      Hello there,
      I am using Qt OPCUA version 5.13.0. I am trying to find a functionality, that would allow me to trigger an event when a node that currently does not exist on the server is created. With the monitoring functionality I can only subscribe to attribute changes of an existing node. In this case, I need to know as soon as the node is created, while it doesn't exist yet. I have found this event functionality:

      https://doc-snapshots.qt.io/qtopcua/qopcuanode.html#eventOccurred
      https://doc-snapshots.qt.io/qtopcua/qopcuamonitoringparameters-eventfilter.html#details

      But I cant seem to find a way to obtain the functionality I am looking for. Is this possible? I know that when using the UA Automation Qt OPCUA library, the functionality is available there (OpcUaId_ModelChangeStructureDataType). I wonder either it here as well in some form.

      I would appreciate all help.
