JToolBar toolBar = new JToolBar();
toolBar.setLayout(new FlowLayout(FlowLayout.LEFT));
// toolBar.setLayout(new FlowLayout(FlowLayout.LEFT, 2, 0));

问题是这样的:
radioButton.setText("<html><img src=a image file name>");
可以保留原来的圆形按钮,并将我们的图标放到后面,但是问题是:
我们的这个图标将尽可能地占据剩余空间.如果将这个按钮与其他普通按钮
加到一个工具栏中,我们再最大化窗口,就会发现这个按钮占据了庞大的空间
宽度!!!!!!这是为什么呢?这个按钮变得象glue一样!!!

输入法好了,我重新说一下:

按照liad,可以放置两个图标,一个是原来的,用来指示选择状态;
一个是我们配置的,用来显示按钮含义;但是我们定义的图标将占据
很宽的空间,不管怎样设置大小,都无法避免.

按照后面两者的说法,只能放一个图标.

according to liad, the icon we add will hold a very wide space
even if setting a width property for img,td,or tr html tag.
Also, I use img tag directly,but the same result.....

for YuLimin(阿敏当兵) :
the method tells us how to change icon ,not to set a new icon
together with default round icon.
