WinUp 🚀

A ridiculously Pythonic and powerful framework for building beautiful desktop applications.

WinUp is a modern UI framework for Python that wraps the power of PySide6 (Qt) in a simple, declarative, and developer-friendly API. It's designed to let you build applications faster, write cleaner code, and enjoy the development process.

Why WinUp? (Instead of raw PySide6 or Tkinter)

Desktop development in Python can feel clunky. WinUp was built to fix that.

Feature	WinUp Way ✨	Raw PySide6 / Tkinter Way 😟
Layouts	ui.Column(children=[...]), ui.Row(children=[...])	QVBoxLayout(), QHBoxLayout(), layout.addWidget(), pack(), grid()
Styling	props={"background-color": "blue", "font-size": "16px"}	Manual QSS strings, widget.setStyleSheet(...), complex style objects.
State Management	state.bind(widget, "prop", "key")	Manual callback functions, getters/setters, StringVar(), boilerplate everywhere.
Two-Way Binding	state.bind_two_way(input_widget, "key")	Non-existent. Requires manual on_change handlers to update state and UI.
Developer Tools	Built-in Hot Reloading, code profiler, and window tools out of the box.	Non-existent. Restart the entire app for every single UI change.
Code Structure	Reusable, self-contained components with @component.	Often leads to large, monolithic classes or procedural scripts.

In short, WinUp provides the "killer features" of modern web frameworks (like React or Vue) for the desktop, saving you time and letting you focus on what matters: your application's logic.

🧊 WinUp vs 🧱 PyEdifice (Reddit User Request)

Feature	WinUp	PyEdifice
🧱 Architecture	React-style + state	React-style + state
🌐 Built-in Routing	✅ Yes (Router(routes={...}))	❌ No built-in routing
♻️ Lifecycle Hooks	✅ on_mount, on_unmount, etc.	⚠️ Limited (did_mount, etc.)
🎨 Theming / Styling System	✅ Global & Scoped themes	❌ Manual CSS injection
🔲 Layout Options	✅ Row, Column, Grid, Stack, Flexbox	⚠️ Mostly Box & HBox/VBox
🎞️ Animations	✅ Built-in (fade, scale, etc.)	❌ None built-in
🔁 Hot Reloading (LHR)	✅ Stable + fast (loadup dev)	⚠️ Experimental, limited support
📦 Packaging	✅ With LoadUp (PyInstaller-based)	❌ Must integrate PyInstaller manually
🧩 Component Reusability	✅ High, declarative	✅ High
🛠 Developer Tooling	✅ DevTools planned, Inspector soon	❌ None yet
📱 Mobile Support	❌ Not yet	❌ Not supported
🧠 Learning Curve	✅ Easy for Python+React users	✅ Easy but less tooling

✅ = Built-in or robust
⚠️ = Partial or limited
❌ = Missing entirely

Core Features

• Declarative & Pythonic UI: Build complex layouts with simple Row and Column objects instead of clunky box layouts.
• Component-Based Architecture: Use the @component decorator to create modular and reusable UI widgets from simple functions.
• Powerful Styling System: Style your widgets with simple Python dictionaries using props. Create global "CSS-like" classes with style.add_style_dict.
• Full Application Shell: Build professional applications with a declarative API for MenuBar, ToolBar, StatusBar, and SystemTrayIcon.
• Asynchronous Task Runner: Run long-running operations in the background without freezing your UI using the simple @tasks.run decorator.
• Performance by Default: Includes an opt-in @memo decorator to cache component renders and prevent needless re-computation.
• Advanced Extensibility:
  • Widget Factory: Replace any default widget with your own custom implementation (e.g., C++ based) using ui.register_widget().
  • Multiple Windows: Create and manage multiple independent windows for complex applications like tool palettes or music players.
• Reactive State Management:
  • One-Way Binding: Automatically update your UI when your data changes with state.bind().
  • Two-Way Binding: Effortlessly sync input widgets with your state using state.bind_two_way().
  • Subscriptions: Trigger any function in response to state changes with state.subscribe().
• Developer-Friendly Tooling:
  • Hot Reloading: See your UI changes instantly without restarting your app.
  • Profiler: Easily measure the performance of any function with the @profiler.measure() decorator.
  • Window Tools: Center, flash, or manage your application window with ease.
• Built-in Routing: Easily create multi-page applications with an intuitive, state-driven router.
• Flexible Data Layer: Includes simple, consistent connectors for SQLite, PostgreSQL, MySQL, MongoDB, and Firebase.
