DragSourceDragEvent

public DragSourceDragEvent(DragSourceContext dsc,
 int dropAction,
 int actions,
 int modifiers)

Suppressed: Constructs a 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.

Parameters:

dsc - the DragSourceContext that is to manage notifications for this event.

dropAction - the user drop action.

actions - the target drop action.

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.

DragSourceDragEvent

public DragSourceDragEvent(DragSourceContext dsc,
 int dropAction,
 int actions,
 int modifiers,

Parameters:

dsc - the DragSourceContext associated with this event.

dropAction - the user drop action.

actions - the target drop action.

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.

x - the horizontal coordinate for the cursor location
