如何用JComboBox禁用和开始jTabbedPane中标签栏

Question

jTabbedPane一个有2个标签栏，jPanel1,jPanel2，当选择JComboBox中num1的时候jPanel1可用，jPanel2标签栏禁用，当选择JComboBox中num2 的时候，jPanel1禁用，jPanel2可用怎么实现啊。我自己只是想到用jComboBoxItemStateChanged事件和setEnabledAt属性，但是总是实现不了，关闭了没法开启。。郁闷啊大家帮帮忙。。

Answer 1

自己解决了private void jComboBox2ActionPerformed(java.awt.event.ActionEvent evt) {                                           
        // TODO add your handling code here:
            // index=jComboBox2.getSelectedIndex();
            String value=(String) jComboBox2.getSelectedItem();            if(value=="num1"){
                jTabbedPane1.setEnabledAt(2,false);
                jTabbedPane1.setEnabledAt(1,true);
            }
            if(value=="num2"){
                jTabbedPane1.setEnabledAt(1,false);
                jTabbedPane1.setEnabledAt(2,true);
            }    }                                                                              

Answer 2

也许这样写的代码更好点 String value=(String) jComboBox2.getSelectedItem();
 if("num1".equals(value)){
    // do something        
 }
