如何捕获trayicon.displayMessage（）鼠标点击工具提示气球
嗨，我想在用户点击消息气球工具提示后显示更详细的信息。
但是，我找不到如何捕获该事件。
这可能吗？
1）可以通过将ActionListener添加到TrayIcon来监听MouseClickEvents，然后Message body侦听MouseClicked
2）（没有直接询问）但我不能给你一个答案，如果消息是通过关闭按钮关闭，消息以同样的方式离开屏幕，但没有捕获任何事件
3）看起来像这个Java TrayIcon消息关闭按钮应该只是一个解决方案，因为API没有实现另一种方法，
import java.awt.*; import java.awt.event.*; public class FullTray { private static class ShowMessageListener implements ActionListener { private TrayIcon trayIcon; private String title; private String message; private TrayIcon.MessageType messageType; ShowMessageListener(TrayIcon trayIcon, String title, String message, TrayIcon.MessageType messageType) { this.trayIcon = trayIcon; this.title = title; this.message = message; this.messageType = messageType; } public void actionPerformed(ActionEvent e) { trayIcon.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("Message Clicked"); } }); trayIcon.displayMessage(title, message, messageType); } } public static void main(String args[]) { Runnable runner = new Runnable() { public void run() { if (SystemTray.isSupported()) { final SystemTray tray = SystemTray.getSystemTray(); Image image = Toolkit.getDefaultToolkit().getImage("gifIcon.gif"); PopupMenu popup = new PopupMenu(); final TrayIcon trayIcon = new TrayIcon(image, "The Tip Text", popup); MenuItem item = new MenuItem("Error"); item.addActionListener(new ShowMessageListener(trayIcon, "Error Title", "Error", TrayIcon.MessageType.ERROR)); popup.add(item); item = new MenuItem("Warning"); item.addActionListener(new ShowMessageListener(trayIcon, "Warning Title", "Warning", TrayIcon.MessageType.WARNING)); popup.add(item); item = new MenuItem("Info"); item.addActionListener(new ShowMessageListener(trayIcon, "Info Title", "Info", TrayIcon.MessageType.INFO)); popup.add(item); item = new MenuItem("None"); item.addActionListener(new ShowMessageListener(trayIcon, "None Title", "None", TrayIcon.MessageType.NONE)); popup.add(item); item = new MenuItem("Close"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { tray.remove(trayIcon); } }); popup.add(item); try { tray.add(trayIcon); } catch (AWTException e) { System.err.println("Can't add to tray"); } } else { System.err.println("Tray unavailable"); } } }; EventQueue.invokeLater(runner); } private FullTray() { } } 虽然这个话题不是最近的，但我想我会分享我的解决方案，因为这种事情并没有真正改变。
如何使用
要使用此代码，只需创建1个公共类和2个公共接口。
现在创建一个CustomTrayIcon类的实例，并在初始化之后调用addToSystemTray（）方法。
只要您想显示通知气泡，请调用showBubbleNotification（…）方法。
要删除此托盘图标，只需调用removeFromSystemTray（）方法即可。
CustomTrayIcon
这个类是完成所有繁重工作的基础。
