Hi guys,

Thanks for answering him, Art! I’ve forgotten what the process is myself, it’s been awhile since I’ve done any C++ programming, nevermind Qt + OpenGL!

Hey Sai, you need to make sure in your .pro file you have this line:
QT = core gui opengl
that tells Qt to use the OpenGL module
You also need to make sure you are linking to the opengl32.lib and glu32.lib
You can right click on the project folder on the left and then click “Add library” Just add both those libraries by pasting in their respective paths.
Hope that helps!

I am coming from a C++ and QT orientation. Happened to run into your page where OpenGL integration with QT is discussed. Great topic.

I tried downloading the code you had shown above into my C++ ready netbeans IDE to see if it would run on its own. Unfortunately, it failed. I believe some OpenGL library for windows is required.

What to install for OpenGL? How? Perhaps that will enable the above code to run.

instead of printf() you could also use qDebug().

printf was not declared in this scope….

#include
helped
and printf seam to be buffered, so you can mention about it in tutorial

thx for tutorial
