Detailed Description

Users of the QWebChannel must implement this interface and connect instances of it to the QWebChannel server for every client that should be connected to the QWebChannel . The Qt WebChannel Standalone Example shows how this can be done using Qt WebSockets .

Note

The JSON message protocol is considered internal and might change over time.
