public class TableDragSourceEffect
extends DragSourceEffect

This class provides default implementations to display a source image when a drag is initiated from a Table.

Classes that wish to provide their own source image for a Table can extend the TableDragSourceEffect class, override the TableDragSourceEffect.dragStart method and set the field DragSourceEvent.image with their own image.

Subclasses that override any methods of this class must call the corresponding super method to get the default drag source effect implementation.

3.3

Method Detail

dragFinished

public void dragFinished(DragSourceEvent event)
This implementation of dragFinished disposes the image that was created in TableDragSourceEffect.dragStart. Subclasses that override this method should call super.dragFinished(event) to dispose the image in the default implementation.

Specified by:
dragFinished in interface DragSourceListener
Overrides:
dragFinished in class DragSourceAdapter
Parameters:
event - the information associated with the drag finished event
See Also:
DragSourceEvent

dragStart

public void dragStart(DragSourceEvent event)
This implementation of dragStart will create a default image that will be used during the drag. The image should be disposed when the drag is completed in the TableDragSourceEffect.dragFinished method. Subclasses that override this method should call super.dragStart(event) to use the image from the default implementation.

Specified by:
dragStart in interface DragSourceListener
Overrides:
dragStart in class DragSourceAdapter
Parameters:
event - the information associated with the drag start event
