在现代版本的 Windows 上最小化窗口是否仍将其移动到坐标 (-32000, -32000)？

Question

根据Raymond Chen 的这篇博客文章，Windows NT 通过将窗口移动到坐标 (-32000, -32000) 来“最小化”窗口，并且，我从阅读它得到的印象是 Windows NT的早期版本就是这种情况（3.x，4...）。

在现代版本的 Windows NT（例如 7、8 和 10）中，情况是否仍然如此？

是否有可以编写的程序来演示现代 Windows 操作系统上此功能的存在/不存在？

Answer 1

回答我自己的问题...我编写了一个小型 C 程序来完成我的要求。基本上，它使用代码创建一个窗口，如果窗口的位置在 x 或 y 维度上更改为负值，它会将静态文本字段的文本设置为新坐标。

该程序在 Windows 10 RTM 上的输出：

#include <Windows.h>
#include <windowsx.h>

运行时，如果最小化然后重新最大化，它会显示（-32000，-32000），表明这是窗口最小化时移动到的位置。
