编辑控件不会生成WM_COMMAND消息 [英] Edit control doesn't generate WM_COMMAND messages

问题描述

我有一个编辑控件.在父窗口中，我正在监听WM_COMMAND消息.但是我的控件不会在更改时发送它.此外，当我使用Spy观看消息时，在编辑控件本身上只能看到不同的键盘消息，而在主父窗口中唯一的消息是WM_CTLCOLOREDIT.

I have an edit control. In the parent window I'm listening a WM_COMMAND message. But my control doesn't send it on change. Moreover, when I'm watching messages with Spy I can see only different keyboard messages on the edit control itself and the only message in the main parent window is WM_CTLCOLOREDIT.

P.S .:我正在做的唯一一件有趣的事情-我正在创建HWND_MESSAGE父级的编辑，稍后再使用SetParent();

P.S.: The only interesting thing I'm doing - I'm creating an edit with HWND_MESSAGE parent and assign a parent later with SetParent();

推荐答案

对于编辑控件，通知将发送到该控件的原始父级.也就是说，在您的情况下，仅消息窗口.

For an edit control, notifications are sent to the original parent of the control. That is, in your case, the message only window.

在对

In a comment to a similar question Raymond Chen says:

许多控件缓存原始父级.您对此无能为力.

Many controls cache the original parent. Not much you can do about it.

您最好将编辑控件的创建推迟到创建其父控件之前.

You may be best postponing creation of the edit control until you have created its parent.
