在Win32创建自定义消息类型？ [英] Creating custom message types in win32?

问题描述

有没有一种方法来定义和在Win32中发送自定义消息类型，由您的主要消息处理程序被抓？例如，我的主要消息处理程序捕获的信息，如WM_PAINT，WM_RESIZE，WM_LBUTTONDOWN等。我可以创建自己的WM_DOSOMETHING？如果是这样，我怎么会发这个消息？

Is there a way to define and send custom message types in Win32, to be caught by your Main message handler? For example, my main message handler captures messages such as WM_PAINT, WM_RESIZE, WM_LBUTTONDOWN etc. Can I create my own WM_DOSOMETHING? If so, how would I send this message?

嗯，其实我刚发现这是之前<一问href=\"http://stackoverflow.com/questions/293723/how-could-i-create-a-custom-windows-message\">here,但是，它并没有回答我怎么会实际发送此消息。

Ah, I actually just discovered this was asked before here, however, it doesn't answer how I would actually send this message.

推荐答案

是的。只需要声明一个恒定的范围内WM_USER例如

Yes. Just declare a constant in the WM_USER range e.g.

#define WM_RETICULATE_SPLINES (WM_USER + 0x0001)

您也可以通过名称使用RegisterWindowMessage API注册的消息。

You can also register a message by name using the RegisterWindowMessage API.

您可以然后使用SendMessage函数，PostMessage的或任何其变种发送这些消息。

You can then send these messages using SendMessage, PostMessage or any of their variants.
