查找哪个 MFC 子窗口将接收鼠标单击
所以，我有一个 MFC 程序的插件。我正在使用鼠标事件挂钩（来自 SetWindowsHookEx）来捕获点击。主机应用程序可以打开任意数量（可能重叠）的子窗口，但我只想拦截特定子窗口中的点击。
有没有办法在钩子过程中找出哪个子窗口将处理点击？我想这就像枚举所有子窗口，查看 Z 顺序，但我对 MFC/Win32 库非常不熟悉，而且我找不到任何关于如何枚举所有子窗口并计算哪个是好的讨论最上面。
So, I have a plugin to an MFC program. I'm using a mouse event hook (from SetWindowsHookEx) to capture clicks. The host application can have any number of (possibly overlapping) child windows open, but I only want to intercept clicks in a particular child window.
Is there a way to figure out in the hook proc which of the child windows would process the click? I guess it's something like enumerate all child windows, looking at Z-order, but I'm very unfamiliar with the MFC/Win32 libraries, and I'm not able to find any good discussion about how to enumerate all children and calculate which is topmost.

也许
WindowFromPointAPI 函数符合要求吗？该文档没有明确提及 Z 排序，但我可以根据第一手经验向您保证，“包含”隐含意味着前面没有其他窗口。
还有其他几个，其行为略有不同：
ChildWindowFromPoint，ChildWindowFromPointEx和RealChildWindowFromPoint。Maybe the
WindowFromPointAPI function fits the bill?The documentation does not explicitly mention Z ordering, but I can assure you from first-hand experience that "contains" implicitly means that no other window is in front.
There are several more of these, with slightly different behaviour:
ChildWindowFromPoint,ChildWindowFromPointExandRealChildWindowFromPoint.自从我做 MFC 以来已经很长时间了，但我认为 HitTest 就是您正在寻找的术语。快速浏览 MSDN 表明大多数窗口都实现了 HitTest 函数，该函数返回有关特定点的信息。
It's been a long time since I did MFC, but I think that HitTest is the term you're looking for. A quick trawl through MSDN indicates that most windows implement a HitTest function that returns information about a particular point.
