PlatformCapability

Runtime feature probe (2.67 F1).

import QWinUI3.Platform · src/platform/QWinUI3/Platform/PlatformCapability.qml

Category: Platform · Library: v2.80 · singleton

← Component index

Extends QtObject.

Example

if (PlatformCapability.mica)
    WindowHelper.backdrop = WindowHelper.BackdropMica
else if (PlatformCapability.blur)
    /* frost / solid fallback */

PlatformCapability.has("tray")
PlatformCapability.degradationHint("mica")

Notes

Honest capability map for Mica / Acrylic / frost blur / tray / WebView2 / SNI. UI should degrade when a flag is false — do not assume Win11 materials on Linux.
