# Networking Qt 6 comes with a rich set of networking classes on the C++ side. There are for example high-level classes on the HTTP protocol layer in a request-reply fashion such as `QNetworkRequest`, `QNetworkReply` and `QNetworkAccessManager`. But also lower levels classes on the TCP/IP or UDP protocol layer such as `QTcpSocket`, `QTcpServer` and `QUdpSocket`. Additional classes exist to manage proxies, network cache and also the systems network configuration. This chapter will not be about C++ networking, this chapter is about Qt Quick and networking. So how can I connect my QML/JS user interface directly with a network service or how can I serve my user interface via a network service? There are good books and references out there to cover network programming with Qt/C++. Then it is just a manner to read the chapter about C++ integration to come up with an integration layer to feed your data into the Qt Quick world. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
