public class PopoverMenuBar extends Widget
`GtkPopoverMenuBar` presents a horizontal bar of items that pop
up popover menus when clicked.

![An example GtkPopoverMenuBar](menubar.png)

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.
