推荐答案

不！按钮有两种状态:一种显示按钮为默认，另一种状态显示按钮当前是否具有输入焦点.如果它具有输入焦点，则表示如果您单击空白，它将询问为单击".如果是默认设置，即使键盘焦点在其他位置，如果您按Enter键也将执行此操作.

这是您不想删除的非常重要的视觉反馈.

但是，如果您确实想允许这种违反通用UI样式的行为，则可以执行以下操作:1)添加按钮样式BS_OWNERDRAW并根据自己的喜好执行所有者绘制，2)创建一个按钮无法聚焦.

No! There are two states of the button: one shows that the button is default, another state shows if it currently has input focus. If it has input focus, it indicated that it will ask as "click" if you hit blank space. If it is default, it will do it if you hit Enter even if the keyboard focus is somewhere else.

This is very important visual feedback you don''t want to remove.

However, if you really want to allow such violation of the common UI style, you can do the following: 1) Add button style BS_OWNERDRAW and perform owner draw at your liking, 2) make a button non-focusable.

您需要对其进行子类化(单击此处 [ ^ ] Chris Maunder撰写的很棒的子类化文章)

在您的新按钮回调中，处理 WM_SETFOCUS [ ^ ]

You need to subclass it (click here[^] for a great subclassing article by Chris Maunder)

And within your new button callback, process WM_SETFOCUS[^]
