Detailed Information — The Deep Dive

This section provides comprehensive technical documentation for every layer of the Pytigon stack. If the Architecture section gave you the forest, this section gives you the trees — every branch, every leaf, every root.

How to Use This Section

Each subsection targets a specific technical domain:

Backend — Django models, views, templates, and the JSONModel extensions
Frontend — Web GUI components, wxPython native controls, mobile interfaces
Communication — HTTP, WebSockets, and the protocols that bridge front and back

Read in order for a complete understanding, or jump directly to the topic you need.

Documentation Conventions

Code examples in this section use the .ihtml template syntax. If you're new to .ihtml, review the Template editor section first.

Python code examples are complete and tested against the current Pytigon release. Where API signatures include type hints, those hints are accurate for Python 3.10+.
