|
---|
| 36 | Qt's undo framework is an implementation of the Command
|
---|
| 37 | pattern, which provides advanced undo/redo functionality.
|
---|
| 38 |
|
---|
| 39 | To show the abilities of the framework, we have implemented a
|
---|
| 40 | small diagram application in which the diagram items are geometric
|
---|
| 41 | primitives. You can edit the diagram in the following ways: add,
|
---|
| 42 | move, change the color of, and delete the items.
