+To create a better video watching and gaming experience, you can use the immersive window feature to hide the system windows, including the status bar and navigation bar. This feature is available only for the main window of an application. Since API version 10, the immersive window has the same size as the full screen by default; its layout is controlled by the component module; the background color of its status bar and navigation bar is transparent, and the text color is black. When an application window calls **setWindowLayoutFullScreen**, with **true** passed in, the component module controls the immersive full-screen layout of the status bar and navigation bar. If **false** is passed in, the component module controls the non-immersive full-screen layout of the status bar and navigation bar.
