Did you read the manual section I referenced, where it discusses callbacks? The problem is that you need to make the function referenced by the callback static, so it can not be a member function as such, they way you have it. You can make a static member function that redirects to a non-static member function of course, and this is what fluid does. Try generating a simple worked example with fluid and see how it directs all the callbacks via static members that then call the non-static members to do the actual work. That's is what you need to do too. It looks inefficient but is usually not that bad, as the compiler will generally inline a lot of that code, making it less of an overhead than you might otherwise think. Also, as a general point - please don't email me direct, always use the mailing lists. I have enough to do as it is and extra uninvited interruptions make it less likely that I will respond...
