使用dialog窗口实现红包雨窗口创建

import window from '@ohos.window' 
// ArkUI提供的自定义弹窗 
@CustomDialog 
struct CustomDialogExample { 
  controller: CustomDialogController = new CustomDialogController({  
    builder: CustomDialogExample({}), 
  }) 
   
  build() { 
    Column() { 
      Text('我是内容') 
        .fontSize(20) 
        .margin({ top: 10, bottom: 10 }) 
    } 
  } 
} 
@Entry 
@Component 
struct Page1 { 
  dialogController: CustomDialogController = new CustomDialogController({ 
        builder: CustomDialogExample(), 
  }) 
  @State message: string = 'Hello World' 
  onPageShow() { 
    //定时器。5秒后自动创建一个dialog窗口 
    setTimeout(() => { 
      let dialogConfig: window.Configuration = { 
        name: 'moneyRain', 
        ctx: getContext(this), 
        windowType: window.WindowType.TYPE_DIALOG 
      } 
      window.createWindow(dialogConfig, (err, win) => { 
        win.setWindowTouchable(true); 
        win.resize(800, 2600); 
        win.moveWindowTo(50, 800) 
        win.setUIContent('pages/Page2'); 
        win.showWindow(); 
      }) 
    }, 5000) 
  } 
  build() { 
    Row() { 
      Column() { 
        // 按钮触发自定义弹窗 
        Button('click me') 
          .onClick(() => { 
            this.dialogController.open() 
          }) 
      }.width('100%').margin({ top: 5 }) 
    } 
    .width('100%') 
  } 
}
