[PATCH] tablet-shell: come back to life
Tiago Vignatti
tiago.vignatti at intel.com
Tue Mar 27 14:10:47 PDT 2012
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. The icons seen on the homescreen are still
quite tiny.
