Re: [Interest] QQmlEngine: Illegal attempt to connect to PlatformShim(0xb9b2fb58) that is in a different thread than the QML engine QQmlApplicationEngine(0xa17e1494.
I'm still stuck. I don't know how to do this.
To recap: main.cpp make a singleton called platformShim and adds it as a
property to the QQmlEngine.
Then later when trying to use a Connections element to provide a signal handler
I am told
QQmlEngine: Illegal attempt to connect to PlatformShim( that is in a different
thread than the QML engine.
However both of these were created in main().
QQmlApplicationEngine engine;
PlatformShim *shim = PlatformShim::instance();
engine.rootContext()->setContextProperty(QStringLiteral("platformShim"), shim);
I don't know how that error message is correct, or how to work around it.
Any help is appreciated.

Re: [Interest] QQmlEngine: Illegal attempt to connect to PlatformShim(0xb9b2fb58) that is in a different thread than the QML engine QQmlApplicationEngine(0xa17e1494.
The singleton one requires QML to be able to create the instance and own it
doesn't it?
I'd switch to qmlRegisterUncreatableType()

QQmlApplicationEngine(0xa17e1494.
Still having issues... But made some "progress"
So I changed to using qmlRegisterSingletonType("PlatformSupport",
1, 0 "PlatformShim", &getPlatformShim) However when I do I get 1 of 2 errors:
1. Element is not creatable: when trying to declare a signal handler like
PlatformShim { onPushNotificationReceived; {} } 2. Non-existent attached
object: when trying to declare a signal handler (in QML)
PlatformShim.onPushTokenReceived: { }
I also added:
QObject *getPlatformShim(QQmlEngine *engine, QJSEngine *scriptEngine) {
Q_UNUSED(engine)
Q_UNUSED(scriptEngine)
return PlatformShim::instance();
}
and
import PlatformSupport 1.0 to the QML

[Interest] QQmlEngine: Illegal attempt to connect to PlatformShim(0xb9b2fb58) that is in a different thread than the QML engine QQmlApplicationEngine(0xa17e1494.
I get that error when:
main.cpp:
PlatformShim *shim = PlatformShim::instance();
engine.rootContext()->setContextProperty(QStringLiteral("platformShim"), shim);
In a QML file:
Connections {
target: platformShim
onPushTokenReceived: {
pushToken = token
}
}
I thought Connections were ok across threads?
