...hile its doing the processing and output the entire GUI freezes and looks like crap for about 5 seconds. Basically I''m looking for an easy way to avoid this so the end user doesnt freak out and think the program crashed or anything. I found this code in the thread mentioned above: def on_init t = Wx::Timer.new(self, 55) evt_timer(55) { Thread.pass } t.start(100) which would be used in the on_init of the main App. I understand what it is doing (creates a 100ms timer which calls Thread.pass every iteration), but I don''t understand how this can help the problem....

I''ve seen a few e-mails about multithreading with respect to wxruby but nothing recent. Unless I''m mistaken, and that may be, there still appear to be problems. The following code seems to hang my spawned thread in favor of the wxruby event loop: Thread.new do puts "in thread" loop do sleep 5 puts "looping" end end puts "main

Hi, I am trying to use wxruby2-preview (0.0.38) on my intel macbook running os10.4.8. I am having a beast of a time running the examples in the tutorials. The super basic frame example worked but the simple grid tutorial bombs with the following message: ------ [WhiteGhost:~/tmp/wxStff] hjw$ ruby ./grid.rb /usr/local/lib/ruby/gems/1.8/gems/wxruby2-preview-0.0.38-i686-

Team, I am trying to learn a GUI for Ruby and I picked wxRuby. The problem is that I am kind of slow learning this and I now feel frustrated after trying for about at least 7 hours. I am trying to design a simple Sudoku 9x9 grid to display numbers, 1 - 9, using buttons. I posted a question on Ruby forum ruby-talk and a gentleman, Alex Fenton, answered my questions. Alex gave me what appear to be

is it possible to intercept keystrokes using wxruby?

I have a WxRuby application that takes a few inputs from the user and uses that information to search through a large file for matches. The application works very well, with one exception. If I click anywhere in the frame while the application is searching through the long file, the application hangs. Has anyone experienced anything similar to this? Any suggestions on how I can fix this? Thanks
