[Interest] QLineEdit upper case

[pmqt71]

Hi Bo,
as I said, some controls already have a validator so I can't replace it.

I also tried the event filter, but once intercepted, the event is not
modifiable :

...
if (event->type() == QEvent::KeyRelease)
{
      QKeyEvent* keyEvent = static_cast<QKeyEvent*>(event);
       // keyEvent has no method to change the key!
      //...
}
