public Class TableDropTargetEffect

Class Inheritance
Imports
org.eclipse.swt.graphics.*, org.eclipse.swt.internal.*, org.eclipse.swt.internal.gtk.*, org.eclipse.swt.widgets.*
This class provides a default drag under effect (eg. select, insert and scroll) when a drag occurs over a Table.

Classes that wish to provide their own drag under effect for a Table can extend the TableDropTargetEffect and override any applicable methods in TableDropTargetEffect to display their own drag under effect.

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

The feedback value is either one of the FEEDBACK constants defined in class DND which is applicable to instances of this class, or it must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those DND effect constants.

Feedback:
FEEDBACK_SELECT, FEEDBACK_SCROLL
