public Class TableDragSourceEffect

extends DragSourceEffect
Class Inheritance
Imports
org.eclipse.swt.graphics.*, org.eclipse.swt.widgets.*
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.
