The contents of popover are removed and then refilled with menu items
according to model. When model changes, popover is updated.
Calling this function twice on popover with different model will
cause the first binding to be replaced with a binding to the new
model. If model is NULL then any previous binding is undone and
all children are removed.
If action_namespace is non-NULL then the effect is as if all
actions mentioned in the model have their names prefixed with the
namespace, plus a dot. For example, if the action “quit” is
mentioned and action_namespace is “app” then the effective action
name is “app.quit”.
This function uses GtkActionable to define the action name and
target values on the created menu items. If you want to use an
action group other than “app” and “win”, or if you want to use a
gtk.MenuShell outside of a gtk.ApplicationWindow, then you will need
to attach your own action group to the widget hierarchy using
Widget.insertActionGroup. As an example, if you created a
group with a “quit” action and inserted it with the name “mygroup”
then you would use the action name “mygroup.quit” in your
gio.MenuModel
