No general objections, but this needs to be #ifdef, as it breaks the build with Qt configuration where there is no OpenGL support. Symbian is one of those platforms where OpenGL is not available.

Thanks for the review. :)

I didn't find any macro or global define on Qt's 4.7 documentation to handle this, so what I did was just to ensure that we are not building on Symbian.

Is that ok?

I'm sorry, I should've been more specific :(. I didn't mean to disable OpenGl for S60 but when it's not enabled in Qt in general. S60 was just an example.

For example it's not unusual that Qt fo Embedded Linux is compiled without OpenGL support, too.

You can verify that OpenGL support is available in the .pro file using

contains(QT_CONFIG, opengl) {
    do opengl things
}

In addition there's a QT_NO_OPENGL define set when Qt is configured without OpenGL support.

I'm sorry that I didn't understand it correctly at first place. :)

Thanks for the tips! I didn't find this QT_NO_OPENGL define documented anywhere besides Qt src itself, so I sticked to the .pro approach.
