Shared rendering class

I'm working on an app using OpenGL and FBOs. The FBOs need to use the same basic rendering code as the main window, so I'm left with two choices:

Code:

---

MyRenderer: public QGLWidget, private CoreRenderer
{
}
-OR-
MyRenderer: public QGLWidget
{
private:
  CoreRenderer renderer;
}

---

The same options also exist for the FBO class.

Will Qt care which way I do it? And if not, which way would work nicest with Qt?

Provided that CoreRenderer doesn't inherit QObject, Qt won't mind.

I'll go with the inheritance, then. The renderer class doesn't need to use QObject for anything, so there shouldn't be any problems.

Thanks for the fast response :)
