Ok, I got help on IRC from "sletta" a few days ago and I have a solution available on Github for those that end up in this mailing list post when searching [1] (that is in the mailing list archive). The answers below are valid for Qt 5.3 and QtQuick 2.3 which I have used in my development probably some earlier versions as well and maybe some upcoming versions. To answer my questions in my first post:
1) Yes, the repeater only increases index.row() (see answer to #2 below) 2) Yes, QtQuick / QML only supports Lists and not the QAbstractTableModel. I solved this by mapping my implementation of the QAbstractListModel to the underlying std::vector of std::vector by introducing two helper functions (index.row() mapped to row and column). [2] 3) I was wrong, I had to change in the c++ code (see answer to #2 above) [1] https://github.com/christofferholmstedt/MineSweeper/releases/tag/v0.1.1 [2] https://github.com/christofferholmstedt/MineSweeper/blob/development/boardmodel.cpp#L151 Hope it can help someone in the future. -- Christoffer Holmstedt 2014-09-15 15:34 GMT+02:00 Christoffer Holmstedt < christoffer.holmst...@gmail.com>: > Hi > Just started to learn how Qt works with QtQuick (Qt 5.3.1).
