main.cpp
int main(int argc, char* argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc,argv);
QQmlApplicationEngine engine;
BlueToothdevice d;
engine.rootContext()->setContextProperty("device", &d);
qDebug()<<"main thread:"<< QThread::currentThreadId();
engine.load(QUrl(QStringLiteral("qrc:/assets/main.qml")));

}
BlueToothdevice.h
class BlueToothdevice : public QObject { balabalabala }
BlueToothdevice.cpp
balabalabala
main.qml
...
Text {
id: bloodglucoseText2
text: device.bdsugar
font.pixelSize: 6 * dpi
}
...
how can I move object "d" defined in main.cpp to another thread? I still want to use object "d" without changing.
Define properties and invocable methods in your Qt class.
// Define the property bdsugar, accessible from Qml
Q_PROPERTY(bdsugar READ getBdSugar WRITE setBdSugar NOTIFY on BdSugarChanged)
// Define the method bdsugar, callable from Qml
Q_INVOKABLE QString bdsugar( return my_bdsugar; ) const;
But it is not necessary to move the object d to another thread (Or I did not understood the question).
