- \brief This example shows Qt's undo framework in action.
-
- \image undodemo.png
-
- 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.
