推荐答案

请看我的评论问题。第二，我发现CodeProject文章解决了这个问题：画你的自己的标签 - 第二版 [ ^ ]。



对于某些圆形（非矩形）控件，这很容易。您需要做的就是提供适当的渲染，最重要的是，将属性 Control.Region 设置为合适的 System.Drawing.Region 表示非矩形形状的对象：

https://msdn.microsoft.com/en-us/library/system.windows.forms.control.region（v = vs.110）的.aspx [< a href =https://msdn.microsoft.com/en-us/library/system.windows.forms.control.region(v=vs.110).aspx\"target =_ blanktitle =New Window > ^ ]，

https://msdn.microsoft.com/en-us/library/system.drawing.region(v = vs.110）.aspx [ ^ ]。



这为您提供了完整的解决方案。

Please see my comment to the question. On second though, I've found CodeProject article where this problem is solved: Painting Your Own Tabs - Second Edition[^].

As to some rounded (non-rectangle) control, this is easy. All you need to do is to provide appropriate rendering and, most importantly, set the property Control.Region to suitable System.Drawing.Region object representing non-rectangular shape:
https://msdn.microsoft.com/en-us/library/system.windows.forms.control.region(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.drawing.region(v=vs.110).aspx[^].

This gives you a complete solution.
