no idea if it is needed, but how about replacing pUndoSet with a smart
pointer like boost::scoped_ptr?

then the next line would become 'pUndoSet.reset(new ...)', if pUndoSet
is not null it will be deleted automatically, and you can get rid of the
delete in the destructor as well.

Muthu, please take a look at:
http://www.boost.org/doc/libs/1_46_0/libs/smart_ptr/scoped_ptr.htm
