public class DragSourceEvent extends EventObject
DragSourceDragEvent and
DragSourceDropEvent.
DragSourceEvents are generated whenever the drag enters, moves
over, or exits a drop site, when the drop action changes, and when the drag
ends. The location for the generated DragSourceEvent specifies
the mouse cursor location in screen coordinates at the moment this event
occurred.
In a multi-screen environment without a virtual device, the cursor location is
specified in the coordinate system of the initiator
GraphicsConfiguration. The initiator
GraphicsConfiguration is the GraphicsConfiguration
of the Component on which the drag gesture for the current drag
operation was recognized. If the cursor location is outside the bounds of
the initiator GraphicsConfiguration, the reported coordinates are
clipped to fit within the bounds of that GraphicsConfiguration.
In a multi-screen environment with a virtual device, the location is specified in the corresponding virtual coordinate system. If the cursor location is outside the bounds of the virtual device the reported coordinates are clipped to fit within the bounds of the virtual device.
