Can unmanged widgets be valid (drag-and-drop) drop sites?
[Last modified: Nov 96] Answer: Yes, the drop site stacking order is independent of the window stacking order. You can modify the active drop site order with XmDropSiteConfigureStackingOrder() or by using XmDropSiteUpdate() to change the drop site’s XmNdropSiteActivity resource (to XmDROP_SITE_ACTIVE or XmDROP_SITE_INACTIVE).
