[SailfishDevel] Technical question: populating ListModel from C++

[Jarko Vihriala]

Actually, that's the best solution so far. Just make sure you follow the structure of the in qml/js of data inside QVariantList. Playing around QVariant and *List is a bit tricky but once you get the hang of it, it's awesome datatype.

thanks,Jarko

Hi,

Or if you don't want to subclass e.g. qabstractitemmodel, you can always return a QVariantList(or QList) from c++ and expose that sequence to QML. Then use that JS array to populate ListModel.

Hi,

I have done the same thing in my Sailfish learning project. It was way more complicated than I would have liked it to be (or maybe I did it in the wrong way...).

Feel free to have a look at how I implemented it: https://github.com/Ortofta/SilicaNote

The code quality is probably not the best - these are my first baby steps in QT and Sailfish. ;)

Regards,
Markus

Hi,,

Thank you Janne and Jarko, I will take a look on both of these approaches;

> use the QSqlQueryModel in your c++ and expose that to QML ; just like in : http://qt-project.org/wiki/How_to_use_a_QSqlQueryModel_in_QML


> subclassing QAbstractItemModel. See http://qt-project.org/doc/qt-5/qtquick-modelviewsdata-cppmodels.html and http://qt-project.org/doc/qt-5/qabstractitemmodel.html to get started.
