[plt-scheme] Re: Location of MrEd builtin-class definition files

Hi Matthew,

thanks again for taking the time.

This is really unfortunate, DrScheme (and Scheme in general) is great, but my problem is that I want/need to develop GUI apps. And those need to be polished. :-(

I have seen some amazing stuff in the games collection, and it seems that quite "polished" apps can be produced with DrScheme.

Does it require me to get deeper into the "Framework" to achieve this?

I don't C but when I can stay within Scheme to do it, then so be it.

Best regards

Guenther
