Description

XmTrackingLocate provides a modal interface for selection of a component. It is intended to support context help. The function 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.

This function is obsolete and exists for compatibility with previous releases. It has been replaced by XmTrackingEvent.

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.

Return values

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.
