我正在使用SystemLookAndFeel,它在我的按钮周围设置了默认边框。
现在我想要一个黑色边框,但是当我设置边框时,它只是将我的新边框添加到默认边框周围,所以我有两个。
如何在不删除LookAndFeel的情况下更改或删除边框?
另外:我正在使用java 7和Win 8.1
答案 0 :(得分:4)
在Windows 10上使用Java 8,我做了一点测试
正如您所看到的,关于我可以开展工作的唯一方法是使用setContentAreaFilled
一般问题是,许多外观并没有使用border
属性,而是独立绘制自己的边框(因此setBorderPainted
的原因),但外观和感觉对于Windows 10,只是想要与众不同
