### Class

# GtkPopoverMenu

#### Description [src]

    final class Gtk.PopoverMenu : Gtk.Popover
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget, Gtk.Native, Gtk.ShortcutManager {
      /* No available fields */
    }

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

`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 `gtk_popover_menu_new_from_model()`. If you need to put other widgets such as a `GtkSpinButton` or a `GtkSwitch` into a popover, you can use `gtk_popover_menu_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.

    <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 `GtkBuilder` 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
- “use-markup”: whether the text in the menu item includes Pango markup
- “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 track whether a submenu is open
- “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 `gtk_application_set_menubar()`.
- “custom”: a string used to match against the ID of a custom child added with `gtk_popover_menu_add_child()`, `gtk_popover_menu_bar_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 `gtk_application_set_accels_for_action()`, `gtk_widget_class_add_binding_action()` or `gtk_shortcut_controller_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.
