The code you have shown here ought to work. The code you originally
posted using currentItemChanged ought to work.

The fault is probably in some code that you are not showing us. What
is "lista"? Is it really a pointer to your user interface QListWidget,
or is it just some local variable?

I suggest you post a complete minimal compilable example that
demonstrates your problem.
