setSimpleFullscreen
fun setSimpleFullscreen(fullscreen: Boolean): ERROR CLASS: Symbol not found for js.promise.Promise<ERROR CLASS: Symbol not found for js.core.Void>(source)
On macOS, Toggles a fullscreen mode that doesn’t require a new macOS space. Returns a boolean indicating whether the transition was successful (this won’t work if the window was already in the native fullscreen). This is how fullscreen used to work on macOS in versions before Lion. And allows the user to have a fullscreen window without using another space or taking control over the entire monitor.
On other platforms, this is the same as {@link Window.setFullscreen}.
Parameters
fullscreen
Whether the window should go to simple fullscreen or not.
