           Summary: Request for an extension to avoid RevertToNone
           Product: xorg
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: * Other
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: newren at gmail.com


I'm afraid I'm not sure of the appropriate component; my apologies.

This request stems from http://bugzilla.gnome.org/show_bug.cgi?id=125492.  If a
focus window becomes not viewable, then X states that the new focus window
depends on the revertto argument.  If revertto is Parent, the focus reverts to
the parent (or the closest viewable ancestor) and the new revertto value is
taken to be None.  However, if the Parent also becomes unviewable, then the
focus reverts to nothing which means that window manager keybindings break.

For now, we've added a hack to detect when no window becomes focused and
manually focus a window (our dummy "no_focus_window") so that keybindings don't
stop working.  As Havoc says in comment 9
(http://bugzilla.gnome.org/show_bug.cgi?id=125492#c9) of the gnome bug, "An X
extension to let us specify "revert to some specified window" (with side effect
that RevertToNone will never be used) would be welcome"
