Thanks,

I modified the code. Now I cache all the changes inside the qt objects
and "push" the values to the SMProperty inside the overloaded apply()
method (using SetElement(...) ...). The only thing is that I have to
call  pqPropertyWidget::apply();" at the beginning of my overloaded
pqMyPropertyWidget::apply() to make it work.

I'm going to clean all my other sources now...

Thanks again.
