/* 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
