Drag and Drop is a direct manipulation gesture found in many Graphical User
Interface systems that provides a mechanism to transfer information between
two entities logically associated with presentation elements in the GUI.
The SystemFlavorMap is a configurable map between "natives" (Strings), which
correspond to platform-specific data formats, and "flavors" (DataFlavors),
which correspond to platform-independent MIME types.
Start a drag, given the DragGestureEvent
that initiated the drag, the initial
Cursor to use,
the Image to drag,
the offset of the Image origin
from the hotspot of the Cursor at
the instant of the trigger,
the Transferable subject data
of the drag, the DragSourceListener,
and the FlavorMap.
Creates a new DropTarget given the Component
to associate itself with, an int representing
the default acceptable action(s) to
support, a DropTargetListener
to handle event processing, a boolean indicating
if the DropTarget is currently accepting drops, and
a FlavorMap to use (or null for the default FlavorMap).
