java - How can I customize the render of JRadioButton? -

-

i've created jradiobutton subclass in override paintcomponent method so:

@override protected void paintcomponent(graphics g) {     g.drawimage(         isselected() ?             getcheckedimg() :            getbasicimg()     , 0, 0, this); }

but seems once button drawn, that's image uses forever. isselected test doesn't seem have effect. graphics cached or java? how provide custom jradiobutton selected , unselected image? have write custom ui?

read api. there methods like:

seticon() setselectedicon()

among others can use instead of doing custom painting.
