Make it easier to read and write model data outside of a delegate

    XMLWordPrintable

    Details

      Description

      When in a delegate, it's easy to read (and have bindings to) and write model data:

      Slider {
          value: model.someValue
          onMoved: model.someValue = value
      }
      

      If you want to have an editor that is equivalent to a delegate but only shows the current item, it's less convenient:

      Slider {
          value: view.currentIndex !== -1 ? view.model.data(view.model.index(view.currentIndex, 0), Model.SomeValueRole) : 0
          onMoved: view.model.setData(view.model.index(view.currentIndex, 0), value, Model.SomeValueRole)
      }
      

      This assumes that you have an enum for the roles and that that enum is exposed to QML via Q_ENUM. It also doesn't react to changes to the current model data.

      We should make this more convenient somehow.
