    I'm using a QWindow embedded in a QMainWindow using QWidget::createWindowContainer() and it works fine but when I switch to full screen mode the QWindow dissapears. What is the problem? it looks like is left behind the QMainWindow.

      Hi and welcome to devnet,

      You should add which version of Qt you are using as well as OS

        @SGaist thank you. I've tested in Windows 7 and 8.1 with QT MVSC 64 and MINGW and the same happens.

          Can you try to first go full screen and only then create the embedded QWindow ?
