Slider拦截点击事件失败

在Slider拦截Gesture失败, hitTestBehavior为Default,这个不能修改.想问下不是通过onGestureJudgeBegin拦截触摸事件吗?

Slider({  
  value: this.outSetValueOne,  
  min: 0,  
  max: 100,  
  style: SliderStyle.OutSet,  
})  
  .trackColor($r('app.color.color_66FFFFFF'))  
  .selectedColor($r('app.color.color_FF3741'))  
  .blockStyle({  
    type: SliderBlockType.IMAGE,  
    image: $r('app.media.thumb')  
  })  
  .blockSize({  
    width: 10,  
    height: 12,  
  })  
  .trackThickness(2)  
  .onChange((value: number, mode: SliderChangeMode) => {  
    this.outSetValueOne = value  
  })  
  .margin({ left: 8, right: 8})  
  .height(20)  
  .onGestureJudgeBegin((gestureInfo: GestureInfo, event: BaseGestureEvent) => {  
    return GestureJudgeResult.REJECT  
  })

HitTestMode中None 自身不响应触摸测试，不会阻塞子节点和兄弟节点的触摸测试。可以实现拦截触摸事件。

Row() {  
  Slider({  
    value: 50,  
    min: 0,  
    max: 100,  
    style: SliderStyle.OutSet,  
  }).trackColor(Color.Red)  
    .selectedColor(Color.Black)  
    .blockStyle({  
      type: SliderBlockType.IMAGE,  
      image: $r('app.media.app_icon')  
    }).blockSize({  
    width: 10,  
    height: 12,  
  }).trackThickness(2)  
    .onChange((value: number, mode: SliderChangeMode) => {  
    }).margin({ left: 8, right: 8})  
    .height(20)  
    .onGestureJudgeBegin((gestureInfo: GestureInfo, event: BaseGestureEvent) => {  
      return GestureJudgeResult.REJECT  
    }).hitTestBehavior(HitTestMode.None)
