Hi All,
Currently i am upgarding the QT platform from QT3.X to QT5.3.2 .
When i used QT3.X, I can rotate the screen to use transformed:Rot90 command, but in QT5.3.2, i can't rotate the screen. How do i do for rotating the screen to Rot 90?
Regards

Hi and welcome to devnet,

What platform/OS are you talking about ?

On a side note it's Qt, QT stands for Apple QuickTime
