PySide6DOM 0.1.0

Bring the simplicity of the Web DOM to Python PySide6 Desktop Applications.

Installation

pip install pyside6dom

PySide6DOM bridges the gap between web development and systems programming. It wraps the raw power of the PySide6 (C++/Qt) rendering engine inside the familiar, intuitive Document Object Model (DOM) paradigm used by JavaScript and HTML.

If you know how to build a web page using createElement, getElementById, and appendChild, you already know how to build high-performance, standalone Python desktop applications.

🌟 Why Use PySide6DOM?

• Zero HTML Parsing: This is not a web view or a browser wrapper. It generates native C++/Qt desktop widgets using Python, ensuring maximum performance.
• Familiar Syntax: Uses lightweight helper functions modeled directly after the web DOM (ce() for create element, ge() for get element, ba() for body append).
• Rapid Prototyping: Build user interfaces in seconds without getting bogged down in complex object-oriented boilerplate.
• Educational Bridge: The perfect stepping stone for web developers transitioning into local hardware control, computer vision, and systems engineering.

📂 Repository Structure

This repository includes two learning paths:

• 001_pyside6dom/ (Modular / Production Ready): Separates the heavy GUI engine into a background module (pyside6dom_modular.py) so your main application script remains incredibly clean.
• 002_pyside6dom_single_file/ (Training Wheels): Contains everything in a single script, allowing you to see exactly how the DOM wrappers interact with the raw PySide6 classes under the hood.

🚀 The Code: Web Logic meets Python Power

Look how clean and intuitive building a native desktop app becomes. No complex classes, no confusing layout managers - just straightforward DOM logic.

from pyside6dom import ce, ge, ba, init_window, run_app

# Initialize the Application
init_window("Telemetry Station", width=440, height=520)

# Create a Header (createElement)
header = ce("text")
header.id = "main_heading"
header.textContent = "Telemetry Link Online"
header.style("font-size: 18px; font-weight: bold; margin-bottom: 10px;")
ba(header) # (appendChild)

# Create an Input Field
command_input = ce("input")
command_input.id = "user_input"
command_input.placeholder = "Enter station parameter..."
ba(command_input)

# Create an Interactive Button
submit_btn = ce("button")
submit_btn.textContent = "Transmit Command"

# Define what happens on click
def handle_click():
    txt = ge("user_input").value
    print(f"Transmitting Data: {txt}")

submit_btn.onclick = handle_click
ba(submit_btn)

# Launch the App
run_app()
