TypeError: Can't call meta function because I have no idea how to handle QRemoteObjectSourceLocation

[Uwe Kindler]

Hi,

I use QtRemoteObjects with PySide6. Everything works fine and I have no problem connecting to remote objects but I have a problem connecting a slot to the QRemoteObjectRegistry.remoteObjectAdded(const QRemoteObjectSourceLocation &entry) signal because the type QRemoteObjectSourceLocation is not known in PySide 6.

This is my code:

self.m_Host = QRemoteObjectHost(QUrl('local:server'), QUrl('local:registry'),
            QRemoteObjectHost.BuiltInSchemasOnly, self)
self.m_Host.registry().remoteObjectAdded.connect(self.onRemoteObjectAdded)

@Slot(tuple)
def onRemoteObjectAdded(self, loc  : Tuple[str, PySide6.QtRemoteObjects.QRemoteObjectSourceLocationInfo]):
    print("onRemoteObjectAdded")
    return

If I execute the code, I get the following error:

TypeError: Can't call meta function because I have no idea how to handle QRemoteObjectSourceLocation

In C++ there is not problem connecting to the signal and the type QRemoteObjectSourceLocation is defined as follows:

typedef QPair<QString, QRemoteObjectSourceLocationInfo> QRemoteObjectSourceLocation;
Q_DECLARE_METATYPE(QRemoteObjectSourceLocation)

If I look into the provided QtRemoteObjects.pyi file, I can see, that QRemoteObjectRegsitry is defined as follows:

class QRemoteObjectRegistry(PySide6.QtRemoteObjects.QRemoteObjectReplica):

    remoteObjectAdded        : ClassVar[Signal] = ... # remoteObjectAdded(QRemoteObjectSourceLocation)
    remoteObjectRemoved      : ClassVar[Signal] = ... # remoteObjectRemoved(QRemoteObjectSourceLocation)
    def addSource(self, entry: Tuple[str, PySide6.QtRemoteObjects.QRemoteObjectSourceLocationInfo]) -> None: ...
    def initialize(self) -> None: ...
    def pushToRegistryIfNeeded(self) -> None: ...
    @staticmethod
    def registerMetatypes() -> None: ...
    def removeSource(self, entry: Tuple[str, PySide6.QtRemoteObjects.QRemoteObjectSourceLocationInfo]) -> None: ...
    def sourceLocations(self) -> Dict[str, PySide6.QtRemoteObjects.QRemoteObjectSourceLocationInfo]: ...

The signal remoteObjectAdded is there but there is no QRemoteObjectSourceLocation type. So is this a bug or is there any way to connect to this signal in Python?

Thank you.
