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' (http://www.qtcentre.org/threads/57302-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
