// xxx.ets 
import promptAction from '@ohos.promptAction'; 
 
@Entry 
@Component 
struct Index { 
  build() { 
    Row() { 
      Column() { 
        Widgets({ 
          onClickOK: (): void => { 
            promptAction.showToast({ message: 'test' }); 
          } 
        }) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
} 
 
@Component 
export default struct Widgets { 
  onClickOK?: () => void; 
 
  build() { 
    Row() { 
      Column() { 
        Button('事件') 
          .onClick(() => { 
            if (this.onClickOK !== undefined) { 
              this.onClickOK(); 
            } 
          }) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
