@Entry 
@Component 
struct OnTouchDemo { 
  build() { 
    // outer stack 
    Stack() { 
      Button('outer button') 
        .margin({left : 200}) 
        .onTouch((event) => { 
          console.info('outer button touched type: ' + (event as TouchEvent).type) 
        }) 
      // inner stack 
      Stack() { 
        Button('inner button') 
          .onTouch((event) => { 
            console.info('inner button touched type: ' + (event as TouchEvent).type) 
          }) 
      } 
      .width("100%").height("100%") 
      .hitTestBehavior(HitTestMode.None) 
      .onTouch((event) => { 
        console.info('stack touched type: ' + (event as TouchEvent).type) 
      }) 
 
      Text('Transparent') 
        .hitTestBehavior(HitTestMode.Transparent) 
        .width("100%").height("100%") 
        .onTouch((event) => { 
          console.info('text touched type: ' + (event as TouchEvent).type) 
        }) 
    }.width(300).height(300) 
  }
