qt-kurarin 0.2.2b2

Prototype multi-window Qt reconstruction of Kyukurarin desktop MV effects.

Qt-Kurarin Python Prototype

Qt-powered Kyuukurarin (きゅうくらりん) on your desktop — animated sprites in sync with the music

📖 English 📖 简体中文(大陆) 📖 日本語

This is a PyQt6 reconstruction track for validating the core effect of the original project:

• multiple independent top-level windows
• transparent backgrounds
• timeline-driven movement
• fade in / fade out
• always-on-top presentation

The current build reads:

• data/script.txt
• resources/audio.mp3
• resources/*.png

💡 Generate your own wallpaper: wallpaper/gen_wallpaper.py

Platform Notes

--hide-taskbar-button

Technical breakdown of how this flag behaves across operating systems:

Windows ✅ Reliable. Sets the Tool window flag, which maps to the Win32 WS_EX_TOOLWINDOW extended style. The window will not appear in the taskbar or Alt+Tab list, but remains always-on-top.

macOS 🟡 Likely works, not guaranteed. When combined with WindowStaysOnTopHint, macOS treats the window as a floating utility panel, which typically lacks a Dock icon. However, on some macOS versions, a single Tool window may still appear in the Dock.

Linux/Wayland ❌ Unlikely to work. Wayland compositors control taskbar behavior independently — KWin (KDE) ignores the Tool flag entirely, GNOME/Mutter partially ignores it, and wlroots-based compositors (Hyprland, Sway) generally ignore it as well.

Linux/X11 🟡 Depends on the window manager. KWin respects the Tool flag and hides the taskbar entry. GNOME/Mutter partially respects it. Tiling WMs (i3, bspwm) have no traditional taskbar concept, so the flag has no visible effect.
