如何在 Windows 中获取 z 顺序? [英] How to get the z-order in windows?

问题描述

我正在制作一个应用程序，我可以在其中与每个正在运行的应用程序进行交互.现在，我需要一种获取窗口 z 顺序的方法.例如，如果 Firefox 和记事本正在运行，我需要知道哪个在前面.

I'm making an application where I interact with each running application. Right now, I need a way of getting the window's z-order. For instance, if Firefox and notepad are running, I need to know which one is in front.

有什么想法吗?除了为每个应用程序的主窗口执行此操作外，我还需要为其子窗口和姐妹窗口(属于同一进程的窗口)执行此操作.

Any ideas? Besides doing this for each application's main window I also need to do it for its child and sister windows (windows belonging to the same process).

推荐答案

您可以使用 GetTopWindow 函数搜索父窗口的所有子窗口，并返回 z 顺序最高的子窗口的句柄.GetNextWindow 函数按 z 顺序检索下一个或上一个窗口的句柄.

You can use the GetTopWindow function to search all child windows of a parent window and return a handle to the child window that is highest in z-order. The GetNextWindow function retrieves a handle to the next or previous window in z-order.
