import window from '@ohos.window'

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

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        Button('横屏').onClick((event: ClickEvent) => {
          window.getLastWindow(getContext(this)).then(windowClass=>{
            let orientation = window.Orientation.LANDSCAPE;
            windowClass.setPreferredOrientation(orientation);
            windowClass.enableLandscapeMultiWindow
          })
        })
      }
      .width('100%')
    }
    .height('100%')
  }
}
