PopoverMenuRef

public struct PopoverMenuRef : PopoverMenuProtocol, GWeakCapturing

GtkPopoverMenu is a subclass of GtkPopover that treats its children like menus and allows switching between them. It is meant to be used primarily together with GtkModelButton, but any widget can be used, such as GtkSpinButton or GtkScale. In this respect, GtkPopoverMenu is more flexible than popovers that are created from a GMenuModel with gtk_popover_new_from_model().

To add a child as a submenu, set the GtkPopoverMenu:submenu child property to the name of the submenu. To let the user open this submenu, add a GtkModelButton whose GtkModelButton:menu-name property is set to the name you’ve given to the submenu.

By convention, the first child of a submenu should be a GtkModelButton to switch back to the parent menu. Such a button should use the GtkModelButton:inverted and GtkModelButton:centered properties to achieve a title-like appearance and place the submenu indicator at the opposite side. To switch back to the main menu, use “main” as the menu name.

Example

<object class="GtkPopoverMenu">
  <child>
    <object class="GtkBox">
      <property name="visible">True</property>
      <property name="margin">10</property>
      <child>
        <object class="GtkModelButton">
          <property name="visible">True</property>
          <property name="action-name">win.frob</property>
          <property name="text" translatable="yes">Frob</property>
        </object>
      </child>
      <child>
        <object class="GtkModelButton">

          <property name="menu-name">more</property>
          <property name="text" translatable="yes">More</property>
        </object>

          <property name="text" translatable="yes">Bar</property>

Just like normal popovers created using gtk_popover_new_from_model, GtkPopoverMenu instances have a single css node called “popover” and get the .menu style class.

The PopoverMenuRef type acts as a lightweight Swift reference to an underlying GtkPopoverMenu instance. It exposes methods that can operate on this data type through PopoverMenuProtocol conformance. Use PopoverMenuRef only as an unowned reference to an existing GtkPopoverMenu instance.
