    Hello,

    I’m trying to render some simple qt application, that uses QGraphicsView with
    QGLWidget as a viewport ( slightly modified collidingmice ) on armv7 embedded platform
    ( beagleboard ). Starting application like this:

    collidingmice -platform eglfs

    But screen is always remains dark. ( textures example is working fine ). I nead to somehow intialize eglNativeWindow in EglFs platform code. How can i do that? Thanks in Advance.

    Hi warzon,

    I’m afraid that none of us here are really familiar with eglfs. However I did find the following post (http://comments.gmane.org/gmane.comp.lib.qt.embedded/1393) that suggests you use the function “SimpleGLScreen::defaultRootWindowHandle()” to get a native window handle. I hope that at least helps a little? Sorry I can’t be of more help!

    Thanks,
    Tobias
