IFAZ Widget Toolkit — widgets Python con temática táctico-militar sobre pywebview

ISKG

IFAZ Widget Toolkit — Python GUI framework with IFAZ theme

---

ISKG renders native-looking widgets as HTML/CSS/JS inside a native window via pywebview.

No browser, no HTTP server — just a Python process and a lightweight WebView.

Features

• 30+ widgets: Button, Entry, ComboBox, Slider, ProgressBar, Canvas, TreeView, DataGrid, Knob, Gauge, Notebook, MenuBar, and more.
• Layout engines: pack, grid (with sticky + weights), place.
• Theming: 5 built-in themes (ifaz, amber, green, blue, light), CSS variable system.
• Cross-platform: Linux, Windows, macOS (same codebase).
• Zero HTTP: No server, no ports, no browser tabs — just a window.
• JS bridge: Bidirectional Python ↔ JavaScript calls for real-time UI updates.
• .tooltip on every widget: Set a tooltip via property or config().
• after() timers: Cancelable timer objects with .cancel() and .running.

Comparison — lightness & footprint

Framework	Dependencies	Installed size	Own code	Notes
Tkinter	0 (stdlib)	~1 MB	—	No modern widgets, dated look
Remi	1 (bottle/werkzeug)	~2 MB	~15 KLoC	Browser-based, needs a tab
ISKG	1 (pywebview)	~2 MB	~6 KLoC	Native window, modern widgets
PySimpleGUI	1 (tkinter/Qt)	~5 MB	~100 KLoC	Wrapper, not a framework
Dear PyGui	0 (bundled)	~10 MB	~80 KLoC	GPU-accelerated, no native look
Kivy	SDL2, GLEW, etc	~15 MB	~200 KLoC	Own UI language, heavy
wxPython	wxWidgets	~20 MB	~150 KLoC	Native look, complex build
PyQt/PySide	Qt (~100 MB)	~50 MB	~500 KLoC	Full-featured, huge size
NiceGUI	FastAPI + uvicorn + Vue	~30 MB	~50 KLoC	Browser-based, async
Flet	Flutter SDK	~200 MB	—	Requires Flutter toolchain

ISKG ranks 3rd in lightness — only Tkinter and Remi are smaller. Among frameworks that render in a native window (not a browser tab), ISKG is the lightest after Tkinter.
