子窗口getPreferredOrientation获取到的是横向设置没问题，但是ui显示还是纵向的

直接设置主窗口的方向即可。参考demo：

import window from '@ohos.window';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Text('反向横屏')
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(async ()=>{

            try {
              const topWindow = await window.getLastWindow(getContext(this));
              console.info('Succeeded in obtaining the top window. Data: ' + JSON.stringify(topWindow));
              await topWindow.setPreferredOrientation(window.Orientation.LANDSCAPE_INVERTED);
              console.info('Succeeded in setting window orientation.');
            } catch (error) {
              console.error('Failed to obtain or set the top window. Cause: ' + JSON.stringify(error));
            }
            /*window.getLastWindow(getContext(this),(err,win)=>{
              win.setPreferredOrientation(window.Orientation.LANDSCAPE_INVERTED)
            })*/
          })

        Text("竖屏")
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(async ()=>{
            try {
              const topWindow = await window.getLastWindow(getContext(this));
              console.info('Succeeded in obtaining the top window. Data: ' + JSON.stringify(topWindow));
              await topWindow.setPreferredOrientation(window.Orientation.PORTRAIT);
              console.info('Succeeded in setting window orientation.');
            } catch (error) {
              console.error('Failed to obtain or set the top window. Cause: ' + JSON.stringify(error));
            }
            /*window.getLastWindow(getContext(this),(err,win)=>{
              win.setPreferredOrientation(window.Orientation.PORTRAIT)
            })*/
          })

      }
      .width('100%')
    }
    .height('100%')
  }
}
