+
+   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
