怎样创建一个系统托盘图标

Question

谁有现成的列子不给我一个  谢谢了 急

Answer 1

JDK1.6新增了一个java.awt.SystemTray来实现托盘图标。
JDK1.5的得用windows的ＡＰＩ来实现了。

        trayItem.setImage(image);
    }
}需要导入一些包,最主要的是swt.jar 

Answer 3

需要JDK1.6才能使用
    public void systemTray(){
        createPopupMenu();
        try {
            if (java.awt.SystemTray.isSupported()) {// 判断当前平台是否支持系统托盘
                java.awt.SystemTray  st = java.awt.SystemTray.getSystemTray();
                Image image = Toolkit.getDefaultToolkit().getImage(getClass().getResource("/res/server.png"));//定义托盘图标的图片
                java.awt.TrayIcon ti = new java.awt.TrayIcon(image);
                ti.setToolTip("服务管理器");
                ti.setPopupMenu(popupmenu);    //为托盘添加右键菜单
                ti.addMouseListener(new java.awt.event.MouseAdapter() {
                    public void mouseClicked(java.awt.event.MouseEvent evt) {
                        if (evt.getClickCount()==2){
                            OpenServer();
                        }
                    }
                });
                st.add(ti);
            }
        } catch (Exception e) {
            
        }
    }
