Swing之ButtonGroup用法实例

1 就是起作用范围的，不是组件，不能被容器添加，目的让其中一个起作用，例如radiobutton

package com.szsm.swing.framepanel;import java.awt.FlowLayout;import javax.swing.ButtonGroup;import javax.swing.JRadioButton;import com.szsm.swing.parent.FrameSet;/** * ButtonGroup用法 * @author chaigw * */public class BtnGroupFrame extends FrameSet{@Overrideprotected void initInterface() {super.initInterface();ButtonGroup group = new ButtonGroup();JRadioButton r = new JRadioButton("r");JRadioButton r2 = new JRadioButton("r");group.add(r);group.add(r2);//parentContainer.setLayout(new FlowLayout());this.setLayout(new FlowLayout());parentContainer.add(r);parentContainer.add(r2);}public static void main(String[] args) {new BtnGroupFrame();}}
