CVS2003-05-29 Rob Adams <robadams@ucla.edu> Use a new property _METACITY_SENTINEL to eliminate a race condition that causes focus to behave badly with sloppy/mouse focus when lots of windows are mapped/unmapped, such as with a workspace switch. The EnterNotify events on a display are ignored until the PropertyNotify sent after all the window maps is received. This is a fix for #110970. * src/display.[ch]: New _METACITY_SENTINEL atom. (event_callback): ignore EnterNotify if the sentinel isn't clear, and decrement the sentinel counter when the PropertyNotify is received. (meta_display_increment_focus_sentinel): new function. Increments the sentinel counter and updates the property on a root window on this display. (meta_display_decrement_focus_sentinel): Decrement the sentinel counter. (meta_display_focus_sentinel_clear): returns whether the sentinel counter is zero. * src/window.c (idle_calc_showing): after showing windows, call meta_display_increment_focus_sentinel on each display for windows to be shown. * src/workspace.[ch] (meta_workspace_activate_with_focus): new function activates a workspace and focuses a particular window after the workspace is activated. (meta_workspace_activate): now just a wrapper for meta_workspace_activate_with_focus * src/keybindings.c: use new meta_workspace_activate_with_focus function to ensure that focus will follow the focused window through the workspace switch. : ----------------------------------------------------------------------
