import javax.swing.JPanel;
import javax.swing.JTabbedPane;public class T {
public static void main(String[] args) {
final JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
if (e.getClickCount() == 2 && e.getButton() == MouseEvent.BUTTON1) {
int tabIndex = tabbedPane.indexAtLocation(e.getX(), e.getY());
if (tabIndex != -1) {
tabbedPane.remove(tabIndex);
}
}
}
});
tabbedPane.addTab("Tab1", new JPanel());
tabbedPane.addTab("Tab2", new JPanel());
tabbedPane.addTab("Tab3", new JPanel());
tabbedPane.addTab("Tab4", new JPanel());
tabbedPane.addTab("Tab5", new JPanel()); JFrame f = new JFrame();
f.getContentPane().add(tabbedPane, BorderLayout.CENTER);
f.setSize(300, 200);
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
}
}

mouseClicked()方法不行吗??为什么是mousePressed()呢?WHY?

Answer 3

class CommonFrame extends JFrame
{
JTabbedPane tabPnl;
    Container container;
    JToolBar toolBar;
    JMenuBar menuBar;
    
public CommonFrame()
{
super();
Dimension screanSize = Toolkit.getDefaultToolkit().getScreenSize();
        setSize(680,500);
        Dimension frameSize = this.getSize();
setLocation((screanSize.width-frameSize.width)/2,
                 (screanSize.height-frameSize.height)/2);
container = getContentPane();
container.setLayout(new BorderLayout(5,5));
        setJMenuBar(makeMenuBar());    
        tabPnl = new JTabbedPane(JTabbedPane.TOP,JTabbedPane.SCROLL_TAB_LAYOUT);
        tabPnl.addMouseListener(new MouseAdapter(){
         public void mousePressed(MouseEvent e)
         {
         if (e.getClickCount() == 2 && e.getButton() == MouseEvent.BUTTON1)
         {
         int tabIndex = tabPnl.indexAtLocation(e.getX(),e.getY());
         if (tabIndex != -1)
         tabPnl.remove(tabIndex);
         }
         }
        });
        
        tabPnl.addTab("tab1",new JPanel());
        tabPnl.addTab("tab2",new JPanel());
        tabPnl.addTab("tab3",new JPanel());
        tabPnl.setBackground(Color.GRAY);
        container.add(makeToolBar(),BorderLayout.NORTH);
        container.add(tabPnl,BorderLayout.CENTER);

}
为什么我的代码不行?
