窗口是否在屏幕最前

Question

怎么知道自己的软件是运行在屏幕最前，还是有其它窗口在更前面呢？

Answer 1

怎么定义屏幕最前？比如说窗口是否active，你的软件的窗口框架如果是active的应该就是最前的吧。

GetActiveWindow 这个函数符合你的需求吗。

Answer 2

这不是我需要的函数，因为不管我的窗口在什么情况下，返回的都是本窗口的句柄

Answer 3

你是想让你的软件能够自己监测自己是否激活具有焦点吗，考虑处理WM_ACTIVATE消息。最好描述一下你要的情景的逻辑。

Answer 5

GetForegroundWindow()试试，如果不行的话，您可以试试EnumWindows来枚举窗口，窗口顺序是按照Z-Order来排列的，看看您自己的窗口是否在最前面。

经过测试，GetForegroundWindow()的确可以获取屏幕最前窗口，谢谢^_^
