    Default how to add model to different model-delegate

    Hi.
    i have ListView with model in main.qml where is loaded second qml with data. But when i want data from second model they still looking into first model (groupModel) in main.qml. How to get data from itemModel?
    model is in c++. it finish with ReferenceError: datafromItemModelis not defined becouse datafromItemModel is defined in itemModel and he still looking into groupModel

    here is little example:

    main.qml
    Qt Code:
    1. ListView {
    2. id: listView
    3. anchors.fill: parent
    4. model: groupModel
    5.  
    6. delegate: Loader {
    7. source: fileName // fileName from groupModel data
    8. }
    9. }
    To copy to clipboard, switch view to plain text mode 

    item.qml
    Qt Code:
    1. GridView {
    2. model: itemModel
    3.  
    4. delegate: Rectangle {
    5. Text {
    6. text: datafromItemModel
    7. }
    8. }
    9. }
    To copy to clipboard, switch view to plain text mode 

    c++ code
    Qt Code:
    1. QVariant MainModel::data(const QModelIndex & index, int role) const
    2. {
    3. const ItemModel * itemModel= mainDatas.at(index.row());
    4. switch (role)
    5. {
    6. case fileNameRole:
    7. return QString("item.qml");
    8. case itemModelRole:{
    9. return itemModel;
    10. }
    11. default:
    12. return QVariant();
    13. }
    14. }
    To copy to clipboard, switch view to plain text mode

    Do you mean that one model serves data which is instances of the other model?
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.
