/* this example show how to bind a regexp with a one message / one class methaphor
   using callback on OnMessage method

   it shows also how to bind several regexp in one class using BindMsg method.
   it shows a common usage of user_data callback parameter : using it so pass a pointer on object

   usage :
   launch test_IvyQt
   in another terminal launch ivyprobe '(.*)'
   manipulate slider, see effect on ivyprobe 
   send message in ivyprobe : set col red (or any color) and see effects on test_IvyQt
