-/* The org.gtk.Actions interface
- * =============================
- *
- * This interface describes a group of actions.
- *
- * Each action:
- * - has a unique string name
- * - can be activated
- * - optionally has a parameter type that must be given to the activation
- * - has an enabled state that may be true or false
- * - optionally has a state which can change value, but not type
- *
- * Methods
- * -------
- *
- * List :: () → (as)
- *
- *   Lists the names of the actions exported at this object path.
- *
- * Describe :: (s) → (bgav)
- *
- *   Describes a single action, or a given name.
- *
- *   The return value has the following components:
- *   b: specifies if the action is currently enabled. This is
- *      a hint that attempting to interact with the action will
- *      produce no effect.
- *   g: specifies the optional parameter type. If not "",
- *      the string specifies the type of argument that must
- *      be passed to the activation.
- *   av: specifies the optional state. If not empty, the array
- *       contains the current value of the state as a variant
- *
- * DescribeAll :: () → (a{s(bgav)})
- *
- *   Describes all actions in a single round-trip.
- *
- *   The dictionary maps action name strings to their descriptions
- *   (in the format discussed above).
- *
- * Activate :: (sava{sv}) → ()
- *
- *   Requests activation of the named action.
- *
- *   The action is named by the first parameter (s).
- *
- *   If the action activation requires a parameter then this parameter
- *   must be given in the second parameter (av). If there is no parameter
- *   to be specified, the array must be empty.
- *
- *   The final parameter (a{sv}) is a list of "platform data".
- *
- *   This method is not guaranteed to have any particular effect. The
- *   implementation may take some action (including changing the state
- *   of the action, if it is stateful) or it may take none at all. In
- *   particular, callers should expect their request to be completely
- *   ignored when the enabled flag is false (but even this is not
- *   guaranteed).
- *
- * SetState :: (sva{sv}) → ()
- *
- *   Requests the state of an action to be changed to the given value.
- *
- *   The action is named by the first parameter (s).
- *
- *   The requested new state is given in the second parameter (v).
- *   It must be equal in type to the existing state.
- *
- *   The final parameter (a{sv}) is a list of "platform data".
- *
- *   This method is not guaranteed to have any particular effect.
- *   The implementation of an action can choose to ignore the requested
- *   state change, or choose to change its state to something else or
- *   to trigger other side effects. In particular, callers should expect
- *   their request to be completely ignored when the enabled flag is
- *   false (but even this is not guaranteed).
- *
- * Signals
- * -------
- *
- * Changed :: (asa{sb}a{sv}a{s(bgav)})
- *
- *   Signals that some change has occured to the action group.
- *
- *   Four separate types of changes are possible, and the 4 parameters
- *   of the change signal reflect these possibilities:
- *   as: a list of removed actions
- *   a{sb}: a list of actions that had their enabled flag changed
- *   a{sv}: a list of actions that had their state changed
- *   a{s(bgav)}: a list of new actions added in the same format as
- *               the return value of the DescribeAll method

-/* The org.gtk.Menus interface
+/* For documentation of this interface, see
- * ===========================
+ * http://live.gnome.org/GTK+/GApplication-dbus-apis
- *
- * The interface is primarily concerned with three things:
- *
- * - communicating menus to the client
- * - establishing links between menus and other menus
- * - notifying clients of changes
- *
- * As a basic principle, it is recognised that the menu structure
- * of an application is often large. It is also recognised that some
- * menus are liable to frequently change without the user ever having
- * opened the menu. For both of these reasons, the individual menus are
- * arranged into subscription groups. Each subscription group is specified
- * by an unsigned integer. The assignment of integers need not be consecutive.
- *
- * Within a subscription group there are multiple menus. Each menu is
- * identified with an unsigned integer, unique to its subscription group.
- *
- * By convention, the primary menu is numbered 0 without subscription group 0.
- *
- * Actionable menu items (ie: those that produce some effect in the
- * application when they are activated) have a related action, specified by
- * a string. This string specifies the name of the action, according to the
- * org.gtk.Actions interface, at the same object path as the menu.
- *
- * Methods
- * -------
- *
- * Start :: (au) → (a(uuaa{sv}))
- *
- *   The Start method is used to indicate that a client is interested in
- *   tracking and displaying the content of the menus of a particular list
- *   of subscription groups.
- *
- *   Most typically, the client will request subscription group 0 to start.
- *
- *   The call has two effects. First, it replies with all menus defined
- *   within the requested subscription groups. The format of the reply is
- *   an array of tuples, where the items in each tuple are:
- *   - the subscription group of the menu
- *   - the number of the menu within that group
- *   - an array of menu items
- *
- *   Each menu item is a dictionary of attributes (a{sv}).
- *
- *   Secondly, this call has a side effect: it atomically requests that
- *   the Changed signal start to be emitted for the requested subscription
- *   group. Each group has a subscription count and only signals changes
- *   on itself when this count is greater than zero.
- *
- *   If a group is specified multiple times then the result is that the
- *   contents of that group is only returned once, but the subscription
- *   count is increased multiple times.
- *
- *   If a client disconnects from the bus while holding subscriptions then
- *   its subscriptions will be cancelled. This prevents "leaking" subscriptions
- *   in the case of crashes and is also useful for applications that want
- *   to exit without manually cleaning up.
- *
- * End :: (au)
- *
- *   The End method reverses the previous effects of a call to Start.
- *
- *   When clients are no longer interested in the contents of a subscription
- *   group, they should call the End method.
- *
- *   The parameter lists the subscription groups. A subscription group
- *   needs to be cancelled the same number of times as it was requested.
- *   For this reason, it might make sense to specify the same subscription
- *   group multiple times (if multiple Start calls were made for this group).
- *
- * Signals
- * -------
- *
- * Changed :: (a(uuuuaa{sv}))
- *
- *   The changed signal indicates changes to a particular menu.
- *
- *   The changes come as an array of tuples where the items in each tuple are:
- *   - the subscription group of the menu
- *   - the number of the menu within that group
- *   - the position in the menu at which to make the change
- *   - the number of items to delete from that position
- *   - a list of new items to insert at that position
- *
- *   Each new menu item is a dictionary of attributes (a{sv}).
- *
- * Attributes
- * ----------
- *
- * label (string): the label to display
- * action (string): the name of the action
- * target (variant): the parameter to pass when activating the action
- * :section ((uu)): the menu to use to populate that section, specified
- *     as a pair of subscription group and menu within that group
- * :submenu ((uu)): the menu to use as a submenu, specified
- *     as a pair of subscription group and menu within that group
