jdk.awt.dnd.DragSourceDragEvent
The 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_MOVE If 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.

(->drag-source-drag-event dsc drop-action action modifiers)(->drag-source-drag-event dsc drop-action action modifiers x y)Constructor.
Constructs a DragSourceDragEvent given the specified DragSourceContext, user drop action, target drop action, modifiers and coordinates.
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.

action - the target drop action. - int
modifiers - the modifier keys down during event (shift, ctrl, alt, meta) Either extended _DOWN_MASK or old _MASK modifiers should be used, but both models should not be mixed in one event. Use of the extended modifiers is preferred. - int
