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.
