How to Integrate OpenGL and Qt?

Question

I'm working on a small project and I need to use OpenGL and Qt.

I'm a newbie with both libraries, so I need a good tutorial that illustrates how to use both of them together.

Is it better to work with OpenGL in Qt Creator or to use the Qt Visual Studio Plug-in?

You'll be using QGLWidget a lot! Here you go:

Of all those, maybe this is the best one to start: Hello GL Example. If you prefer using Qt Quick instead of Qt Widgets, check these posts:

• Integrating custom OpenGL rendering with Qt Quick via QQuickFramebufferObject
• Scene Graph - OpenGL Under QML

If you want a higher-level 3D API than OpenGL, as o Qt 5.7 Qt 3D became stable.

As for the IDE I suggest using Qt Creator. It works out of the box on Windows and the syntax highlighting and autocomplete are comparable to Visual Studio.
