C++ signal to QML slot in Qt

You should use Connections in this case (maybe it’s the only way to connect).

  1. Put your object myObj to QML file by setContextProperty

    qmlVectorForm->rootContext()->setContextProperty("YourObject", myOb);
  2. Your signal is

    finishedGatheringDataForItem(QString signalString)
  3. In QML file, add Connectios likes below:

    Connections {
        target: YourObject 
        onFinishedGatheringDataForItem: {
            qmlString = signalString
