NAME
XFilterEvent - filter X events for an input method
SYNOPSIS
Bool XFilterEvent(event, w)
XEvent *event;
Window w;
ARGUMENTS
Specifies the event to filter. Specifies the window for which the fil-
ter 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.
