JAVA JCKECKBOX 事件 g.addItemListener(new JCheckboxListener());

ad5248 2010-04-18 08:49:43
g.addItemListener(new JCheckboxListener());
g_1.addItemListener(new JCheckboxListener());
g_2.addItemListener(new JCheckboxListener());
g_3.addItemListener(new JCheckboxListener());
这样写事件
class JCheckboxListener implements ItemListener {
public void itemStateChanged(ItemEvent e) {
if (g.isSelected()) {/* button事件 */}
if (g_1.isSelected()) { /*button事件 */}
if (g_2.isSelected()) {/*button事件*/ }
if (g_3.isSelected()) {/*button事件*/ }
}
//为什么我只要把他们选中一次 即使下次把选中的取消了 那些button事件还在 很是疑惑 高人回答
