XFilterEvent(XS)  X Version 11 (Release 5) 6 January 1993   XFilterEvent(XS)


 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 pro-
    vided 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.
