[QtonPi] Windowed Opengl ES Program

[Eden Harris]

Hi.

I have been experimenting around getting Qt to compile for the Raspberry
Pi. I was able to eventually able to get Qt to compile and run some of the
example programs including some of the opengl ones. I was disappointed that
everything was fullscreen and found some of the examples glitchey and was
not able to exit without restarting my Pi.

I was then able to successfully compile Qt and some of the examples using
the -xcb and -qpa xcb config options(plus a bit of extra tweaking) which
produced windowed programs instead of fullscreen.

When I tried to run some of the opengl example programs with the windowed
Qt I get this error
"Can't find EGLconfig, returning null config
unable to find an x11 visual which matches egl config 0
Cannot initialize EGL"

Is it possible to run windowed opengl es apps on the Pi with Qt? If so,
what can I do to get his to work?
