有没有event可以在任务托盘图标通知气球上调用的java,即

trayIcon.displayMessage(title, message, TrayIcon.MessageType.INFO)

就像 dropbox 使用的一样,当我点击气球时,它会将我带到下载最近文件的文件夹。可以使用java吗?

通过做一些研发,double click event当我们点击通知气球时,我得到了那个托盘图标。这就是我一直在寻找的。

检查此代码:

public class Main {
  static Image image = Toolkit.getDefaultToolkit().getImage("images/tray.gif");

  static TrayIcon trayIcon = new TrayIcon(image, "Tester2");

  public static void main(String[] a) throws Exception {
    if (SystemTray.isSupported()) {
      SystemTray tray = SystemTray.getSystemTray();

      trayIcon.setImageAutoSize(true);
      trayIcon.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
          System.out.println("In here");
          trayIcon.displayMessage("Tester!", "Some action performed", TrayIcon.MessageType.INFO);
        }
      });

      try {
        tray.add(trayIcon);
      } catch (AWTException e) {
        System.err.println("TrayIcon could not be added.");
      }
    }
  }
}

我以这种方式为我修改了它。

private static String location = Roor_Location_Here// contain the root location

然后在双击event

/*
 * Double click action performed *
 */
trayIcon.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        try {
            Desktop dst = Desktop.getDesktop();
            dst.open(new File(location));
            /*
             * reset the location to root location again.
             */
            location = Root_Location_Here // again setting root location                    
        } catch (Exception ex) {
            logger.error("------- error with folder opening double click "
                    + ex.getMessage());
        }
    }
});

这是我用来调用通知气球以显示消息的功能:

public static void showNotification(String title, String msg,
            String location) {
    if (SystemTray.isSupported()) {
        trayIcon.displayMessage(title, msg, TrayIcon.MessageType.INFO);
        SystemTrayGUI.location = location;// this sets the location that should be opened when balloon is clicked.

    }
}
