| \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. |
