Hi!

In Ruby Tk, how to make something happen periodically, while the user
does not touch the button, menu, etc.?

Thanks!

Go to <http://rubykitchensi... and search on "tktimer".

Let me recant on that. It's better to go to Google and search "ruby
+tktimer". This finds a lot more stuff. I also recommend the
following link

http://www.ruby-lang.org/cgi-bin/cvsweb.cgi/ruby/ext/...

There you will find links to tktimer.rb, tktimer2.rb, and tktimer3.rb
-- these are examples of the use of the TkTimer class. It's also
possible that you might find

http://raa.ruby-lang.org/project/...

and

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-t...

useful.

Works like a charm, once I know the keyword, things went smoothly.
Thanks!

That said, do you know about proc in the arguments for TkTimer's start
method / parameter, where its result goes?

Thanks!

No, I'm sorry, but I don't know where the result of a block passed to
TkTimer#start goes. In my own work, I have always written these
blocks for their effects, not their results. IMO you shouldn't rely
on the results such blocks. Remember: "effect" can include
modifications to the state of objects visible within your own code.
