HarmonyOS 怎么获取某一个视图的起始位置？

import componentUtils from '@ohos.arkui.componentUtils';  
@Entry  
@Component  
struct Page1 {  
  build() {  
    Row() {  
      Column() {  
        Text('Hello World')  
          .fontSize(50)  
          .fontWeight(FontWeight.Bold)  
          .id('myText')  
          .backgroundColor(Color.Yellow)  
          .onClick(()=>{  
            let modePosition: componentUtils.ComponentInfo = componentUtils.getRectangleById("myText");  
            console.log('modePosition' + JSON.stringify(modePosition));  
          })  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}

modePosition{"size":{"width":910,"height":197},"localOffset":{"x":175,"y":0},"windowOffset":{"x":175,"y":1279},"screenOffset":{"x":175,"y":1279},"translate":{"x":0,"y":0,"z":0},"scale":{"x":1,"y":1,"z":1,"centerX":14000,"centerY":3030.769230769231},"rotate":{"x":0,"y":0,"z":0,"angle":0,"centerX":14000,"centerY":3030.769230769231},"transform":[1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1]}
