HarmonyOS 禁止登录页面截屏：window.findWindow\("test"\)问题？

Question

示例代码：

let isPrivacyMode: boolean = true;
let windowClass: window.Window = window.findWindow("test");
let promise = windowClass.setWindowPrivacyMode(isPrivacyMode); // 设置防截屏录屏
promise.then(() => {
  console.info('Succeeded in setting the window to privacy mode.');
}).catch((err: BusinessError) => {
  console.error(`ErrorCode: ${err.code},  Message: ${err.message}`);
})

问题：

let windowClass: window.Window = window.findWindow("test");

这行代码报错，应该是找不到 'test'的window，需要在哪里设置什么吗

Answer 1

执行window.findWindow：查找name所对应的窗口之前，先要创建name为”test“窗口，要先确认是否创建成功了名称为test的窗口。创建子窗口或者系统窗口, 参考链接：
