Detailed Description

This type of action is used to show undo or redo actions in the menu or in the toolbars.

This action will keep itself up to date and change the text based on the undo history, plus it will disable itself when there is nothing to undo/redo. You will typically need two instances of this action per view (e.g. the mainwindow).

    new KUndoRedoAction( KUndoRedoAction::Undo, view->actionCollection(), m_history );
    new KUndoRedoAction( KUndoRedoAction::Redo, view->actionCollection(), m_history );

Note that there is no need to connect or even keep a reference to the object as all work is done automatically.

Note: you might want to use the QUndo framework instead. It didn't exist when K3Command was written.
