Navigation拉起浮窗，怎样使用Navigation拉起一个Panel实现的浮窗效果

import router from '@ohos.router' 
 
@Entry 
@Component 
struct PanelExample { 
  @State show: boolean = false 
  onPageShow() { 
    this.show = !this.show 
  } 
 
  build() { 
    Column() { 
 
      Panel(this.show) { // 展示日程 
        Column() { 
          Text('Today Calendar') 
          Divider() 
          Text('1. afternoon 4:00 The project meeting') 
        } 
      } 
      .type(PanelType.Foldable) 
      .mode(PanelMode.Half) 
      .dragBar(true) // 默认开启 
      .halfHeight(700) // 默认一半 
      // .showCloseIcon(true) // 显示关闭图标 
      .onChange((width: number, height: number, mode: PanelMode) => { 
        console.info(`width:${width},height:${height},mode:${mode}`) 
        if (mode == 0) { 
          this.show = !this.show 
          router.back() 
        } 
      }) 
 
      if (this.show == false) { 
        Blank().color(Color.Black).width(20).height(20) 
          .onClick(() => { 
            this.show = !this.show 
          }) 
      } 
 
 
    }.width('100%') 
    .height('100%') 
    .backgroundColor('#cccccccc') 
    .padding({ top: 5 }) 
  }
