XmDropSiteRegister - Man Page

#include <Xm/DragDrop​.h>
void XmDropSiteRegister(
Widget widget,
ArgList arglist,
Cardinal argcount);

XmDropSiteRegister identifies the specified widget or gadget as a drop site and sets resource values that define the drop site​'s behavior​. The routine assigns default values to any resources that are not specified in the argument list​. The toolkit generates a warning message if a drop site is registered with XmNdropSiteActivity set to XmDROP_SITE_ACTIVE and the XmNdropProc resource is NULL​.

If the drop site is a descendant of a widget that is registered as a drop site, the XmNdropSiteType resource of the ancestor drop site must be specified as XmDROP_SITE_COMPOSITE​. The ancestor must be registered before the descendant​. The drop site is stacked above all other sibling drop sites already registered​.
