WebSocket is a web-based protocol designed to enable a two-way interactive communication session between a client application and a remote host. It enables the two entities to send data back and forth if the initial handshake succeeds.
The Qt WebSockets module provides C++ and QML interfaces that enable Qt applications to act as a server that can process WebSocket requests, or a client that can consume data received from the server, or both.
The QML types of the module are available through the
QtWebSockets import. To use the types, add the following import statement to your .qml file:
find_package() command to locate the needed module component in the
find_package(Qt6 REQUIRED COMPONENTS WebSockets)
target_link_libraries(mytarget PRIVATE Qt6::WebSockets)
For more details, see the Build with CMake overview.
To configure the module for building with qmake, add the module as a value of the
QT variable in the project's .pro file:
QT += websockets
