QML Signal connect to C++ Signal

fcarney

I have a signal that is emitted by a C++ object that is of "QItemSelectionModel" type. The signal I connect to is "selectionChanged". I have a slot connected to this signal in C++ and can verify that the signal is firing as it updates a C++ function that prints to the console.

I am trying to connect a QML signal to this signal as the documentation says I can do:

ListView {
  id: cell_list
  ~~~

  // update current selection
  signal selectionChanged
  onSelectionChanged: {
    console.log("selectionChanged")
  }

  Component.onCompleted: {
    cell_list.selectionChanged.connect(cells_selectionmodel.selectionChanged)
  }
}

I don't get any errors when running this code, but I never see "onSelectionChanged" fire.

Edit:
To clarify:

cell_list is the ListView in QML
cells_selectionmodel is the QItemSelectionModel exposed to QML

It would help if I were doing it right:

So not doing the other QML and doing this works:

Connections {
  target: cells_selectionmodel
  onSelectionChanged: {
    console.log("selectionChanged from C++");
  }
}
