Detailed Description

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

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.

Member Function Documentation

QWebChannelAbstractTransport::QWebChannelAbstractTransport(QObject *parent = Q_NULLPTR)

Constructs a transport object with the given parent.

[virtual] QWebChannelAbstractTransport::~QWebChannelAbstractTransport()

Destroys the transport object.

[signal] void QWebChannelAbstractTransport::messageReceived(const QJsonObject &message, QWebChannelAbstractTransport *transport)

This signal must be emitted when a new JSON message was received from the remote client. The transport argument should be set to this transport object.

[pure virtual slot] void QWebChannelAbstractTransport::sendMessage(const QJsonObject &message)

Sends a JSON message to the remote client. An implementation would serialize the message and transmit it to the remote JavaScript client.
