Communication channel between the C++ QWebChannel server and a HTML/JS client. More...
|qmake:||QT += webchannel|
This class was introduced in Qt 5.4.
|QWebChannelAbstractTransport(QObject *parent = Q_NULLPTR)|
|virtual void||sendMessage(const QJsonObject &message) = 0|
|void||messageReceived(const QJsonObject &message, QWebChannelAbstractTransport *transport)|
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.
