Re: [SailfishDevel] ListModel sorting in QML
I had similar situation in the past. Data was coming from web, but I needed to rearrange it for QML lists to work. What I found useful and working was to just generate a new model in JavaScript (based on empty ListModel if I recall correctly). I had only a couple of dozens of data and it was changing once or twice during app use sessions. So creating a fresh model from scratch was not a problem at all. Cheers, Artem.

Ok, thanks I will create my own model with sorting capabilities Antoine - Mail original - De: "Andrey Kozhevnikov" À: devel@lists.sailfishos.org Envoyé: Dimanche 17 Novembre 2013 14:05:39 Objet: Re: [SailfishDevel] ListModel sorting in QML afaik the use of JSONListModel not intended the sorting functions. you need to make own model and sort json data before pushing it to model.

Re: [SailfishDevel] ListModel sorting in QML
afaik the use of JSONListModel not intended the sorting functions. you need to make own model and sort json data before pushing it to model.

[SailfishDevel] ListModel sorting in QML
Hi, I have a ListView which loads a model from JSON with JSONListModel. The model contains items and category ids, but is not sorted by category. What I wand to do is to display the items sorted by categories in the ListView. I have put a section.property in the ListView but it is working only half as expected because it is not sorting the model. For instance, if my model content is: Item1 - Category1 Item2 - Category1 Item3 - Category2 Item4 - Category3 Item5 - Category3 Item6 - Category1 Then my ListView will display: Category1 Item1 Item2 Category2 Item3 Category3 Item4 Item5 Category1 Item6 Of course I would like Item6 to be set between Item2 and Item3. How is possible to do that in QML? I would like to avoid manually iterating on all the items to re-order. Thanks, Antoine ___ SailfishOS.org Devel mailing list
