2008-05-12 Emmanuele Bassi <ebassi@openedhand.com> Rework the stage wrapper/implementation relation: remove duplicated code and all the bookkeeping from the backends into ClutterStage whenever possible, to reduce the amount of work a backend must do (and possibly get wrong). Thanks to Tommi Komulainen. * clutter/clutter-main.c: (clutter_init_with_args), (clutter_init): Realize the default stage after creation. The default stage is special, because we use it in the initialization sequence. This removes the burden from the backends and reduces the things a backend can get wrong. * clutter/clutter-stage.c: (clutter_stage_show): Make sure to realize the implementation if it hasn't been realized yet. (clutter_stage_realize): Set the REALIZED flag and call clutter_stage_ensure_current() if the implementation was successfully realized. (clutter_stage_unrealized): Call clutter_stage_ensure_current() on unrealize. * clutter/glx/clutter-backend-glx.c: (clutter_backend_glx_create_stage): Do not realize the stage anymore when creating it, and let the normal realization sequence take place. (clutter_backend_glx_ensure_context): Trap for X11 errors. * clutter/glx/clutter-stage-glx.c: (clutter_stage_glx_realize): Chain up to the X11 implementation so that we can set up the window state (title, cursor visibility) when we actually have a X window. Also, do not call clutter_stage_ensure_current(), and rely on the wrapper to do it for us. This means we can drop setting the REALIZED flag on the wrapper. (clutter_stage_glx_unrealize): Do not call clutter_stage_ensure_current() ourselves, and rely on the wrapper to do it for us. * clutter/x11/clutter-stage-x11.c: (set_wm_title), (set_cursor_visible): Move the WM title and cursor visibility code inside their own functions. (clutter_stage_x11_realize): Set the window title and whether the cursor is visible or not after realizing the stage.
