将ButtonGroup添加到JPanel

Question

JPanel.add(ButtonGroup);

不管用.我必须将它添加到JPanel,因为我正在使用制表符.这真的很令人沮丧.我还没有找到办法

Answer 1

由于ButtonGroup不是组件,因此无法将ButtonGroup添加到JPanel.而是将您的按钮添加到JPanel,例如:

JPanel jPanel = new JPanel();
ButtonGroup group = new ButtonGroup();
btn1 = new JRadioButton("btn1 ");btn1.setSelected(true);
btn2 = new JRadioButton("btn2 ");
group.add(btn1 );
group.add(btn2 );

jPanel.add(btn1);
jPanel.add(btn2).

希望它会有用.

谢谢
