NAME
XmTrackingEvent — A Toolkit function that provides a modal interaction
SYNOPSIS
#include <Xm/Xm.h>
Widget XmTrackingEvent(
Widget widget,
Cursor cursor,
Boolean confine_to,
XEvent *event_return);
DESCRIPTION
XmTrackingEvent provides a modal interface for selection of a
component. It is intended to support context help. The function calls
the XmUpdateDisplay function. XmTrackingEvent then grabs the pointer
and discards succeeding events until BSelect is released or a key is
pressed and then released. The function then returns the widget or
gadget that contains the pointer when BSelect is released or a key is
released, and ungrabs the pointer.
widget Specifies the widget ID of a widget to use as the basis of
the modal interaction. That is, the widget within which the
interaction must occur, usually a top-level shell.
cursor Specifies the cursor to be used for the pointer during the
interaction. This is a standard X cursor name.
confine_to
Specifies whether or not the cursor should be confined to
widget.
event_return
Returns the ButtonRelease or KeyRelease event that causes the
function to return.
RETURN
Returns the widget or gadget that contains the pointer when BSelect is
released or a key is released. If no widget or gadget contains the
pointer, the function returns NULL.
