From 0a38611e7deadc8c3dc4fc65111047c89e72ba8b Mon Sep 17 00:00:00 2001 From: Tiago Vignatti Date: Wed, 28 Mar 2012 13:04:02 +0300 Subject: tablet-shell: come back to life A couple of fixes were made: Weston tablet-shell needed to use weston_layer, so the compositor could rebuild the surface list correctly when repainting; homescreen and locking are using the widget + window abstration of toytoolkit; and widget_set_redraw_handler are being set for widgets redraw. Also, it was given some basic meaning for lockscreen_button_handler, which was completely disabled before. As a clean up, I updated the global listener mechanism on tablet-shell client, using the regular way of registering a handler instead wl_display_roundtrip -> wl_display_get_global. Switcher still without code to proper work and the same for tablet-shell clients, which are not launched. krh: Edited to not scale down homescreen icons, use new load_cairo_surface() for image loading.
