A Drag and Drop function that retrieves the DragContext widget ID associated with a timestamp
Format
#include <Xm/DragC.h> Widget XmGetDragContext Widget refwidgetTime timestamp
DESCRIPTION
XmGetDragContext returns the widget ID of the active DragContext associated with a given display and timestamp. A timestamp uniquely identifies which DragContext is active when more than one drag and drop transaction has been initiated on a display. If the specified timestamp matches a timestamp processed between the start and finish of a single drag and drop transaction, the function returns the corresponding DragContext ID.
For a complete definition of DragContext and its associated resources, see XmDragContext (3).
RETURN
Returns the ID of the DragContext widget that is active for the specified timestamp. Otherwise, returns NULL if no active DragContext is found.
