[Development] qt open62541 client connection signals doesn't receive from backend class

[Maurice Kalinowski]

Hi,

Are you sure that the backend is loaded properly? Check QOpcUaProvider::availableBackends() and/or whether the client creation causes any issues.
Furthermore, I assume you have been using the documentation from Open62541 itself? The default build generates a shared library, which needs to be in your PATH to be found on runtime.

As a final comment, your question is rather on using Qt / QtOpcUa, while this list is intended for developing on Qt itself. Hence, let’s move any followup discussion to interest at qt-project.org<mailto:interest at qt-project.org> where user problems are tackled.

BR,
Maurice

Subject: [Development] qt open62541 client connection signals doesn't receive from backend class

Hello,
I'm on a stuck with a problem and some help will be appreciated it.
I've installed open62541 following this tutorial (Building On Windows – Mingw32) and seems like everything are ok, but when I try to connect my own client with a demo opcua server the QOpcUaClient::ClientState(Connecting) is always connecting state (no matter if server is running or not).

Debugging I can see:

-qopen62541backend.cpp:
Open62541AsyncBackend::connectToEndpoint(const QUrl &url) is emitting signals correctly (connected when server is running or disconnected when not) so far I think it's ok.

On other hand, qopcuaclientprivate.cpp:
void pcUaClientPrivate::setStateAndError(QOpcUaClient::ClientState state, QOpcUaClient::ClientError error) seems like should receive the signals from backend class but it doesn't work, so client state still on connecting.

I also tried with other compiler (“Qt 5.11.1 64-bit for Desktop (MSVC 2017)”) and still happen the same.

I'm looking forward for your feedback. Thanks in advance.
Regards.
Berna.
