RemoteWindow

远程控制窗口组件，可以通过此组件控制应用窗口，提供启动退出过程中控件动画和应用窗口联动动画的能力。

说明：

该组件从API Version 9开始支持。后续版本如有新增内容，则采用上角标单独标记该内容的起始版本。

该组件为系统接口。

子组件

不可以包含子组件。

接口

RemoteWindow(target: WindowAnimationTarget)

通过窗口动画对象创建组件。

参数:

参数名	参数类型	必填	参数描述
target	WindowAnimationTarget	是	需要控制的动画窗口的描述。

WindowAnimationTarget

目标窗口，用来远程控制实现动画。

参数	类型	描述
bundleName	string	动画窗口所对应的进程。
abilityName	string	动画窗口所对应的Ability。
windowBounds	RRect	动画窗口实际大小。
missionId	number	任务ID。

RRect

圆角矩形。

参数	类型	描述
left	number	动画窗口左上角相对于屏幕横坐标。
top	number	动画窗口左上角相对于屏幕纵坐标。
width	number	动画窗口宽度大小。
height	number	动画窗口高度大小。
radius	number	动画窗口圆角大小。

属性

支持通用属性。

事件

支持通用事件。

示例

RemoteWindow需要接收由windowAnimationManager设置的WindowAnimationController对象传入对应窗口WindowAnimationTarget对象，可以创建一个RemoteWindowExample.ets作为示例组件将RemoteWindow组件和传入的WindowAnimationTarget对象关联封装起来。由于RemoteWindow只能用于系统应用程序Launcher中，可以将RemoteWindowExample组件放置于Launcher的EntryView.ets页面的build函数中，编译Launcher, 然后推送Launcher安装包到设备系统中运行。

// WindowAnimationControllerImpl.ets 文件
import windowAnimationManager from '@ohos.animation.windowAnimationManager';

export default class WindowAnimationControllerImpl implements windowAnimationManager.WindowAnimationController {
  onStartAppFromLauncher(startingWindowTarget: windowAnimationManager.WindowAnimationTarget,
                         finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void
  {
    console.log(`remote window animaion onStartAppFromLauncher`);
    finishedCallback.onAnimationFinish();
  }

  onStartAppFromRecent(startingWindowTarget: windowAnimationManager.WindowAnimationTarget,
                       finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void {
    console.log(`remote window animaion onStartAppFromRecent`);
    finishedCallback.onAnimationFinish();
  }

  onStartAppFromOther(startingWindowTarget: windowAnimationManager.WindowAnimationTarget,
                      finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void {
    console.log(`remote window animaion onStartAppFromOther`);
    finishedCallback.onAnimationFinish();
  }

  onAppTransition(fromWindowTarget: windowAnimationManager.WindowAnimationTarget,
                  toWindowTarget: windowAnimationManager.WindowAnimationTarget,
                  finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void{
    console.log(`remote window animaion onAppTransition`);
    finishedCallback.onAnimationFinish();
  }

  onMinimizeWindow(minimizingWindowTarget: windowAnimationManager.WindowAnimationTarget,
                   finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void {
    console.log(`remote window animaion onMinimizeWindow`);
    finishedCallback.onAnimationFinish();
  }

  onCloseWindow(closingWindowTarget: windowAnimationManager.WindowAnimationTarget,
                finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void {
    console.log(`remote window animaion onCloseWindow`);
    finishedCallback.onAnimationFinish();
  }

  onScreenUnlock(finishedCallback: windowAnimationManager.WindowAnimationFinishedCallback): void {
    console.log(`remote window animaion onScreenUnlock`);
    finishedCallback.onAnimationFinish();
  }

  onWindowAnimationTargetsUpdate(fullScreenWindowTarget: windowAnimationManager.WindowAnimationTarget, 
                              floatingWindowTargets: Array<windowAnimationManager.WindowAnimationTarget>): void {
