I coincidentally just took a look at this for another reason, and this solution (not confirmed by me) for use with Motif 1.0 suggested itself: when the scrollbars are moved, the ScrolledWindow's internal callbacks are calling the internal function _XmMoveObject with the arguments of the workWindow widget, (vertical) the workWindow widget`s XmNx position, and the -offset of the amount to be moved; (horizontal) the -offset of the amount to be moved, and the workWindow widget`s XmNy position. The callbacks then set either the scrolledWindow's internal hOrigin or vOrigin value to that offset, in the appropriate case. It appears that you can reconstruct these two lines in application code and call them in addition to setting the scrollbar values. If you have source, check XmGadgetUtil.c. -- David B.
