A Boolean value that indicates whether the window automatically displays views that need to be displayed.
The value of this property is true when the window automatically displays views that need to be displayed; otherwise, false. If autodisplay is false, the window or its views must be explicitly displayed.
Automatic display typically occurs on each pass through the event loop.
Passes a displayIfNeeded message down the window’s view hierarchy, thus redrawing all views that need to be displayed, including the frame view that draws the border, title bar, and other peripheral elements.
