Required Methods§

source

fn next(&self) -> Option<(GString, MenuModel)>

This function combines g_menu_link_iter_next() with g_menu_link_iter_get_name() and g_menu_link_iter_get_value().

First the iterator is advanced to the next (possibly first) link. If that fails, then false is returned and there are no other effects.

If successful, out_link and value are set to the name and MenuModel of the link that has just been advanced to. At this point, g_menu_link_iter_get_name() and g_menu_link_iter_get_value() will return the same values again.

The value returned in out_link remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using g_object_unref() when it is no longer in use.

Returns

true on success, or false if there is no additional link

the name of the link

value

the linked MenuModel
