Detailed Description

The drag source context class is responsible for managing the initiator side of the Drag and Drop protocol.

In particular, it is responsible for managing event notifications to the DragSourceListener and providing the Transferable state to enable the data transfer.

An instance of this class is created as a result of the method XDragSource::startDrag() being successfully invoked. This instance is responsible for tracking the state of the operation on behalf of the drag source and dispatching state changes to the drag source listener.
