Panel 组件的遮罩区域能否配置为不生效？

@Entry 
@Component 
struct PanelExample { 
  @State show: boolean = false 
  @State message : string = "Hello World" 
  @State i : number = 0; 
  build() { 
    Column() { 
      Text(this.message) 
        .width('90%') 
        .height(50) 
        .borderRadius(10) 
        .backgroundColor(0xFFFFFF) 
        .padding({ left: 20 }) 
        .onClick(() => { 
          this.show = !this.show 
        }) 
      Button("TEST+1") 
        .onClick(()=>{ 
          this.i++; 
          this.message = "Hello World chick number:" + this.i 
        }) 
      Panel(this.show) { // 展示日程 
        Column() { 
          Text('Today Calendar') 
          Divider() 
          Text('1. afternoon 4:00 The project meeting') 
        } 
      } 
      .type(PanelType.Minibar) 
      .mode(PanelMode.Half) 
      .dragBar(true) // 默认开启 
      .halfHeight(500) // 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}`) 
      }) 
    }.width('100%').height('100%').backgroundColor(0xDCDCDC).padding({ top: 5 }) 
  } 
}
