Nested QML Menu from nested QStandardItemModel

PavloPonomarov

Hello. I have a nested model subclassed from QStandardItemModel and filled like this:

/*----MyModel.cpp----*/
for(int row = 0; row < 10; row++){
  setData(index(row,0), "Item"+QString::number(row), Name);
  setData(index(row,0), 0, Value);
  setData(index(row,0), "description of item"+QString::number(row), Description);
  QStandardItem *item = itemFromIndex(index(row,0));
  for(int i = 0; i < 10; i++){
    QStandardItem *subitem = new QStandardItem;
    subitem->setData("SubItem"+QString::number(i), Name);
    subitem->setData(0, Value);
    subitem->setData("Description of subItem"+QString::number(i), Description);
    item->appendRow(subitem);
  }
}

So, to create a Menu from this model I use Instantiator:

import MyModel 1.0 //it is registered in main.cpp

MyModel{
   id:myModel
}

Menu{
  id: topMenu
  title: "Example"
  Instantiator{
     model: myModel
     onObjectRemoved: topMenu.removeItem( object )
     delegate: Component{
         Loader:{
             id: loader
             onStatusChanged: if (status == Loader.Ready) {
                               topMenu.insertMenu( index, item );
                               loader.item.itemModel = model;
                              }
              source: "SubMenuLoader.qml"
         }
     }
  }
}

My problem is that the model I pass to SubMenuLoader.qml is QQmlDMAbstractItemModelData , which means when I create the Instantiator in SubMenuLoader.qml I will only have the current item, there is no property or method to get children of this model item in QML. I also didn't manage to expose items children from C++, because QML won't understand QList<QStandardItem*>. Even after I declared it as metatype it turns into [QVariant(QStandardItem*, ), QVariant(QStandardItem*, ) ...(and so on)]
