XmGetDragContext — A Drag and Drop function that retrieves the
DragContext widget ID associated with a timestamp
#include <Xm/DragC.h>
Widget XmGetDragContext(
Widget refwidget,
Time timestamp);
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.
- refwidget
- Specifies the ID of the widget that the routine uses to identify the
intended display. The function returns the ID of the DragContext
associated with the display value passed by this widget.
- timestamp

For a complete definition of DragContext and its associated
resources, see XmDragContext(3).
Returns the ID of the DragContext widget that is active for the specified
timestamp. Otherwise, returns NULL if no active DragContext is found.
