Hi
I'm creating qt c++ application with Qml GUI. In qml I have object with ListView to display in row object's properties. In header I have declared meta type:
Qt Code: 
  1. Q_DECLARE_METATYPE(QList<QObject*>)
To copy to clipboard, switch view to plain text mode 
QList<QObject*> is being passed to Qml ListView model as slot parameter. User is able to change NewPrice value.
Qt Code: 
  1. ...
  2. function setPriceDetails(model)
  3.     {
  4.         viewPriceDetails.myModel = model
  5.     }
  6. ...
  7. ListView {
  8.             id: viewPriceDetails
  9.             onModelChanged: {
  10.                 parent.height = viewCenyDetails.height + 130
  11.             }
  12.             model: myModel
  13.             delegate: Row {
  14.                 Text { width: 10 }
  15.                 Text { text: model.modelData.ItemNo; width: 10; }
  16.                 Text { text: model.modelData.Description; width: 80; }
  17.                 Text { text: model.modelData.ActualPrice; width: 80; }
  18.                 MyTextInput {
  19.                     text: model.modelData.NewPrice
  20.  
  21.                     onTextChanged: model.modelData.NewPrice= text
  22.                 }
  23.              }
  24.          }
  25. ...
  26. QList<QObject*> dataList;
  27.     while(queryCenaPaliw.next()){
  28.         dataList.append(new ActualPrice(queryCenaPaliw.value(queryCenaPaliw.record().indexOf("ItemNo")).toString(),
  29.                                               queryCenaPaliw.value(queryCenaPaliw.record().indexOf("Description")).toString(),
  30.                                               queryCenaPaliw.value(queryCenaPaliw.record().indexOf("ActualPrice")).toString()));
  31.     }
  32.  
  33.     emit DB_AktualneCenyPaliw(QVariant::fromValue(dataList));
To copy to clipboard, switch view to plain text mode 
On button click ListView model (myModel) is being send as signal parameter to c++ object
Qt Code: 
  1. signal updatePrices(variant model)
  2.  
  3. ...MenuButton {
  4.                 id: btnUpdate
  5.                 text: "Update"
  6.                 height: 46
  7.  
  8.                 onButtonClicked: {
  9.                     root.updatePrices(root.myModel)
  10.                 }
  11.             }
  12. ...

Now question:
How to in c++ work with this model? I would like to use it to update my db data. How to access data in model?
