任务托盘通知气球事件？
是否可以在任务托盘图标通知气球上调用任何java event ，即
trayIcon.displayMessage(title, message, TrayIcon.MessageType.INFO)
就像Dropbox一样，当我点击气球时，它会把我带到它下载最近文件的文件夹。 是否可以使用java？
通过做一些研发，当我们点击通知气球时，我得到了托盘图标double click event 。 这就是我想要的。
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来显示消息的函数：
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. } }

您可以将ActionListener添加到SystemTray中的Message

例如
package misc; /* * TrayIconDemo.java */ import java.awt.*; import java.awt.event.*; import java.net.URL; import javax.swing.*; public class TrayIconDemo { public static void main(String[] args) { /* Use an appropriate Look and Feel */ try { // UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel"); } catch (UnsupportedLookAndFeelException ex) { } catch (IllegalAccessException ex) { } catch (InstantiationException ex) { } catch (ClassNotFoundException ex) { } /* Turn off metal's use of bold fonts */ UIManager.put("swing.boldMetal", Boolean.FALSE); //Schedule a job for the event-dispatching thread: //adding TrayIcon. SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } private static void createAndShowGUI() { //Check the SystemTray support if (!SystemTray.isSupported()) { System.out.println("SystemTray is not supported"); return; } final PopupMenu popup = new PopupMenu(); final TrayIcon trayIcon = new TrayIcon(createImage("images/bulb.gif", "tray icon")); final SystemTray tray = SystemTray.getSystemTray(); // Create a popup menu components MenuItem aboutItem = new MenuItem("About"); CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size"); CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip"); Menu displayMenu = new Menu("Display"); MenuItem errorItem = new MenuItem("Error"); MenuItem warningItem = new MenuItem("Warning"); MenuItem infoItem = new MenuItem("Info"); MenuItem noneItem = new MenuItem("None"); MenuItem exitItem = new MenuItem("Exit"); //Add components to popup menu popup.add(aboutItem); popup.addSeparator(); popup.add(cb1); popup.add(cb2); popup.addSeparator(); popup.add(displayMenu); displayMenu.add(errorItem); displayMenu.add(warningItem); displayMenu.add(infoItem); displayMenu.add(noneItem); popup.add(exitItem); trayIcon.setPopupMenu(popup); try { tray.add(trayIcon); } catch (AWTException e) { System.out.println("TrayIcon could not be added."); return; } trayIcon.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { JOptionPane.showMessageDialog(null, "This dialog box is run from System Tray"); } }); aboutItem.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { JOptionPane.showMessageDialog(null, "This dialog box is run from the About menu item"); } }); cb1.addItemListener(new ItemListener() { public void itemStateChanged(ItemEvent e) { int cb1Id = e.getStateChange(); if (cb1Id == ItemEvent.SELECTED){ trayIcon.setImageAutoSize(true); } else { trayIcon.setImageAutoSize(false); } } }); cb2.addItemListener(new ItemListener() { public void itemStateChanged(ItemEvent e) { int cb2Id = e.getStateChange(); if (cb2Id == ItemEvent.SELECTED){ trayIcon.setToolTip("Sun TrayIcon"); } else { trayIcon.setToolTip(null); } } }); ActionListener listener = new ActionListener() { public void actionPerformed(ActionEvent e) { MenuItem item = (MenuItem)e.getSource(); //TrayIcon.MessageType type = null; System.out.println(item.getLabel()); if ("Error".equals(item.getLabel())) { //type = TrayIcon.MessageType.ERROR; trayIcon.displayMessage("Sun TrayIcon Demo", "This is an error message", TrayIcon.MessageType.ERROR); } else if ("Warning".equals(item.getLabel())) { //type = TrayIcon.MessageType.WARNING; trayIcon.displayMessage("Sun TrayIcon Demo", "This is a warning message", TrayIcon.MessageType.WARNING); } else if ("Info".equals(item.getLabel())) { //type = TrayIcon.MessageType.INFO; trayIcon.displayMessage("Sun TrayIcon Demo", "This is an info message", TrayIcon.MessageType.INFO); } else if ("None".equals(item.getLabel())) { //type = TrayIcon.MessageType.NONE; trayIcon.displayMessage("Sun TrayIcon Demo", "This is an ordinary message", TrayIcon.MessageType.NONE); } } }; errorItem.addActionListener(listener); warningItem.addActionListener(listener); infoItem.addActionListener(listener); noneItem.addActionListener(listener); exitItem.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { tray.remove(trayIcon); System.exit(0); } }); } //Obtain the image URL protected static Image createImage(String path, String description) { URL imageURL = TrayIconDemo.class.getResource(path); if (imageURL == null) { System.err.println("Resource not found: " + path); return null; } else { return (new ImageIcon(imageURL, description)).getImage(); } } }
