      <doc xml:space="preserve">#GtkActionMuxer is a #GActionGroup and #GtkActionObservable that is
capable of containing other #GActionGroup instances.

The typical use is aggregating all of the actions applicable to a
particular context into a single action group, with namespacing.

Consider the case of two action groups -- one containing actions
applicable to an entire application (such as 'quit') and one
containing actions applicable to a particular window in the
application (such as 'fullscreen').

In this case, each of these action groups could be added to a
#GtkActionMuxer with the prefixes "app" and "win", respectively.  This
would expose the actions as "app.quit" and "win.fullscreen" on the
#GActionGroup interface presented by the #GtkActionMuxer.

Activations and state change requests on the #GtkActionMuxer are wired
through to the underlying action group in the expected way.

This class is typically only used at the site of "consumption" of
actions (eg: when displaying a menu that contains many actions on
different objects).</doc>

be notified of changes to actions to be notified of those changes.

It is also possible to monitor changes to action groups using
#GObject signals, but there are a number of reasons that this
approach could become problematic:

 - there are four separate signals that must be manually connected
   and disconnected

 - when a large number of different observers wish to monitor a
   (usually disjoint) set of actions within the same action group,
   there is only one way to avoid having all notifications delivered
   to all observers: signal detail.  In order to use signal detail,
   each action name must be quarked, which is not always practical.

 - even if quarking is acceptable, #GObject signal details are
   implemented by scanning a linked list, so there is no real
   decrease in complexity</doc>

      <doc xml:space="preserve">A #GtkMenuTrackerItem is a small helper class used by #GtkMenuTracker to
represent menu items. It has one of three classes: normal item, separator,
or submenu.

If an item is one of the non-normal classes (submenu, separator), only the
label of the item needs to be respected. Otherwise, all the properties
of the item contribute to the item's appearance and state.

Implementing the appearance of the menu item is up to toolkits, and certain
toolkits may choose to ignore certain properties, like icon or accel. The
role of the item determines its accessibility role, along with its
decoration if the GtkMenuTrackerItem::toggled property is true. As an
example, if the item has the role %GTK_MENU_TRACKER_ITEM_ROLE_CHECK and
GtkMenuTrackerItem::toggled is %FALSE, its accessible role should be that of
a check menu item, and no decoration should be drawn. But if
GtkMenuTrackerItem::toggled is %TRUE, a checkmark should be drawn.

All properties except for the two class-determining properties,
GtkMenuTrackerItem::is-separator and GtkMenuTrackerItem::has-submenu are
allowed to change, so listen to the notify signals to update your item's
appearance. When using a GObject library, this can conveniently be done
with g_object_bind_property() and #GBinding, and this is how this is
implemented in GTK+; the appearance side is implemented in #GtkModelMenuItem.

When an item is clicked, simply call gtk_menu_tracker_item_activated() in
response. The #GtkMenuTrackerItem will take care of everything related to
activating the item and will itself update the state of all items in
response.

Submenus are a special case of menu item. When an item is a submenu, you
should create a submenu for it with gtk_menu_tracker_new_item_for_submenu(),
and apply the same menu tracking logic you would for a toplevel menu.
Applications using submenus may want to lazily build their submenus in
response to the user clicking on it, as building a submenu may be expensive.

Thus, the submenu has two special controls -- the submenu's visibility
should be controlled by the GtkMenuTrackerItem::submenu-shown property,
and if a user clicks on the submenu, do not immediately show the menu,
but call gtk_menu_tracker_item_request_submenu_shown() and wait for the
GtkMenuTrackerItem::submenu-shown property to update. If the user navigates,
the application may want to be notified so it can cancel the expensive
operation that it was using to build the submenu. Thus,
gtk_menu_tracker_item_request_submenu_shown() takes a boolean parameter.
Use %TRUE when the user wants to open the submenu, and %FALSE when the
user wants to close the submenu.</doc>
