I am very interested in this and would like very much to see how you will do
this at design time. In particular I am interested in how event handlers can
be set at design time. All without C++ reflection of course and using
strictly the C++ standard, since you are confident that this can be done. My
view of event handlers is that any "component" ( see below ) within such a
system should be capable of handling any event generated by any other
component; which is true of both C++ Builder and Managed C++/.NET.

In the sense that one has to do work at run-time when it could be done at
design time. Please notice I said 'most', not all. If you, or anyone else,
could come up with a RAD C++ GUI development environment which works with
98%+ conforming C++ compilers ( Como, gcc, VC++ 7.1, Intel etc. ) and
enables one to easily set properties and events at design time, ala C++
Builder and Managed C++/.NET, I would be very interested in it and would
contribute to it any way that I can if I liked the design. By GUI I also
means the sort of components ( properties and events along with traditional
C++ method-based programming ) which are supported by C++ Builder and
Managed C++. I think non-visual components are also very important and
should be available for design time configuration just as much as visual
components in such a GUI environment.
