I am not sure that I have a "clever" idea, but I can point to similar threads in the past. See ruby-talk #43139 and #41919:

I can also share with you a little insight I got while playing with GUI frameworks in Ruby. Most (I dare say all) GUI frameworks will have a
Timer class which is easy to use and will accomplish what you want.

I have used the one in wxRuby (http://rubyforge.org/projects/wxruby/\) and it works perfectly. Like so:

#... instantiate
     @timer = Wx::Timer.new(self, :timer.id)
     evt_timer(:timer.id) {on_timer}
#...

def on_timer

···

#
   # take action
   #
end

#... use
@timer.start(@delay)

@timer.stop
#...

Does this sound like what you want? I will gladly share the real code (which is more complex) if you are interested.

Thanks,

Shashank,

Thanks for replying and for the thread pointers. I'm not sure if the code
snippets are exactly what I need or not, since I'm not sure exactly what I
need. But, I would be interested to see the code you offered. Thanks for
providing me with a place to start! Also, can you recomend any
Framework(s)? I have no experience with tthem...

Thanks again,

Chuck
