qt 4.8.2 qpa black screen


#1

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:<div =“post-text” itemprop=“deion”>


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
