[Qt-interest] QMainWindow: setWindowTitle() & setWindowIcon() don't work

[Miguel Cardenas]

It was made by hand and found the problem, it was layer related, once it got
fixed everything worked as expected, sorry am trying Qt 4 for first time,
now and after various tests there's no more problem :)

Thanks
