@alcinnz Have you ever looked at the VisualAge Smalltalk system by IBM? I think that was a pretty interesting approach at the time. It was very centered around UI design, and attaching actions to the various UI elements.

They tried applying the same approach to other languages later, like Rexx and C++, but especially the last one did not work as well conceptually.

There's GUI design tools today that look somewhat similar to this, but don't really get to the same level and elegance that the original VisualAge Smalltalk system did. At least from how I remember it. It's been a few years...

@alcinnz Seems the web isn't overflowing with info on VisualAge stuff. But I've been able to dig up a few references.

First, it seems it has been continued as the VAST Platform by Instantiations:
#^https://www.instantiations.com/vast-platform/

They have some docs on their website:
#^https://www.instantiations.com/vast-support/documentation/1301/#page/ug/vaug01.html

I also found a quite a bit by searching for VisualAge on the Internet Archive. Some of the more interesting ones I think are these:

• VisualAge for C++ - Visual Programmers Handbook
• IBM Visual Age C++ for OS/2 - Visual Builder User’s Guide
• IBM Visual Age C++ for OS/2 - Building VisualAge C++ Parts for Fun and Profit

These are, as you can see, for the C++ version, but the visual builder parts was similar. It was just more elegant with Smalltalk as you didn't need a compile cycle, and the language lends itself better to this type of dynamic coding.

Hope that helps.
