求大佬告知如何获取窗口的宽度

 import window from '@ohos.window'; 
 
//获取窗口对象 
let windowClass = await window.getLastWindow(getContext()); 
//获取窗口属性 
let properties = windowClass.getWindowProperties(); 
//获取窗口宽高 
console.log("width: "+ properties.windowRect.width); 
console.log("height: "+ properties.windowRect.height);
