HarmonyOS pan手势问题

目前只能在回调里判断，因为ontouch拦截影响不到已经发生的回调，参考示例如下：

import { mediaquery } from '@kit.ArkUI';

// xxx.ets
@Entry
@Component
struct PanGestureExample0814 {
  @State offsetX: number = 0
  @State offsetY: number = 0
  @State positionX: number = 0
  @State positionY: number = 0
  private panOption: PanGestureOptions = new PanGestureOptions({ direction: PanDirection.All })
  private listener = mediaquery.matchMediaSync('(orientation: landscape)'); //监听横屏事件
  @State panEnable: boolean = true;

  aboutToAppear(): void {
    this.listener.on('change', (mediaQueryResult: mediaquery.MediaQueryResult) => {
      this.onPortrait(mediaQueryResult)
    });
  }

  aboutToDisappear(): void {
    this.listener.off('change', (mediaQueryResult: mediaquery.MediaQueryResult) => {
      this.onPortrait(mediaQueryResult)
    });
  }

  onPortrait(mediaQueryResult: mediaquery.MediaQueryResult) {
    console.info('mediaQueryResult.matches:' + mediaQueryResult.matches)
    if (mediaQueryResult.matches) {
      console.log('横屏')
      this.panEnable = false;
    } else {
      console.log('竖屏')
      this.panEnable = true;
    }
  }

  build() {
    Column() {
      Column() {
        Column() {
          Text('PanGesture offset:\nX: ' + this.offsetX + '\n' + 'Y: ' + this.offsetY)
        }
        .height(200)
        .width(300)
        .padding(20)
        .border({ width: 3 })
        .translate({ x: this.offsetX, y: this.offsetY, z: 0 }) // 以组件左上角为坐标原点进行移动
        // 左右拖动触发该手势事件
        .gesture(
          PanGesture(this.panOption)
            .onActionStart((event: GestureEvent) => {
              console.info('Pan start')
            })
            .onActionUpdate((event: GestureEvent) => {
              if (!this.panEnable) {
                return;
              }
              if (event) {
                this.offsetX = this.positionX + event.offsetX
                this.offsetY = this.positionY + event.offsetY
              }
            })
            .onActionEnd((event: GestureEvent) => {
              this.positionX = this.offsetX
              this.positionY = this.offsetY
              console.info('Pan end')
            })
        )
      }

      Text('手势：' + this.panEnable)
      Button('屏蔽手势')
        .onClick(() => {
          this.panEnable = false;
        })

      Button('开启手势')
        .onClick(() => {
          this.panEnable = true;
        })
    }.width('100%').height('100%')
  }
}
