How to build a cross platform GUI with Python
summary
Builds a working cross‑platform GUI from a single Python codebase using the toga widget toolkit and briefcase packaging tools, demonstrating development (briefcase dev), full packaging (briefcase create/build/package) and deployment to desktop, iOS, Android and web. The demo app shows text inputs, a matplotlib histogram driven by numpy, tab navigation, and a map that requests GPS permissions and recenters — it runs natively on each platform but notes limits: iOS builds require macOS, signing is manual for some targets, and SciPy/OpenCV lack iOS wheels.
