@jeanmilost said in ListView - How to refresh rows which content changed without slowdown?:

view.model.dataChanged(view.model.index(0, columnCount - 1), view.model.index(rowCount - 1, columnCount - 1));

So you are emiting dataChanged from QML? That seems like a bad practice, why can't you do that in the model?

Ok, I think a clean and rebuild of the whole project did the trick.

I always forget when I don't use it for sometimes. When something is doing weird with Qt you have to clean, qmake or rebuild to get everything in order.

I will tag this issue as solved !
