However, this forum does look, as feared when I suggested it, very quiet. Does anyone have any Tcl/Tk questions? Whenever I can get online I'll be happy to answer them. Tcl/Tk is kind of my speciality, so I should be able to help with any problems you might have.
If you don't use Tcl, you
should! Check out
http://www.tcl.tk/ - it's free, and it's got to be the fastest and easiest way to develop GUI programs that run on Windows, Unix and Macintosh. It's easier to write portable software in Tcl/Tk than in Java.
Tcl's also great for embedding in your own C or C++ applications so your users can script them.
Tcl's been criticised by Richard Stallman (among others) - but nearly completely unfairly. The accusation that it doesn't scale to large programs is completely unfounded - and just because RMS doesn't like the syntax doesn't mean it's not easy and logical for your users. There's even an object oriented extension - incr Tcl - which makes writing bigger systems a breeze.
Give it a try - you won't be disappointed!
