将一个窗口镜像到另一个 [英] Mirroring one window to another

问题描述

我有一个 MFC 窗口对象，其中包含有关它的所有信息.我正在寻找一种将其镜像到另一个窗口的方法，以便两个窗口看起来相同.我听说可以通过 DWM 窗口预览来实现.

I have an MFC window object with all the information about it. I'm looking for a way to mirror it to another window so that both windows look identical. I've heard it's possible through DWM window previewing.

怎么做?

推荐答案

解决方案是我对源窗口使用 DWM 缩略图:

The solution was that I used DWM thumbnailing for the source window:

hr = DwmRegisterThumbnail();
hr = DwmUpdateThumbnailProperties();

正如@raymond-chen 建议的那样.

as @raymond-chen suggested.
