swing 中一些控件的点击事件 (2)--JComboBox

JComboBox

Integer Month[]= {1,2,3,4,5,6,7,8,9,10,11,12};
JComboBox jComboBox1=new JComboBox(Month);
jComboBox1.addItemListener(new ItemListener()
{
    public void itemStateChanged(ItemEvent event)
    {
        switch (event.getStateChange())
        {
        case ItemEvent.SELECTED: 
            System.out.println("选中" + event.getItem());
            break;
        case ItemEvent.DESELECTED:
            System.out.println("取消选中"+event.getItem());
            break;
        }
    }
});

JComboBox的监听事件，通过 event.getStateChange() 方法来获取是否处于选中某一项的状态，若处于选中状态,则再通过 event。getItem()即可获取选中项。
