Removing/popping items from QUndoStack

[brcain]

Hello,

Is there any way to remove/pop items from a QUndoStack ... starting from an index and everything thereafter?
The reason I need to do this is related to another problem I'm having with redo commands related to item groups (forum post, 'QGraphicsItemGroup and undo/redo error').

Do I need to derive from QUndoStack to implement the behavior? Is this considered "bad form"?

BTW, I know it's possible to remove all items with the clear() method. I don't see how to "pop" an item or two off.

Regards,
Ben

How about not spawning three threads for the same issue?

Yea, bad form for three threads ... was late I guess. My bad
But, I did learn from my attempted work-arounds.
