很久没来了，不是一位朋友给我发邮件问我关于swing的问题，才想起，然后翻看了之前的代码，发现当年还实现了一个Vista风格的按钮没有放出来，现在补上，也许现在人们的swing水平对我这代码不屑一顾，不过还是依然抛砖引玉，给未知的人们一个启发。还是老惯例，上效果图：
正常情况下：（和vista一样具有焦点的按钮的颜色渐深渐浅的循环变化）
鼠标在区域内时：
鼠标按下去：
然后是代码：RButtonUI:

使用代码时，只需要在启动时，加入如下代码，然后new JButton()就行了，因为UIManager会在显示时使用RButtonUI来显示。
UIManager.getLookAndFeelDefaults().put(
"
ButtonUI
"
,
"
ruislan.rswing.RButtonUI
"
);
UIManager.getLookAndFeelDefaults().put(
"
Button.font
"
,
new
Font(
"
system
"
, Font.PLAIN,
12
)); |
