o startDrag 
public void startDrag(Component c,
                      AWTEvent trigger,
                      int actions,
                      Cursor dragCursor,
                      Image dragImage,
                      Point imageOffset,
                      Transferable transferable,
                      DragSourceListener dsl) throws InvalidDnDOperationException, SecurityException
start a Drag operation.

Parameters:
c - The Component the Drag trigger occurred in
trigger - The AWTEvent that initiated the operation
actions - The drag "verbs" appropriate
dragCursor - The initial cursor or null for defaults
dragImage - The image to drag or null
imageOffset - The offset of the image origin from the hotspot of the cursor at the instant of the trigger
transferable - The subject data of the operation
dsl - The DragSourceListener Caller must have AWTPermission startDrag to succeed.
o createDragSourceContext 
protected DragSourceContext createDragSourceContext(DragSourceContextPeer dscp,
                                                    Component c,
                                                    int actions,
                                                    Cursor dragCursor,
                                                    Image dragImage,
                                                    Point imageOffset,
                                                    Transferable t,
                                                    DragSourceListener dsl)
Create the DragSourceContext to handle this Drag. To incorporate a new DragSourceContext subclass, subclass DragSource and override this method.

Parameters:
dscp - The DragSourceContextPeer for this operation
c - The Component the drag started in
actions - The drag "verbs" appropriate
dragCursor - The initial cursor
dragImage - The image to drag or null
imageOffset - The offset of the image origin from the hotspot of the cursor at the instant of the trigger
transferable - The subject data of the operation
dsl - The DragSourceListener
o getFlavorMap 
public FlavorMap getFlavorMap()
Returns:
the FlavorMap for this DragSource
