# 在可扩展的窗口中监控 Windows

您可以将 Windows 设置为在可调整至任意大小的窗口中显示，在此窗口中内容可根据窗口大小进行缩放。我们将此称为**画中画**模式。如果您想在运行 macOS 的同时监视 Windows 中运行的应用程序和其他任务，则会发现此模式十分有用。

要切换至“画中画”模式，请执行以下操作：

* 在窗口模式下，选择**查看** > **进入画中画**。

欲了解更多有关画中画模式的信息，请参阅[画中画模式设置主题](/pdfm-19-ug-zh_cn/parallels-desktop-for-mac-19-users-guide/gao-ji-zhu-ti/hua-zhong-hua-mo-shi.md)。
