I think you might be interested in this:

You have the source code and all, it's a good way to learn new things :-)

Hello Alan,
thank you.

The customer don't want QML because for some strange reason he don't want to
use it. I don't know much more, anyway I have to adapt..
And of course we cannot force him to use QML.

I've saw your example but seems that is only for qt5, we are currently using
qt4.8.5
Let's see if I can find something on the web..

However, I am waiting for some good soul who wants to help me  :-)
Regards
Simone

Depending on what "political reasons" means, you could do stuff like

QQmlComponent c;
c.setData("import MyApp 0.1; import QtQuick 2.2; ListView{model:
MyModel{}; delegate: MyDelegate{}}");

inside your C++ implementation. MyModel being your custom QAbstractItemModel
and MyDelegate being a custom QQuickItem written in
C++ for the delegate. If you're willing to use private APIs (which has
massive drawbacks when you don't bundle a specific Qt build with your
app) you can even skip the component and create a QQuickListView directly.

A QWebView would also be fairly easy, but HTML is even worse than QML for
most of the reasons that people want to ban QML.

If you really can't use QML or QtQuick, you can implement such a widget with
QtWidgets but there's no real help for that. Just do all your own touch
handling and painting and it's still easier than a raw opengl app,
