[Interest] How to use QOpenGLWidget from Qt Creator

[Nicholas Yue]

Hi,

I used designer to create a QOpenGLWidget on a MainWindow

I can retrieve the widget via findChild<QOpenGLWidget*>()

My understanding is that to leverage the widget, there are a couple of
virtual methods that needs to be overridden e.g. paintGL(), resizeGL(),
initializeGL()

However, the widget I retrieve via findChild() will be the base class
without the overridden methods.

I must be missing something here.

Where can I read up more on how this can be resolved ?

The OpenGL examples I found did not use Qt Creator to create the UI

Cheers
