Standard Widget Toolkit for GTK 3.125.0 · org.eclipse.swt.custom.StyledTextDropTargetEffect

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
