qtzmq 0.1.4

Qt-friendly ZeroMQ bindings for PySide and PyQt applications

qtzmq

Qt-friendly ZeroMQ bindings for Python.

qtzmq provides lightweight wrappers around ZeroMQ sockets that expose incoming messages as Qt signals.
It is designed for PySide6 and PyQt applications that need to consume streaming data without blocking the GUI thread.

The library handles:

• ZeroMQ socket setup
• background worker threads
• safe interaction with the Qt event loop
• clean message dispatch through Qt signals

Why qtzmq?

When building Qt applications that use ZeroMQ, developers usually need to write the same boilerplate:

• create a ZeroMQ socket
• run a background thread
• receive messages
• emit Qt signals
• manage shutdown safely

qtzmq provides a small reusable layer that removes this boilerplate and exposes a simple API.

API Overview

qtzmq manages ZeroMQ endpoints through a global stream registry.

Applications create a messaging endpoint once and access it anywhere in the Qt application.

Create streams

subscribe(name, address)

publish(name, address)

request(name, address)

reply(name, address)

Access streams

stream(name)

Widgets and components can then attach handlers or send messages using the returned stream object.

This design allows multiple Qt widgets to consume the same ZeroMQ stream without managing sockets or threads.

Installation

pip install qtzmq
