From e937f1f5a385b44f37d943c34cdc06871483714e Mon Sep 17 00:00:00 2001 From: Rafael Antognolli Date: Thu, 18 Apr 2013 16:10:53 -0300 Subject: [PATCH] evas/wayland: Unclip objects from the framespace after rendering. These objects should be clipped only during rendering, since keeping them clipped after that allows for unexpected behavior on the application side. For instance, an application could check if objects have clippers before doing something to them, assuming that some objects should have no clipper, but under wayland, after the first render iteration, there will be no objects without a clipper. This commit fixes this behavior by unclipping objects that had no clipper prior to the render iteration. Additionally, it fixes a bug where a maximized/fullscreen window could have not all of its content rendered immediately. This was occuring because some objects could be clipped to the framespace clipper, but considered invisible in the beginning of the render phase, where they are evaluated. They were considered invisible because the framespace clipper object was not resized at that phase yet, and thus these objects were being clipped out from the viewport. --- src/lib/evas/canvas/evas_main.c | 2 + src/lib/evas/canvas/evas_render.c | 176 ++++++++++++++++------------ src/lib/evas/include/evas_private.h | 1 + 3 files changed, 103 insertions(+), 76 deletions(-) diff --git a/src/lib/evas/canvas/evas_main.c b/src/lib/evas/canvas/evas_main.c index beebbb3926..79babed6f0 100644 --- a/src/lib/evas/canvas/evas_main.c +++ b/src/lib/evas/canvas/evas_main.c @@ -164,6 +164,7 @@ _constructor(Eo *eo_obj, void *class_data, va_list *list EINA_UNUSED) EVAS_ARRAY_SET(e, obscuring_objects); EVAS_ARRAY_SET(e, temporary_objects); EVAS_ARRAY_SET(e, calculate_objects); + EVAS_ARRAY_SET(e, clipped_objects); EVAS_ARRAY_SET(e, clip_changes); EVAS_ARRAY_SET(e, scie_unref_queue); EVAS_ARRAY_SET(e, image_unref_queue); @@ -276,6 +277,7 @@ _destructor(Eo *eo_e, void *_pd, va_list *list EINA_UNUSED) eina_array_flush(&e->obscuring_objects); eina_array_flush(&e->temporary_objects); eina_array_flush(&e->calculate_objects); + eina_array_flush(&e->clipped_objects); eina_array_flush(&e->clip_changes); eina_array_flush(&e->scie_unref_queue); eina_array_flush(&e->image_unref_queue); diff --git a/src/lib/evas/canvas/evas_render.c b/src/lib/evas/canvas/evas_render.c index ecdad310b2..23c081da28 100644 --- a/src/lib/evas/canvas/evas_render.c +++ b/src/lib/evas/canvas/evas_render.c @@ -1431,6 +1431,103 @@ _drop_image_cache_ref(const void *container EINA_UNUSED, void *data, void *fdata return EINA_TRUE; } +static void +_framespace_clipper_add(Evas *eo_e, Evas_Public_Data *e) +{ + Eina_Rectangle clip_rect; + unsigned int i; + Evas_Object *eo_obj; + Evas_Object_Protected_Data *obj; + + if (strncmp(e->engine.module->definition->name, "wayland", 7)) + return; + + /* see if the master clip has been added yet, if not, then create */ + if (!e->framespace.clip) + { + e->framespace.clip = evas_object_rectangle_add(eo_e); + evas_object_color_set(e->framespace.clip, 255, 255, 255, 255); + evas_object_move(e->framespace.clip, + e->framespace.x, e->framespace.y); + evas_object_resize(e->framespace.clip, + e->viewport.w - e->framespace.w, + e->viewport.h - e->framespace.h); + } + else + { + /* master clip is already present. check for size changes in the + * viewport, and update master clip size if needed */ + if ((e->viewport.changed) || (e->output.changed) || + (e->framespace.changed)) + { + evas_object_move(e->framespace.clip, + e->framespace.x, e->framespace.y); + evas_object_resize(e->framespace.clip, + e->viewport.w - e->framespace.w, + e->viewport.h - e->framespace.h); + } + } + + Evas_Object_Protected_Data *framespace_clip = + eo_data_get(e->framespace.clip, EVAS_OBJ_CLASS); + + EINA_RECTANGLE_SET(&clip_rect, + framespace_clip->cur->geometry.x, + framespace_clip->cur->geometry.y, + framespace_clip->cur->geometry.w, + framespace_clip->cur->geometry.h); + + evas_object_show(e->framespace.clip); + /* With the master clip all setup, we need to loop the objects on this + * canvas and determine if the object is in the viewport space.
