this.subWindowClass.setUIContent("…/mainpage/CMOSDigitalPage", (err) => { 
  if (err.code) { 
    LogUtils.error(Failed to load the content. Code:${err.code}, message:${err.message}); 
    return; 
  } 
  if (this.subWindowClass === undefined) { 
    LogUtils.error(‘subWindowClass is undefined.’); 
    return; 
  }
