It is important -that all unused fields of the structure be set to zero. -.BE -.SH DESCRIPTION -.PP -\fBTk_HandleEvent\fR is a lower-level procedure that deals with window -events. It is called by \fBTcl_ServiceEvent\fR (and indirectly by -\fBTk_DoOneEvent\fR), and in a few other cases within Tk. -It makes callbacks to any window event -handlers (created by calls to \fBTk_CreateEventHandler\fR) -that match \fIeventPtr\fR and then returns. In some cases -it may be useful for an application to bypass the Tk event -queue and call \fBTk_HandleEvent\fR directly instead of -calling \fBTcl_QueueEvent\fR followed by -\fBTcl_ServiceEvent\fR. -.PP -This procedure may be invoked recursively. For example, -it is possible to invoke \fBTk_HandleEvent\fR recursively -from a handler called by \fBTk_HandleEvent\fR. This sort -of operation is useful in some modal situations, such -as when a -notifier has been popped up and an application wishes to -wait for the user to click a button in the notifier before -doing anything else. -.SH KEYWORDS -callback, event, handler, window |
