\title Undo Framework
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.
