用swing怎么实现相互移动两个list框里的数据？

[Wallance_1979]

我现在要实现的一个功能是用swing实现移动两个list框里面的数据，比如选定A框里的一个item，把它移动到B框里或相反。要实现这个功能用什么对象比较好？JList，JComboBox，还是？？

[shmilycharlene]

使用两个JList来实现,

写一个ListModel出来,可以继承AbstractListModel类,然后重写其中的方法,这样完全可以实现,注意在JList上添加鼠标事件

[yyc6219869]

使用JList,加几个按钮，实现点击事件。

[leeson11111]

现个JList，加几个按钮。一个add一个remove。

[wunan320]

JList,JComboBox都可以，看界面需要什么控件了。
A、B两个控件。
可以通过按钮的事件，把A选择的item，从A中删除，在B中增加。
也可以用drag，同上。

用 jlist。然后就可以了。然后结合vector类

楼上的几位都可以实现 ,好方法
