HI and welcome to devnet,
inside your class
uiis private so you cannot access to it outside your class.
If you need to change something outside your class you have to define a public method that changes your UI and call it from outside your class.Usually you can to it also using signals/slots
Once your problem is solved don't forget to:
- Mark the thread as SOLVED using the Topic Tool menu
- Vote up the answer(s) that helped you to solve the issue
