From e9b9784c5c0e8aca37d89aca4588dbf945fed428 Mon Sep 17 00:00:00 2001 From: Georges Basile Stavracas Neto Date: Sun, 5 Jul 2020 17:57:37 -0300 Subject: [PATCH] clutter/offscreen-effect: Implement paint_node() The paint node tree that ClutterOffscreenEffect generates is simple: Root |------------+ | | Layer Pipeline | Actor Right now, both pre-paint and ClutterLayerNode push the offscreen to the framebuffer stack. That's harmless, and will go away soon anyway. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1355 --- clutter/clutter/clutter-offscreen-effect.c | 25 ++++++++++++++++++++++ 1 file changed, 25 insertions(+) diff --git a/clutter/clutter/clutter-offscreen-effect.c b/clutter/clutter/clutter-offscreen-effect.c index f583c5aaa..01930f0f5 100644 --- a/clutter/clutter/clutter-offscreen-effect.c +++ b/clutter/clutter/clutter-offscreen-effect.c @@ -483,6 +483,30 @@ clutter_offscreen_effect_post_paint (ClutterEffect *effect, clutter_offscreen_effect_paint_texture (self, paint_context); } +static void +clutter_offscreen_effect_paint_node (ClutterEffect *effect, + ClutterPaintNode *node, + ClutterPaintContext *paint_context, + ClutterEffectPaintFlags flags) +{ + ClutterOffscreenEffect *offscreen_effect = CLUTTER_OFFSCREEN_EFFECT (effect); + ClutterOffscreenEffectPrivate *priv = offscreen_effect->priv; + ClutterPaintNode *layer_node; + ClutterPaintNode *actor_node; + + layer_node = clutter_layer_node_new_with_framebuffer (priv->offscreen, + priv->pipeline, + 255); + clutter_paint_node_set_static_name (layer_node, + "ClutterOffscreenEffect (actor offscreen)"); + clutter_paint_node_add_child (node, layer_node); + clutter_paint_node_unref (layer_node); + + actor_node = clutter_actor_node_new (priv->actor, 255); + clutter_paint_node_add_child (layer_node, actor_node); + clutter_paint_node_unref (actor_node); +} + static void clutter_offscreen_effect_paint (ClutterEffect *effect, ClutterPaintContext *paint_context, @@ -556,6 +580,7 @@ clutter_offscreen_effect_class_init (ClutterOffscreenEffectClass *klass) effect_class->pre_paint = clutter_offscreen_effect_pre_paint; effect_class->post_paint = clutter_offscreen_effect_post_paint; effect_class->paint = clutter_offscreen_effect_paint; + effect_class->paint_node = clutter_offscreen_effect_paint_node; gobject_class->finalize = clutter_offscreen_effect_finalize; }
