 公共类OptionFrame扩展的JFrame {     公共OptionFrame（）{
            UIManager.put（RadioButton.focus，新的将ColorUIResource（Color.GREEN））;

我无法理解为什么上面code是行不通的。

由于这里讨论，外观是由外观和放大器控制;感觉依赖UI委托。委托是免费的呈现点但是它为所欲为;有些忽略默认和委托到主机平台组件。短写你自己的 ButtonUI ，替换图标是退而求其次的。这例如说明了 JToggleButton中的选中状态的效果， 一个JRadioButton父。 Col​​orIcon ，看到这里，也是方便在这一背景下，更多的例子被认为 href=\"http://stackoverflow.com/q/6774987/230513\">。

When any Radio Button in my Java UI program is selected, the selection is shown by a black dot. I want to make it Green. I'm using Java Swing. I followed the answer given to this SO Question , but it's not working for me. It still shows a black dot when selected.

public class OptionFrame extends JFrame {

     public OptionFrame(){
            UIManager.put("RadioButton.focus", new ColorUIResource(Color.GREEN));
            SwingUtilities.updateComponentTreeUI(this);
     }
}

I'm unable to understand why above code is not working. Any suggestions are highly appreciated.

Thanks.

As discussed here, the appearance is controlled by the Look & Feel dependent UI delegate. The delegate is free to render the dot however it pleases; some ignore the defaults and delegate to a host platform component. Short of writing your own ButtonUI, replacing the Icon is the next best thing. This example illustrates the effect for the selected state of JToggleButton, the parent of JRadioButton. ColorIcon, seen here, is also handy in this context, and more examples are seen here.
