Hi Bob,
What is this v8 you're referring to (in terms of QJSEngine I mean)? Can
you explain "it used" further?
It's possible, in many/most cases, to extend or even replace the
built-in JS types in QJSEngine (not QQmlEngine). Either with pure JS
implementations or C++ or a mix. I'm not sure a

Hi Nicholas,
What you want to do is create your custom QOpenGLWidget first (it could
be the bare minimum to start with, even just a header file with the
class declaration). Then in Qt Creator/Designer you want to "promote"
the placeholder QOpenGLWidget to your custom version. If you search o
