@Entry 
@Component 
struct TestGesture { 
 build() { 
  Column() { 
   Column() { 
    Text("C") 
     .width("50%") 
     .height("50%") 
     .textAlign(TextAlign.Center) 
     .onClick(() => { 
      console.log("testC Click") 
     }) 
     .onTouch((event)=>{ 
      event.stopPropagation() 
     }) 
     .monopolizeEvents(true) 
     .backgroundColor(Color.Pink) 
   }.width("50%") 
   .height("50%") 
   .onTouch((event) => { 
    console.log("testB Touch") 
    event.stopPropagation() 
   }).backgroundColor(Color.Orange) 
  }.width("100%") 
  .height("100%") 
  .onTouch(() => {
