Hi, Just scanned thru the wxruby-swig source, looked so much better compared to the wxruby-0.4.0, for one, now the on_xxx functions are available and can be overloaded by child classes. I will try to play more with it and see what I can come up with. I am actually in the process of learning Visual C++.NET using this book called "Visual C++ .NET Bible". Just after I found out about wxruby, I was thinking that it will be cool if I could make some tutorials based on the demo apps in the book. Showing how WxWidgets are similiar to MFC, and how wxruby makes it easier to program than C++. Cheers, Phuah Yee Keat
