The 4.1 designer lets you create actions. I can assign icons to the actions and then use them in the menu and toolbar. What does an action accomplish that a signal from a button, "clicked()" to a slot "handleClick()" doesn't do. The docs on QAction leave a lot to be desired. Does the action aid in the implementation of undo?

I guess I am trying to get a grasp of the intent of QAction and QActionGroup.
