From ba974a4e9f17e5f75efebe312e8bd1b24ad7b06d Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Tue, 30 Nov 2021 20:55:04 +0100 Subject: scene: add wlr_scene_get_scene_output This allows getting a wlr_scene_output from a wlr_output. Since an output can only be added once to a scene-graph there's no ambiguity. This is useful for compositors using wlr_scene_attach_output_layout: the output layout integration automatically creates a scene-graph output for each wlr_output added to the layout. --- include/wlr/types/wlr_scene.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'include/wlr') diff --git a/include/wlr/types/wlr_scene.h b/include/wlr/types/wlr_scene.h index 622dbb28..bca0b269 100644 --- a/include/wlr/types/wlr_scene.h +++ b/include/wlr/types/wlr_scene.h @@ -282,6 +282,13 @@ bool wlr_scene_output_commit(struct wlr_scene_output *scene_output); */ void wlr_scene_output_for_each_surface(struct wlr_scene_output *scene_output, wlr_surface_iterator_func_t iterator, void *user_data); +/** + * Get a scene-graph output from a wlr_output. + * + * If the output hasn't been added to the scene-graph, returns NULL. + */ +struct wlr_scene_output *wlr_scene_get_scene_output(struct wlr_scene *scene, + struct wlr_output *output); /** * Attach an output layout to a scene. -- cgit v1.2.3
