[Development] QML and QAbstractListModel

[Johan Thelin]

Sorry for top-posting. I'm writing from my phone.

I've had a class like this for a project of mine. It exposed signals for
adding, removing and changing rows as well as the count, data and setData
methods.

This helped me peek and poke at a QAbstractLisaModel from JavaScript.

Cheers,

Johan
