The windowControlsOverlay
read-only property of the Navigator
interface returns the WindowControlsOverlay
interface, which exposes information about the title bar geometry in desktop Progressive Web Apps that use the Window Controls Overlay API.
Progressive Web Apps installed on desktop Operating Systems can opt-in to the Window Controls Overlay feature by using the window-controls-overlay
value in the display_override
web app manifest member.
Doing so hides the default window title bar and gives the app access to the full area of the app window.
