因为昨天上不了网，翻了好久的API还是翻不出来。。
JPopupMenu这东西要怎么用？我加到一个JFrame里面，右键都点烂，就是不出来。。郁闷。。
有没有简单点的例子给晚辈看看。。
谢谢高手帮忙。。

- Java code
import java.awt.Component;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;import javax.swing.JCheckBoxMenuItem;import javax.swing.JFrame;import javax.swing.JMenu;import javax.swing.JMenuItem;import javax.swing.JPopupMenu;import javax.swing.JRadioButtonMenuItem;public class JPopupMenuTest { private JFrame frame; /** * Launch the application * @param args */ public static void main(String args[]) { try { JPopupMenuTest window = new JPopupMenuTest(); window.frame.setVisible(true); } catch (Exception e) { e.printStackTrace(); } } /** * Create the application */ public JPopupMenuTest() { initialize(); } /** * Initialize the contents of the frame */ private void initialize() { frame = new JFrame(); frame.setBounds(100, 100, 290, 234); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); final JPopupMenu popupMenu = new JPopupMenu(); addPopup(frame.getContentPane(), popupMenu); final JMenuItem newItemMenuItem = new JMenuItem(); newItemMenuItem.setText("New Item"); popupMenu.add(newItemMenuItem); popupMenu.addSeparator(); final JCheckBoxMenuItem newCheckboxCheckBoxMenuItem = new JCheckBoxMenuItem(); newCheckboxCheckBoxMenuItem.setText("New CheckBox"); popupMenu.add(newCheckboxCheckBoxMenuItem); final JMenu menu = new JMenu(); menu.setText("New SubMenu"); popupMenu.add(menu); final JMenuItem newItemMenuItem_1 = new JMenuItem(); newItemMenuItem_1.setText("New Item"); menu.add(newItemMenuItem_1); final JCheckBoxMenuItem newCheckboxCheckBoxMenuItem_1 = new JCheckBoxMenuItem(); newCheckboxCheckBoxMenuItem_1.setText("New CheckBox"); menu.add(newCheckboxCheckBoxMenuItem_1); final JRadioButtonMenuItem newRadiobuttonRadioButtonMenuItem_1 = new JRadioButtonMenuItem(); newRadiobuttonRadioButtonMenuItem_1.setText("New RadioButton"); menu.add(newRadiobuttonRadioButtonMenuItem_1); final JRadioButtonMenuItem newRadiobuttonRadioButtonMenuItem = new JRadioButtonMenuItem(); newRadiobuttonRadioButtonMenuItem.setText("New RadioButton"); popupMenu.add(newRadiobuttonRadioButtonMenuItem); } private static void addPopup(Component component, final JPopupMenu popup) { component.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent e) { if (e.isPopupTrigger()) showMenu(e); } public void mouseReleased(MouseEvent e) { if (e.isPopupTrigger()) showMenu(e); } private void showMenu(MouseEvent e) { popup.show(e.getComponent(), e.getX(), e.getY()); } }); }}

托盘？我用jni实现过，纯java应该不行吧。
最近研究swt，不知道有没有托盘功能。
