HarmonyOS 点击穿透的策略

参考demo：

// xxx.ets
import promptAction from '@ohos.promptAction';

@Component
struct child{
  submitArrow?: () => void
  build() {
    Column(){
    }
    .width('500px')
    .height('500px')
    .backgroundColor(0xAFEEEE)
    .onClick((event: ClickEvent)=>{
      if (event.x<50&&event.y<80) {
        if (this.submitArrow) {
          this.submitArrow()
        }
      }else {
        promptAction.showToast({ message: '子组件响应', duration: 3000 })
      }
    })
  }
}

@Entry
@Component
struct Parent {

  @State text: string = 'Button'
  pButton: () => void = () => {
    promptAction.showToast({ message: '父组件响应', duration: 3000 })
  }
  build() {
    Column() {
      child({ submitArrow: this.pButton })
    }
    .width('100%')
    .height('100%')
    .backgroundColor(0xF1F3F5)
    .justifyContent(FlexAlign.Center)
    .padding({ left: 12, right: 12, bottom: 24 })
  }
}
