public class PopoverMenu : Popover, Accessible, Buildable, ConstraintTarget, Native, ShortcutManager

`GtkPopoverMenu` is a subclass of `GtkPopover` that implements menu behavior.

![An example GtkPopoverMenu](menu.png)

`GtkPopoverMenu` treats its children like menus and allows switching between them. It can open submenus as traditional, nested submenus, or in a more touch-friendly sliding fashion.

`GtkPopoverMenu` is meant to be used primarily with menu models, using [ctor@Gtk.PopoverMenu.new_from_model]. If you need to put other widgets such as a `GtkSpinButton` or a `GtkSwitch` into a popover, you can use [method@Gtk.PopoverMenu.add_child].

For more dialog-like behavior, use a plain `GtkPopover`.

Menu models

The XML format understood by `GtkBuilder` for `GMenuModel` consists of a toplevel `<menu>` element, which contains one or more `<item >` elements. Each `<item>` element contains `<attribute>` and `<link>` elements with a mandatory name attribute. `<link >` elements have the same content model as `<menu>`. Instead of `<link name="submenu>` or `<link name="section">`, you can use `<submenu>` or `<section>` elements.

```xml <menu id='app-menu'> <section> <item> <attribute name='label' translatable='yes'>_New Window</attribute > <attribute name='action'>app.new</attribute> </item> <item> <attribute name='label' translatable='yes'> _About Sunny</attribute> <attribute name='action'>app.about</attribute> </item> <item> <attribute name='label' translatable='yes'>_Quit</attribute> <attribute name='action'>app.quit</attribute> </item> < /section> </menu> ```

Attribute values can be translated using gettext, like other `GtkBuilder` content. `<attribute>` elements can be marked for translation with a `translatable="yes"` attribute. It is also possible to specify message context and translator comments, using the context and comments attributes. To make use of this, the Builder must have been given the gettext domain to use.

The following attributes are used when constructing menu items:

  • "label": a user-visible string to display
  • "action": the prefixed name of the action to trigger
  • "target": the parameter to use when activating the action
  • "icon" and "verb-icon": names of icons that may be displayed
  • "submenu-action": name of an action that may be used to determine if a submenu can be opened
  • "hidden-when": a string used to determine when the item will be hidden. Possible values include "action-disabled", "action-missing", "macos-menubar". This is mainly useful for exported menus, see [method@Gtk.Application.set_menubar].
  • "custom": a string used to match against the ID of a custom child added with [method@Gtk.PopoverMenu.add_child], [ method@Gtk.PopoverMenuBar.add_child], or in the ui file with `<child type="ID">`.

The following attributes are used when constructing sections:

  • "label": a user-visible string to use as section heading
  • "display-hint": a string used to determine special formatting for the section. Possible values include "horizontal-buttons", "circular-buttons" and "inline-buttons". They all indicate that section should be displayed as a horizontal row of buttons.
  • "text-direction": a string used to determine the `GtkTextDirection` to use when "display-hint" is set to "horizontal-buttons". Possible values include "rtl", "ltr", and "none".

The following attributes are used when constructing submenus:

  • "label": a user-visible string to display
  • "icon": icon name to display

Menu items will also show accelerators, which are usually associated with actions via [method@Gtk.Application.set_accels_for_action], [ id@gtk_widget_class_add_binding_action] or [method@Gtk.ShortcutController.add_shortcut].

CSS Nodes

`GtkPopoverMenu` is just a subclass of `GtkPopover` that adds custom content to it, therefore it has the same CSS nodes. It is one of the cases that add a .menu style class to the popover's main node.

Accessibility

`GtkPopoverMenu` uses the gtk_accessible_role_menu role, and its items use the gtk_accessible_role_menu_item, gtk_accessible_role_menu_item_checkbox or gtk_accessible_role_menu_item_radio roles, depending on the action they are connected to.
