    Hi, thanks for the reply ....

    First I rode with QT (IDE) - did not work, then ran from the command line (qmlviewer), also did not work ...

    Both cases the screen is transparent

      Did it display any errors or any messages in your output-box? Could you post them in that case?

        Hi,

        What is your operating system?

        Are you using a physical machine or a virtual machine?

        What is your graphics card?

                Well, i would say the problem is that you've got no graphics-card, but i could be wrong.

                  Qt requires support for OpenGL 2 or higher. If you only have an onboard graphics chip, then you probably don't have this OpenGL support.

                  Try using the non-OpenGL version of Qt instead: Go to http://qt-project.org/downloads and download a package that doesn't contain "OpenGL" in its name.

                      You're welcome. I'll see what i can find but the problem is probably the non-opengl support. Just try it out without open-gl and it should work out fine. Otherwise you still can use QtQuick 1.0 which doesn't support OpenGL by itself.
