Determine signals connected to a given slot in Qt

I think Qt stores the slots a given signal is connected to, so that when you emit it all receivers are called, therefore you can access the list of receivers: For debugging purposes, you have: void QObject::dumpObjectInfo () Dumps information about signal connections, etc. for this object to the debug output. This function is useful … Read more

QT : Templated Q_OBJECT class

It is not possible to mix template and Q_OBJECT but if you have a subset of types you can list the slots and signals like this: class SignalsSlots : public QObject { Q_OBJECT public: explicit SignalsSlots(QObject *parent = 0) : QObject(parent) {} public slots: virtual void writeAsync(int value) {} virtual void writeAsync(float value) {} virtual … Read more

C++ signal to QML slot in Qt

You should use Connections in this case (maybe it’s the only way to connect). Put your object myObj to QML file by setContextProperty qmlVectorForm->rootContext()->setContextProperty(“YourObject”, myOb); Your signal is finishedGatheringDataForItem(QString signalString) In QML file, add Connectios likes below: Connections { target: YourObject onFinishedGatheringDataForItem: { qmlString = signalString } }
