Subject: [Interest] QOpenGLWidget and text
I've been working on porting a Qt4 GL application to Qt5, using the new
QOpenGL classes instead of the old and deprecated QGL classes.
Some of it was
the qt.conf file.
Or you may use this, which is pretty handy and easy to use:

Hope this helps.

Greetings all,
Having to reuse some piece of very old code, I need to get the low-level handle
on a font - specifically
the HFONT, as we're running on Windows.
In the Qt3 days, there was a method QFont::handle() which was providing this
information, but it
seems it's gone in Qt5.
Having a
())
{ }
};
Then from inside My_Class, no more need for any kind of gl- prefix and
everyone is happy :-)
Or maybe I missed something? For now our only alternative is to use Glew,
can you confirm it works well alongside Qt?
