修改Button的边框

longyi_java

在TinyLookAndFeel.java 的 protected void initComponentDefaults(UIDefaults table)  方法中设置
 
table.put("Button.border",   new BorderUIResource.CompoundBorderUIResource(    new TinyButtonBorder(),    new BasicBorders.MarginBorder())); 
 
 
TinyButtonBorder是继承AbstractBorder.java和实现UIResource.java 的类
