How do you create a custom themed NSButton? I don't mean in a small way like changing the background color or changing from rounded edges to square edges. I want to replace the entire look and feel of the button. Is that even possible to do in Cocoa? Obviously I would have to subclass the NSButton class and go from there. Any help would be much appreciated.

推荐答案

实际上，你需要子类 NSButtonCell 。您应该阅读 Apple的文档，以更好地了解它们如何交互。您可能仍然希望子类 NSButton ，以便它也将使用您的 NSButtonCell 子类。

Actually, you need to subclass NSButtonCell. You should read Apple's documentation on this to gain a better understanding of how they interact. You probably will still want to subclass NSButton so that it will use your NSButtonCell subclass, too.

对于一个按钮，大部分工作是在 drawBezelWithFrame：inView：中完成的。如果你想改变文本或图像的绘制方式，你会覆盖 drawText：withFrame：inView：和 drawImage：withFrame：inView： / code>。

For a button, most of the work is done in drawBezelWithFrame:inView:. If you want to alter the way the text or image is drawn, you would override drawText:withFrame:inView: and drawImage:withFrame:inView:.
