Description Thomas Bertels 2025-12-13 13:13:19 UTC

SUMMARY
This rule would let the user make some windows minimize to the System Tray widget instead of the Task Manager.

STEPS TO REPRODUCE
1. Open an app
2. Minimize it

OBSERVED RESULT
It minimizes to tray.

EXPECTED RESULT
It minimizes normally.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
KDE Plasma Version: 6.5.3
KDE Frameworks Version: 6.20.0
Qt Version: 6.10.1

ADDITIONAL INFORMATION
The kwin script https://github.com/luisbocanegra/kwin-minimize2tray lets the user minimize apps to tray.
It doesn't support filtering by window title though, which kwin rules already do.

Comment 1 David Edmundson 2025-12-14 23:00:13 UTC

Apps don't minimse to a system tray, they create a system tray and close.

At a kwin level this means completely hiding the window, which is outside the scope of anything window rules should ever support.
