing on an attached popover, it will be detached from its previous widget, and consequently destroyed unless extra references are kept.

Since: 3.12

setTransitionsEnabled

popoverSetTransitionsEnabled Source #

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)
=> a	`popover`: a `Popover`
-> Bool	`transitionsEnabled`: Whether transitions are enabled
