property bool UsesPerPixelOpacity { bool get(); void set(bool value); };public bool UsesPerPixelOpacity { get; set; }member this.UsesPerPixelOpacity : bool with get, setPublic Property UsesPerPixelOpacity As BooleanProperty Value
true if using per-pixel opacity; otherwise, false.
Remarks
By enabling per-pixel opacity, the system no longer draws the non-client area.
The opacity is used when the window is drawn on the desktop (it represents a final rendering step and does not appear as a contributor to property values such as Opacity).
UsesPerPixelOpacity applies only to top-level windows.
