Namespace

Xui.Core.Abstract

Assembly

Xui.Core.dll

Controls the window backdrop and chrome style.

public enum IWindow.IDesktopStyle.WindowBackdrop

Fields

Acrylic = 3

Blur-behind backdrop. On Windows 11 uses the Acrylic DWM material (more translucent than Mica). On macOS uses NSVisualEffectView with a transparent title bar and empty toolbar so traffic-light buttons are visible without any other chrome.

Chromeless = 1

No system chrome. The entire surface is client area and the app draws everything.

Default = 0

Standard opaque window with full system chrome (title bar, icon, buttons).

Mica = 2

Translucent blurred backdrop using the Windows 11 Mica material. System caption buttons are kept, but icon and title text are removed. Windows only — use Acrylic for cross-platform blur-behind.

Remarks

Windows: Default creates a standard WS_TILEDWINDOW. Chromeless uses WS_POPUP with no system chrome. Mica and Acrylic use DWM system backdrop APIs (Windows 11+) with system caption buttons but no icon or title text.

macOS: Chromeless maps to FullSizeContentView | Borderless with a transparent title bar and empty toolbar (traffic-light buttons remain, no chrome visible). Acrylic uses NSVisualEffectView with the same transparent-titlebar + empty-toolbar treatment. Mica is a Windows-only concept; prefer Acrylic for cross-platform blur-behind.
