-.SH NAME
-Tk_HandleEvent \- invoke event handlers for window system events
-.SH SYNOPSIS
-.nf
-\fB#include <tk.h>\fR
-.sp
-\fBTk_HandleEvent\fR(\fIeventPtr\fR)
-.SH ARGUMENTS

-.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
