[PATCH weston 10/14] notify_key: Add update_state argument

Daniel Stone daniel at fooishbar.org
Fri Jun 22 05:21:37 PDT 2012


If update_state is true, then notify_key will continue to call
xkb_key_update_state to update the local state mask, as before this
commit.  Otherwise, it will rely on the compositor to manually update
the state itself, for nested compositors.
