推荐答案

警告有人建议，可以通过调用的setparent并设置窗口为桌面的孩子做到这一点。如果你这样做，可以使Win32的窗口管理器到桌面的输入队列相结合，你的子窗口，这是一个的坏事的 - 的雷蒙德陈解释了原因。

Warning It was suggested that you can accomplish this by calling SetParent and setting the window to be a child of the Desktop. If you do this, you cause the Win32 Window Manager to combine the input queue of the Desktop to your child window, this is a bad thing - Raymond Chen explains why.

另外，请记住，调用SetWindowPos与HWND_BOTTOM是不完整的。你需要做这个，只要您的窗口正在改变ZORDER。处理WM_WINDOWPOSCHANGING事件，看看SWP_NOZORDER获取更多信息。

Also, keep in mind that calling SetWindowPos with HWND_BOTTOM is incomplete. You need to do this whenever your window is changing zorder. Handle the WM_WINDOWPOSCHANGING event, look at SWP_NOZORDER for more info.
