.SH NAME
XFilterEvent \- filter X events for an input method
.SH SYNTAX
.HP
Bool XFilterEvent\^(\^XEvent *\fIevent\fP\^, Window \fIw\fP\^);
.SH ARGUMENTS
.ds Ev event to filter
.IP \fIevent\fP 1i
Specifies the \*(Ev.
.ds Wi for which the filter is to be applied
.IP \fIw\fP 1i
Specifies the window \*(Wi.
.SH DESCRIPTION
If the window argument is
.ZN None ,
.ZN XFilterEvent
applies the filter to the window specified in the
.ZN 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.
.LP
If
.ZN XFilterEvent
returns
.ZN True ,
then some input method has filtered the event,
and the client should discard the event.
If
.ZN XFilterEvent
returns
.ZN False ,
then the client should continue processing the event.
.LP
If a grab has occurred in the client and
.ZN XFilterEvent
returns
.ZN True ,
the client should ungrab the keyboard.
