## Description

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 “submenu” child property to the name of the submenu. To let the user open this submenu, add a GtkModelButton whose “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 “inverted” and “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.

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.

## Functions

### gtk_popover_menu_new ()

    GtkWidget *
    gtk_popover_menu_new (void);

Creates a new popover menu.

#### Returns

a new GtkPopoverMenu

Since: 3.16

### gtk_popover_menu_open_submenu ()

    void
    gtk_popover_menu_open_submenu (GtkPopoverMenu *popover,
                                   const gchar *name);

Opens a submenu of the `popover` . The `name` must be one of the names given to the submenus of `popover` with “submenu”, or "main" to switch back to the main menu.

GtkModelButton will open submenus automatically when the “menu-name” property is set, so this function is only needed when you are using other kinds of widgets to initiate menu changes.

#### Parameters

popover | a GtkPopoverMenu |
name | the name of the menu to switch to |

Since: 3.16
