public class TableDropTargetEffect
- extends
DropTargetEffect
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
