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  interac-
		 tion.	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.
