                                                        (DbusmenuMenuitem *mi,

Look up a property on mi and return the value of it if it exits. NULL will be returned if the property doesn't exist.

dbusmenu_menuitem_property_exist ()

gboolean            dbusmenu_menuitem_property_exist    (DbusmenuMenuitem *mi,
                                                         const gchar *property);

Checkes to see if a particular property exists on mi and returns TRUE if so.

dbusmenu_menuitem_properties_list ()

GList *             dbusmenu_menuitem_properties_list   (DbusmenuMenuitem *mi);

This functiong gets a list of the names of all the properties that are set on this menu item. This data on the list is owned by the menuitem but the list is not and should be freed using g_list_free() when the calling function is done with it.

dbusmenu_menuitem_properties_copy ()

GHashTable *        dbusmenu_menuitem_properties_copy   (DbusmenuMenuitem *mi);

This function takes the properties of a DbusmenuMenuitem and puts them into a GHashTable that is referenced by the key of a string and has the value of a string. The hash table may not have any entries if there aren't any or there is an error in processing. It is the caller's responsibility to destroy the created GHashTable.

dbusmenu_menuitem_property_remove ()

void                dbusmenu_menuitem_property_remove   (DbusmenuMenuitem *mi,
                                                         const gchar *property);

Removes a property from the menuitem.

dbusmenu_menuitem_set_root ()

void                dbusmenu_menuitem_set_root          (DbusmenuMenuitem *mi,
                                                         gboolean root);

This function sets the internal value of whether this is a root node or not.

dbusmenu_menuitem_get_root ()

gboolean            dbusmenu_menuitem_get_root          (DbusmenuMenuitem *mi);

This function returns the internal value of whether this is a root node or not.

dbusmenu_menuitem_foreach ()

void                dbusmenu_menuitem_foreach           (DbusmenuMenuitem *mi,
                                                         void (*func) (DbusmenuMenuitem * mi, gpointer data),
                                                         gpointer data);

This calls the function func on this menu item and all of the children of this item. And their children. And their children. And... you get the point. It will get called on the whole tree.

dbusmenu_menuitem_handle_event ()

void                dbusmenu_menuitem_handle_event      (DbusmenuMenuitem *mi,
                                                         const gchar *name,
                                                         GVariant *variant,
                                                         guint timestamp);

This function is called to create an event. It is likely to be overrided by subclasses. The default menu item will respond to the activate signal and do:

Emits the "item-activate" signal on this menu item. Called by server objects when they get the appropriate DBus signals from the client.

If you subclass this function you should really think about calling the parent function unless you have a good reason not to.

dbusmenu_menuitem_send_about_to_show ()

void                dbusmenu_menuitem_send_about_to_show
                                                        (DbusmenuMenuitem *mi,
                                                         void (*cb) (DbusmenuMenuitem * mi, gpointer user_data),
                                                         gpointer cb_data);

This function is used to send the even that the submenu of this item is about to be shown. Callers to this event should delay showing the menu until their callback is called if possible.

dbusmenu_menuitem_show_to_user ()

void                dbusmenu_menuitem_show_to_user      (DbusmenuMenuitem *mi,
                                                         guint timestamp);

Signals that this menu item should be shown to the user. If this is server side the server will then take it and send it over the bus.

dbusmenu_menuitem_get_parent ()

DbusmenuMenuitem *  dbusmenu_menuitem_get_parent        (DbusmenuMenuitem *mi);

This function looks up the parent of mi

dbusmenu_menuitem_set_parent ()

gboolean            dbusmenu_menuitem_set_parent        (DbusmenuMenuitem *mi,
                                                         DbusmenuMenuitem *parent);

Sets the parent of mi to parent. If mi already has a parent, then this call will fail. The parent will be set automatically when using the usual methods to add a child menuitem, so this function should not normally be called directly

dbusmenu_menuitem_unparent ()

gboolean            dbusmenu_menuitem_unparent          (DbusmenuMenuitem *mi);

Unparents the menu item mi. If mi doesn't have a parent, then this call will fail. The menuitem will be unparented automatically when using the usual methods to delete a child menuitem, so this function should not normally be called directly
