XFilterEvent(3X11)

NAME
       XFilterEvent - filter X events for an input method

SYNTAX
       Bool XFilterEvent(event, w)
             XEvent *event;
             Window w;

ARGUMENTS
       event     Specifies the event to filter.

       w         Specifies the window for which the filter is to
                 be applied.

DESCRIPTION
       If the window argument is None, XFilterEvent applies the
       filter to the window specified in the XEvent structure.
       The window argument is provided so that layers above Xlib
       that do event redirection can indicate to which window an
       event has been redirected.

       If XFilterEvent returns True, then some input method has
       filtered the event, and the client should discard the
       event.  If XFilterEvent returns False, then the client
       should continue processing the event.

       If a grab has occurred in the client and XFilterEvent
       returns True, the client should ungrab the keyboard.
