If the procedure is already registered with +the same \fIclient_data\fP value, the specified mask augments the +existing mask and the procedure is repositioned in the list. +.LP +.ZN XtInsertRawEventHandler +is similar to +.ZN XtInsertEventHandler +except that it does not modify the widget's event mask and never causes an +.ZN XSelectInput +for the specified events. If the procedure is already registered with the +same \fIclient_data\fP value, the specified mask augments the existing +mask and the procedure is repositioned in the list. +.SH "SEE ALSO" +XtAppNextEvent(3Xt), +XtBuildEventMask(3Xt) +.br +\fI\*(xT\fP +.br +\fI\*(xL\fP |
