Using OpenGL with Qt

[Flurite]

I am currently looking into developing some games in C++, and OpenGL seems to have a great library and API for making games. Currently, I am using the Qt Creator IDE and wondering how to incorporate the OpenGL API into Qt Creator.

I looked up some tutorials, but haven't really seen many examples and such. All I know right now is that by typing "opengl" into the "QT += " part in the .pro file of a Qt project, you include the opengl API (I think). I also found out that there is a QGL library that is supposed to be related to OpenGL.

I am pretty confused and new to this kinda stuff. Any ideas/help?

Thanks in advance.

Hi there,

Here are some links that can point you in the good direction:

Sorry I couldn't be of more help.

All the best,

Thanks, I will look into those resources.

This is a bit unrelated to the current topic, but in a tutorial that introduces you to using OpenGL with Qt, it mentions promoting a widget to a class using the "Promote to..." option when right clicking the widget.

What happens when you promote the QWidget to your class desired? Do the properties remain?

Suffice to say, I don't think that Shamus would recommend using Qt for any sort of real-time OpenGL application.
