|
|
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.
