public class StyledTextDropTargetEffect
- extends
DropTargetEffect
This adapter class provides a default drag under effect (eg. select and scroll)
when a drag occurs over a StyledText
.
Classes that wish to provide their own drag under effect for a StyledText
can extend this class, override the StyledTextDropTargetEffect.dragOver
method and override any other applicable methods in StyledTextDropTargetEffect
to
display their own drag under effect.
Subclasses that override any methods of this class should 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
