Good Morning,
I search the net very much but I didn't find any answer to my question.
I have a shell with 2 combos and other widgets, such buttons and labels:
when I select an element in the first combo, the shell should refresh
itself (with all the component previously in it) loading some other
values (depending on the value of the first selection) in the second combo.
This behaviour should be repeated every time the user choose a different
value in the first combo, until he pushes the ok button to go to the
next shell.
I don't know how to do this thing, so any help (explanation and pieces
of code should be the maximum) is very very very appreciate.
