FastWindow v0.1.0 — Initial Release 🚀

🎉 Version 0.1.0: Professional Native Window Management for Java

Release Date: 2026-05-02
Tag: v0.1.0

✨ Features

🛡️ Flicker-Free Resizing (The "Strobe Fix")

  • Native Erase Hook: Intercepts WM_ERASEBKGND to eliminate the white/black flashes during window resizing.
  • Color Synchronization: Syncs the native Win32 background color to your Java UI for seamless visual transitions.
  • Fluid UI Scaling: Optimized WM_WINDOWPOSCHANGING strategy allows the OS to stretch content while Java repaints, creating a liquid-smooth experience.

📏 Kernel-Level Geometry Control

  • Hard Constraints: Enforces minimum and maximum window sizes directly in the Windows kernel via WM_GETMINMAXINFO.
  • Zero Jitter: Eliminates the "snap-back" effect seen with standard Java setMinimumSize.
  • Maximize Toggle: Native control over the window maximize button and functionality.

🏗️ Architected for the FastJava Ecosystem

  • Handle Provider: Acting as the core "identity" provider, FastWindow captures and exposes the stable HWND handle needed by FastTheme and FastOverlay.
  • AWT Native Bridge: Uses the standard JAWT interface for reliable, low-overhead native window access.
