HarmonyOS @ohos.ArkUI.advanced.SegmentButton (分段按钮) 如何触发点击事件

可以在@watch监听方法中编写点击事件的逻辑

import {
  ItemRestriction,
  SegmentButton,
  SegmentButtonOptions,
  SegmentButtonTextItem
} from '@ohos.ArkUI.advanced.SegmentButton'

@Entry
@Component
struct Index {
  @State tabOptions: SegmentButtonOptions = SegmentButtonOptions.tab({
    buttons: [{ text: '页签按钮1' }, { text: '页签按钮2' },
      { text: '页签按钮3' }] as ItemRestriction<SegmentButtonTextItem>,
    backgroundBlurStyle: BlurStyle.BACKGROUND_THICK
  })
  @State tf: boolean = true
  @State @Watch('onSegmentButtonChange') tabSelectedIndexes: number[] = [0]

  onSegmentButtonChange() {
    this.tf = !this.tf
    console.log(`选中按钮索引 -- ${this.tabSelectedIndexes}`);
  }

  aboutToAppear(): void {
    console.log("122233")
  }

  build() {
    Row() {
      Column() {
        Column({ space: 25 }) {
          SegmentButton({ options: this.tabOptions, selectedIndexes: $tabSelectedIndexes })
          TextInput({ text: `${this.tabSelectedIndexes}` }).enabled(this.tf)
        }.width('90%')
      }.width('100%')
    }.height('100%')
  }
}
