请问jlist怎样实现鼠标双击事件打开一个对话框

[Jimreader]

可以模拟来做
设定一个整数
然后在单击的时候给他加一
然后判断大于二时就执行你所需要的代码

不是吧，这样也行

addListSelectionListener
public void addListSelectionListener(ListSelectionListener listener)
Adds a listener to the list that's notified each time a change to the selection occurs. Listeners added directly to the JList will have their ListSelectionEvent.getSource() == this JList (instead of the ListSelectionModel).

Parameters:
listener - the ListSelectionListener to add

import java.awt.event.*;
还要加上这么一个包

[jinannanhai79]

import javax.swing.event.ListSelectionEvent;
import javax.swing.JList;


JList jList1 = new JList();

class SymMouse extends java.awt.event.MouseAdapter
{
public void mouseClicked(java.awt.event.MouseEvent e)
{
Object object = e.getSource();
if(object==jList1)
jList1_mouseClicked(e);
}
}

void jList1_mouseClicked(java.awt.event.MouseEvent event)
{
if(event.getModifiers()==MouseEvent.BUTTON1_MASK&&event.getClickCount()==2)
{
JOptionPane.showMessageDialog(this,"正在测试","警告",JOptionPane.WARNING_MESSAGE);

}
}
SymMouse picker = new SymMouse()
jList1.addMouseListener(picker);
