public class DragSourceDragEvent extends DragSourceEvent
DragSourceDragEvent is
 delivered from the DragSourceContextPeer,
 via the DragSourceContext, to the DragSourceListener
 registered with that DragSourceContext and with its associated
 DragSource.
 
 The DragSourceDragEvent reports the target drop action
 and the user drop action that reflect the current state of
 the drag operation.
 
 Target drop action is one of DnDConstants that represents
 the drop action selected by the current drop target if this drop action is
 supported by the drag source or DnDConstants.ACTION_NONE if this
 drop action is not supported by the drag source.
 
User drop action depends on the drop actions supported by the drag source and the drop action selected by the user. The user can select a drop action by pressing modifier keys during the drag operation:
Ctrl + Shift -> ACTION_LINK Ctrl -> ACTION_COPY Shift -> ACTION_MOVEIf the user selects a drop action, the user drop action is one of
DnDConstants that represents the selected drop action if this
 drop action is supported by the drag source or
 DnDConstants.ACTION_NONE if this drop action is not supported
 by the drag source.
 
 If the user doesn't select a drop action, the set of
 DnDConstants that represents the set of drop actions supported
 by the drag source is searched for DnDConstants.ACTION_MOVE,
 then for DnDConstants.ACTION_COPY, then for
 DnDConstants.ACTION_LINK and the user drop action is the
 first constant found. If no constant is found the user drop action
 is DnDConstants.ACTION_NONE.

DragSourceDragEvent.
 This class is typically
 instantiated by the DragSourceContextPeer
 rather than directly
 by client code.
 The coordinates for this DragSourceDragEvent
 are not specified, so getLocation will return
 null for this event.
 
 The arguments dropAction and action should
 be one of DnDConstants that represents a single action.
 The argument modifiers should be either a bitwise mask
 of old java.awt.event.InputEvent.*_MASK constants or a
 bitwise mask of extended java.awt.event.InputEvent.*_DOWN_MASK
 constants.
 This constructor does not throw any exception for invalid dropAction,
 action and modifiers.

            notifications for this event.dropAction - the user drop action.action - the target drop action.modifiers - the modifier keys down during event (shift, ctrl,

        Either extended _DOWN_MASK or old _MASK modifiers

        in one event. Use of the extended modifiers is
        preferred.IllegalArgumentException - if dsc is null.InputEvent,

public int getGestureModifiers()
int representing
 the current state of the input device modifiers
 associated with the user's gesture. Typically these
 would be mouse buttons or keyboard modifiers.
 
 If the modifiers passed to the constructor
 are invalid, this method returns them unchanged.
public int getGestureModifiersEx()
int representing
 the current state of the input device extended modifiers
 associated with the user's gesture.
 See InputEvent.getModifiersEx()
 
 If the modifiers passed to the constructor
 are invalid, this method returns them unchanged.
