PySide6.QtDBus

Detailed Description

An introduction to Inter-Process Communication and Remote Procedure Calling with D-Bus.

Introduction

D-Bus is an Inter-Process Communication (IPC) and Remote Procedure Calling (RPC) mechanism originally developed for Linux to replace existing and competing IPC solutions with one unified protocol. It has also been designed to allow communication between system-level processes (such as printer and hardware driver services) and normal user processes.

It uses a fast, binary message-passing protocol, which is suitable for same-machine communication due to its low latency and low overhead. Its specification is currently defined by the freedesktop.org project, and is available to all parties.

Communication in general happens through a central server application, called the “bus” (hence the name), but direct application-to-application communication is also possible. When communicating on a bus, applications can query which other applications and services are available, as well as activate one on demand.

Using the Module

To include the definitions of modules classes, use the following directive:

import PySide6.QtDBus
