Creates a gtk.Popover and populates it according to
model. The popover is pointed to the relative_to widget.
The created buttons are connected to actions found in the
gtk.ApplicationWindow to which the popover belongs - typically
by means of being attached to a widget that is contained within
the gtk.ApplicationWindows widget hierarchy.
Actions can also be added using Widget.insertActionGroup
on the menus attach widget or on any of its parent widgets.
