--- Comment #3 from Jasper St. Pierre <jstpierre at mecheye.net> 2014-05-02 16:15:07 UTC ---
I don't like this API here. Really, subsurfaces match child windows, so I'd
like to see this match gdk_window_move. get_wl_subsurface should retrieve the
wl_subsurface; we already have a gdk_wayland_window_get_wl_surface API that we
can use.

We also need to look at making it work with pointer focus. The compositor will
send a leave/enter pair when the pointer enters a subsurface, so we need to
make sure that the surface is properly tracked with the toplevel. That means
that the user_data is set properly, so we should reuse the existing code that
creates the wl_surface.
