修改JButton的L&F，Java也可以
buttonA.putClientProperty(SubstanceLookAndFeel.BUTTON_SIDE_PROPERTY, SubstanceConstants.Side.LEFT); //这是button里里面的方法，参数很好理解，第一个是隐藏button的边，第二个是隐藏哪一个边。 //如果同时隐藏的边数超过1的话，就需要用到容器EnumSet。 // 自然就是把第二个参数改为EnumSet类型。 //EnumSet自然就是存放所有的要隐藏或者是修改的边。EnumSet<Side> leftTopSides = EnumSet.of(SubstanceConstants.Side.LEFT, SubstanceConstants.Side.TOP); buttonC.putClientProperty(SubstanceLookAndFeel.BUTTON_SIDE_PROPERTY, leftTopSides); buttonC.putClientProperty( SubstanceLookAndFeel.BUTTON_OPEN_SIDE_PROPERTY, leftTopSides);
buttonA.putClientProperty( SubstanceLookAndFeel.BUTTON_OPEN_SIDE_PROPERTY, SubstanceConstants.Side.LEFT);//这段代码是将边修改为直线型的

?
最后一点实现这个必须引入第三方包，不过这个包网上下载的很多是错的。很让人恼火，不过幸好找到一个差不多的，让我我就放到附件里面，有需要的话，各位可以下载。
