Win32，WndProc和父子窗口 [英] Win32 , WndProc, and parent-child windows

问题描述

我正在使用Win32 Api创建多个窗口的C代码进行开发. 我两次使用createWindow-创建父窗口和子窗口. 我有一个消息循环

I'm developing in C code that uses the Win32 Api to create multiple windows. I used createWindow twice - to create parent and child windows. I have a message loop

while ( GetMssage (&msg, NULL,0,0)){
.
translate
dispatch
. 
}

但是我只调用一次WND_Proc函数，而不是每个窗口两次.

But I only get the WND_Proc function called once, instead of twice for each of the windows.

我在做什么错了?

推荐答案

如果我正确理解了您的问题，则您应该希望WndProc会为为其创建的每个窗口类的所创建的每个窗口收到一条WM_CREATE消息. WndProc已注册.

If I'm understanding your question correctly, you should expect your WndProc to receive a single WM_CREATE message for each window created of the window class for which the WndProc is registered.

您的WndProc将不会为您创建的其他类的窗口(例如，像标准Windows UI控件)收到WM_CREATE，即使它是WndProc类别的窗口的直接子代也是如此.如果您向我们提供了有关您要完成的工作的更多详细信息，我们可以提供建议或解决方法.

Your WndProc will not receive a WM_CREATE for a window you create of a different class (like the standard Windows UI controls, for example), even if it is a direct child of a window of the WndProc's class. If you gave us some more specifics on what you are trying to accomplish we could provide suggestions or workarounds.

这个问题也可能会消失更多了解您的情况.
