- * clutter_threads_add_idle: (skip)
- * @func: function to call

- *
- * Adds a function to be called whenever there are no higher priority
- * events pending. If the function returns %FALSE it is automatically
- * removed from the list of event sources and will not be called again.
- *
- * This function can be considered a thread-safe variant of g_idle_add_full():
- * it will call @function while holding the Clutter lock. It is logically
- * equivalent to the following implementation:
- *
- * ```c
- * static gboolean
- * idle_safe_callback (gpointer data)
- * {
- *    SafeClosure *closure = data;
- *    gboolean res = FALSE;
- *
- *    // the callback does not need to acquire the Clutter
- *     / lock itself, as it is held by the this proxy handler
- *     //
- *    res = closure->callback (closure->data);
- *
- *    return res;
- * }
- * static gulong
- * add_safe_idle (GSourceFunc callback,
- *                gpointer    data)
- * {
- *   SafeClosure *closure = g_new0 (SafeClosure, 1);
- *
- *   closure->callback = callback;
- *   closure->data = data;
- *
- *   return g_idle_add_full (G_PRIORITY_DEFAULT_IDLE,
- *                           idle_safe_callback,
- *                           closure,
- *                           g_free)
- * }
- * ```
- *
- * This function should be used by threaded applications to make sure
- * that @func is emitted under the Clutter threads lock and invoked
- * from the same thread that started the Clutter main loop. For instance,
- * it can be used to update the UI using the results from a worker
- * thread:
- *
- * ```c
- * static gboolean
- * update_ui (gpointer data)
- * {
- *   SomeClosure *closure = data;
- *
- *   // it is safe to call Clutter API from this function because
- *    / it is invoked from the same thread that started the main
- *    / loop and under the Clutter thread lock
- *    //
- *   clutter_label_set_text (CLUTTER_LABEL (closure->label),
- *                           closure->text);
- *
- *   g_object_unref (closure->label);
- *   g_free (closure);
- *
- *   return FALSE;
- * }
- *
- *   // within another thread //
- *   closure = g_new0 (SomeClosure, 1);
- *   // always take a reference on GObject instances //
- *   closure->label = g_object_ref (my_application->label);
- *   closure->text = g_strdup (processed_text_to_update_the_label);
- *
- *   clutter_threads_add_idle (update_ui,
- *                             closure);
- * ```
- *
- * Return value: the ID (greater than 0) of the event source.
