From: Ander Conselvan de Oliveira Date: Thu, 21 Feb 2013 16:35:20 +0000 (+0200) Subject: compositor: Move fade animation out of core Weston into shell X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19d10ef925494dac7da1806c03d6f59584bc0517;p=profile%2Fivi%2Fweston-ivi-shell.git compositor: Move fade animation out of core Weston into shell Previously, it was impossible to override the fade in/out behavior of Weston using a different shell, since this was implemented in core Weston. This also led to complicated interaction between the shell and the core when displaying lock surfaces and screensavers. This patch starts to solve this issue by moving the fade animation out of the core. On compositor.c, besides deleting the fade code, the idle handler had to be changed to emit the lock signal, since it was called from the fade_frame() function before. This causes a slight change of behavior, since before the fade would happen with the compositor being active, while now it is already in the idle state. That leads to the dpms state being set when cancelling the fade with mouse movement, and in turn, to a slight freeze with drm compositor. This problem will be fixed in a follow up patch. On the shell side, the fade was re-implemented in a slightly different manner. Instead of using a custom frame function, the fade animation from animation.c is used. The interface for starting the fade was also changed to take the value of an enum instead of a float alpha value, in order to improve readability. --- diff --git a/src/compositor.c b/src/compositor.c index 9872bfe..dab9db7 100644 --- a/src/compositor.c +++ b/src/compositor.c @@ -1053,40 +1053,6 @@ weston_output_damage(struct weston_output *output) } static void -fade_frame(struct weston_animation *animation, - struct weston_output *output, uint32_t msecs) -{ - struct weston_compositor *compositor = - container_of(animation, - struct weston_compositor, fade.animation);
