Eglfs issuse on buildroot + RPi



  • Hello,
    I'm running Qt5 within a buildroot environment on RPi, without X.
    It works fine but when I use OpenGL the widget is actually rendered "behind" the console.

    I mean, running the gradient example works fine until I press the "Use opengl button". Now I only see the lateral buttons but the rendering window seems to be behind the shell I used to launch the application....

    What might lead to this odd behavior?
    Thanks
    Mark



  • That example uses a QGLWidget combined with some other widget content. That is simply not supported properly on platforms like eglfs (which is used on the Pi too).

    For more details see http://qt-project.org/wiki/i.MX-6

    There is work on-going for a QGLWidget replacement in Qt 5.3. This solution would then be properly supported across all platforms, allowing mixing traditional widgets and GL/Quick areas.
