DESCRIPTION [Toc] [Back]
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 [Toc] [Back]
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.
