    Description

      QML List view seems not to handle the modelReset signal from its model.

      The video shows the issue. On the left is a QListView, and on the right the qml view. The model is fed a command to reset and emits the correct signals. The QListView responds, but the qml view does not. Items are only repainted when they leave and re-enter the view.

      QListView *listView = new QListView();
      listView->setModel(rootModel);
      listView->show();

      QmlView *view = new QmlView();
      view->setUrl(QUrl( "/path/to/qmlfile.qml" ) );
      view->engine()>rootContext()>setContextProperty( "events_model", QVariant::fromValue( static_cast<QObject*>( rootModel ) ) );
      view->execute();
      view->show();

      import Qt 4.6

      Rectangle {
      width: 490; height: 400;

      ListView {
      model : events_model
      anchors.fill: parent
      delegate : Component
      {
      Item {
      height : 15
      Text

      { text: model.display }

      }
      }
      }
      }
