PySide6.QtWebChannel.QWebChannelAbstractTransport

class QWebChannelAbstractTransport

Communication channel between the C++ QWebChannel server and a HTML/JS client.

Details

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.
