up-down-control

Arguments: widget

Returns the up-down-control control associated with the control specific by the argument widget, if there is one. Returns nil if there is no associated up-down control. Up-down controls are usually associated with editable-text controls but the argument can be any type of control.

If an up-down control (rather than nil) is returned, applying buddy-widget to that up-down control should return widget.
