That was why I asked before exactly what do you wanted to do, the wrapper can only track changes made by you, not changes made internally by the other class, and it was not clear for me when you just say "do something when the value on the object is changed" for you can still use the wrapper idea if the changes were not internal. The idea of the wrapper is that you never instantiate the real class, you always instantiate the wrapper, which will act as a delegate of your class, so anything you do to the wrapper class is passed to the real class giving you the chance to intermediate, but of course it can not do anything for changes or accesses made by the real class itself (although you could put a timer in the wrapper to check it's own value against the real class, but that would be ugly and incomplete, only for assigns)

Sorry, but I run out of ideas <g>
