          org.eclipse.gef.tools.TargetingTool

                  sk.uniba.euromath.editor.textEditor.tools.TextDragTracker

All Implemented Interfaces:

org.eclipse.gef.DragTracker, org.eclipse.gef.RequestConstants, org.eclipse.gef.Tool

public class TextDragTracker
extends XMLStructureDragTracker

Works like super, but pointer translation is performed to always point into node's text. This is achieved by accepting as target and source editpart only ITextPieceKeeper.
