[Qt-interest] Undo Action

[Ankit Agarwal]

Hi,
I have an application that has a graphics scene. Most of the operations are
done on the graphics scene.
Actions are like, changing the state of the graphics item, adding new
graphics item, showing and hiding graphics item.

My requirement: I need to implement Undo actions in the application. The
user can go back upto 3 actions he performed.

How can i achive this?
