PopoverMenuBarProtocol

public protocol PopoverMenuBarProtocol : WidgetProtocol

GtkPopoverMenuBar presents a horizontal bar of items that pop up popover menus when clicked.

An example GtkPopoverMenuBar

The only way to create instances of GtkPopoverMenuBar is from a GMenuModel.

CSS nodes

menubar
├── item[.active]
┊   ╰── popover
╰── item
    ╰── popover

GtkPopoverMenuBar has a single CSS node with name menubar, below which each item has its CSS node, and below that the corresponding popover.

The item whose popover is currently open gets the .active style class.

Accessibility

GtkPopoverMenuBar uses the GTK_ACCESSIBLE_ROLE_MENU_BAR role, the menu items use the GTK_ACCESSIBLE_ROLE_MENU_ITEM role and the menus use the GTK_ACCESSIBLE_ROLE_MENU role.

The PopoverMenuBarProtocol protocol exposes the methods and properties of an underlying GtkPopoverMenuBar instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see PopoverMenuBar. Alternatively, use PopoverMenuBarRef as a lighweight, unowned reference if you already have an instance you just want to use.
