From ffaec917e507a8bb500d6fc4fd2e9d9e1856e6f1 Mon Sep 17 00:00:00 2001 From: Carlos Garnacho Date: Fri, 10 Aug 2018 21:33:50 +0200 Subject: [PATCH] clutter: Only redraw affected portions on parent widget on show/hide If we are lucky enough and the parent actor has the CLUTTER_ACTOR_NO_LAYOUT flag, we would skip the relayout, but still redraw the parent actor in its entirety. In these cases, we can at least just redraw the area affected by the actor being shown/hidden. --- clutter/clutter/clutter-actor.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/clutter/clutter/clutter-actor.c b/clutter/clutter/clutter-actor.c index 6913f315a..521d4264c 100644 --- a/clutter/clutter/clutter-actor.c +++ b/clutter/clutter/clutter-actor.c @@ -1793,7 +1793,7 @@ clutter_actor_show (ClutterActor *self) g_object_notify_by_pspec (G_OBJECT (self), obj_props[PROP_VISIBLE]); if (priv->parent != NULL) - clutter_actor_queue_redraw (priv->parent); + clutter_actor_queue_redraw (self); g_object_thaw_notify (G_OBJECT (self)); } @@ -1918,8 +1918,10 @@ clutter_actor_hide (ClutterActor *self) g_signal_emit (self, actor_signals[HIDE], 0); g_object_notify_by_pspec (G_OBJECT (self), obj_props[PROP_VISIBLE]); - if (priv->parent != NULL) + if (priv->parent != NULL && priv->needs_allocation) clutter_actor_queue_redraw (priv->parent); + else + clutter_actor_queue_redraw_on_parent (self); g_object_thaw_notify (G_OBJECT (self)); }
