Undo FrameworkFiles:
This demo shows Qt's undo framework in action.
Qt's undo framework is an implementation of the Command pattern, which provides advanced undo/redo functionality. To show the abilities of the framework, we have implemented a small diagram application in which the diagram items are geometric primitives. You can edit the diagram in the following ways: add, move, change the color of, and delete the items. © 2008-2011 Nokia Corporation and/or its subsidiaries.
