如何获取Text组件中文字的宽度
================

使用@ohos.measure中的measureText()方法计算指定文本单行布局下的宽度。具体可参考如下代码：

@Entry
@Component
struct IndexTest {
  @State textWidth: number = this.getUIContext().getMeasureUtils().measureText({
    textContent: "Hello World",
    fontSize: '50px'
  })

  build() {
    Row() {
      Column() {
        Text(\`The width of 'Hello World': ${this.textWidth}\`)
      }
      .width('100%')
    }
    .height('100%')
  }
}
