Is there a dedicated mailing list for Ruby Tk?

Not that I know of. Ruby has bindings for TK with the distribution. You  
could  
talk here. I could start a forum if people wanted. Going through google  
groups is kinda a pain, and I like using stickies in forums 🙂

Anyway, what is the question?

Oh, that’s a dangerous question for a noob 😉

I’m looking and playing with the source for the package “ruby-tcltk”.  
I’ll try to order the questions that I have…

i) When asking a question is it best to paste the source code in  
somewhere like [http://rafb.net](http://rafb.net) so that all can see?  
ii) Do people on this mailing list mind attachments containing code?  
ii) With regards to ruby-tcltk  
a) The package has some demos under  
/usr/share/doc/ruby-tcltk-1.8.4/tk/sample/demos-en  
b) Looking at /usr/share/doc/ruby-tcltk-1.8.4/tk/sample/demos-en/widget  
I’m finding it hard to see how to bind a button to “pop-up”  
anotherwidget. (I think that the correct term is “Invoking” or  
“binding”).

If this helps  
jayeola@tp20$ ruby --version  
ruby 1.8.4 (2005-12-24) [i386-linux]

Thanks for the offer and suggestion of starting up a new forum. I think  
that I’d rather stay here as this list is is quite extensive.

I’m poor at English. So I couldn’t understand what you want to know.  
Could you explain it to me in detail?

Most of the time, you should be able to go by with code excerpts under  
40  
lines of code, you can as well put them into the mail body.

Ech, I’m not that Tk savvy, but speaking from general GUI experience,  
what  
you’re describing isn’t really that common, and I’m not surprised the Tk  
samples don’t feature it - use of dialogs, or just hiding / showing  
widgets is more common.

You should be able to add GUI widgets at runtime in event handlers just  
like you do when first creating the GUI, I’d first check if that works  
out  
of the box. If not, you probably need to tell Tk to redo the layout of  
widgets either in the root element, or if it’s possible, just the one  
containing the new widgets. You really need someone Tk-savvy to tell you  
more.
