GI.Gtk.Objects.Popover

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.

bindModel

popoverBindModel

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.

Since: 3.12

popdown

popoverPopdown

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)

Arguments

:: (HasCallStack, MonadIO m, IsPopover a)

=> a

popover: a Popover

Since: 3.12

setRelativeTo

popoverSetRelativeTo

Arguments

:: (HasCallStack, MonadIO m, IsPopover a, IsWidget b)
