推荐答案

您必须自己绘制这些控件.通常的方法是创建一个从CButton(或CCheckbox)派生的新类，并覆盖OnPaint命令.不要忘记，您还必须为控件可以具有的所有状态绘制.

那里可能已经有代码可以编辑您想要的东西了(很可能就在CodeProject上). Google是您的朋友.

You have to paint those kinds of controls yourself. The usual way to do this is to create a new class derived from CButton (or CCheckbox), and override the OnPaint command. Don''t forget that you have to also paint for ALL states the control can have.

There''s probably already code out there to do edxactly what you want (and most likely right here on CodeProject). Google is your friend.
