Changes to Qt WebSockets

Qt 6 is a result of the conscious effort to make the framework more efficient and easy to use.

We try to maintain binary and source compatibility for all the public APIs in each release. But some changes were inevitable in an effort to make Qt a better framework.

In this topic we summarize those changes in Qt WebSockets, and provide guidance to handle them.

Breaking public API changes

This section contains information about API changes that break source compatibility.

QWebSocketServer::socketDescriptor(), QWebSocketServer::setSocketDescriptor()

In Qt 6, you should use QWebSocketServer::socketDescriptor() and QWebSocketServer::setSocketDescriptor() to access the underlying socket descriptor of type qintptr. They mirror QTcpServer::socketDescriptor() and QTcpServer::setSocketDescriptor(), and replace the now deprecated nativeDescriptor() and setNativeDescriptor() methods.
