In short if the TrayIcon class was a JComponent then you can simply apply html tags to it. Therefore, to simulate what you need I will use the jdic.jar from https://jdic.dev.java.net/servlets/ProjectDocumentList?expandFolder=4183&folderID=5497.

import javax.swing.*;
import org.jdesktop.jdic.tray.*;
import java.awt.BorderLayout;
import java.awt.event.*;

public class SystemTrayDemo extends JFrame 
{
	public TrayIcon trayIcon;
	public JDialog dialog;

	public SystemTrayDemo() 
	{

		JPopupMenu menu = new JPopupMenu("Menu");
		JMenuItem menuItem1 = new JMenuItem("Menu1");
		menu.add(menuItem1);

		JMenuItem menuItem2 = new JMenuItem("Menu2");
		menu.add(menuItem2);

		JMenuItem menuItem3 = new JMenuItem("Menu3");
		menu.add(menuItem3);

		JMenuItem menuItem4 = new JMenuItem("Exit");
		menu.add(menuItem4);

		menuItem4.addActionListener(new ActionListener() 
		{
			public void actionPerformed(ActionEvent evt) 
			{
				System.exit(0);
			}
		});

		ImageIcon icon = new ImageIcon("middle.gif");
		trayIcon = new TrayIcon(icon, "Hello System Tray", menu);

		SystemTray tray = SystemTray.getDefaultSystemTray();
		tray.addTrayIcon(trayIcon);
		trayIcon.addActionListener(new ActionListener() 
		{
			public void actionPerformed(ActionEvent e)
			{
				dialog = new JDialog();
				dialog.add(new JLabel("Title"), BorderLayout.NORTH);
				dialog.add(new JLabel("Message"), BorderLayout.CENTER);
				dialog.add(new JLabel(new ImageIcon("middle.gif")),BorderLayout.SOUTH);
				dialog.setLocation(trayIcon.getLocationOnScreen().x - 50,trayIcon.getLocationOnScreen().y - 105);
				dialog.setVisible(true);
				dialog.setSize(100, 100);
				dialog.setResizable(false);
				dialog.addMouseListener(new MouseAdapter() 
				{
					public void mouseReleased(MouseEvent e) 
					{
						dialog.dispose();
					}
				});
			}
		});
	}

	public static void main(String[] args) 
	{
		new SystemTrayDemo();
	}
}

The presentation of it is close to aero peek in windows 7.

Hope this helps.

Hi !

I think you didn't understand my question.
I want to display the IconImage on the top-left of the title .

For example,

trayIcon = new TrayIcon(icon, "Hello System Tray", menu);

must be change to

trayIcon = new TrayIcon(icon, "<img src="image.gif">Hello System Tray",menu);

if we can use html tags in our code !

Thanks anyways !

Can anybody help me ?

Best regards !

Re: Beautiful tooltip for TrayIcon [modified]

10-Sep-09 17:58

I understood your question, if you read my first line "If the trayicon class was a Jcomponent then we can use html tags". You can display (as a balloon) the message type error,info,etc... use these in place of the dialog code depending on type:

trayIcon.displayMessage("Title", "Message", trayIcon.INFO_MESSAGE_TYPE);  
trayIcon.displayMessage("Title", "Message", trayIcon.NONE_MESSAGE_TYPE); 
trayIcon.displayMessage("Title", "Message", trayIcon.WARNING_MESSAGE_TYPE); 
trayIcon.displayMessage("Title", "Message", trayIcon.ERROR_MESSAGE_TYPE);

otherwise what your asking can only be done if you write your own package.

If using a JDialog or JFrame or JPanel to display an image(instead of the tooltip of TrayIcon) i think it is very simple and i didn't post my question.

I posted this question because i saw the "beautiful tooltip" of trayIcon of windowXP "your computer might be at risk". The Iconimage of the tooltip is not in (WARNING,INFO,ERROR,NONE) images.

I'm waiting for a solution for this because Microsoft did it !

Any other ideas ?

Best regards !

I was cruising around to see if their is any third party packages that can do what your asking and I stumbled upon an article on codeproject.com but its not in Java its using windows pressentation foundation but it does exaclty what you ask:

http://www.codeproject.com/KB/WPF/wpf_notifyicon.aspx

All you need now is to get Visual C# express and get the risk icon (what i did in windows 7 rc go to windows firewall and click on turn of firewall you will get the red x snap it using the snap tool and go to photoshop to do some editing and you can then save it as 16 x 16 icon and name it Inactive.ico) then copy it and place it in the c:\...wpf-notifyicon\Sample Project\Icons folder, then rebuild the code and run, you will find at the bottom right corner custom notification message.

Hope this helps. I will try to ask sun about it but you said it your self Microsoft did it with their language not Java

i want to develop a software by which once can remotely access one system, the program should be such that is should be platform independent, as in, a apple system can remote login a ubuntu system and the controls for the mouse, screen and board is transferred.

Also let me know, how to enable which port in that case, as port is dependent on the operating system as in 3389 for windows, 5900 for ubuntu i guess, any pointers for that.
Please let me know.

0. Remove you're e-mail address - it's a big invite to the Vikings.
1. Have you tried some diagnostics? Put some logging into your code and find out where things are going Lady Gaga, then post a nice little snippet to show what's gone wrong with an explanation of what you tried.
2. ??
3. Profit.

Panic, Chaos, Destruction.

Sending an Email in Java (Servlet)

Prerequisites:
1. Java Mail API (mail.jar)
2. activation.jar
3. HTML Form (Optional)
4. Servlet or JSP (to send the email)

Steps:
1. Download and install JDK6U16
2. Download Apache Tomcat
3. Download Eclipse
4. In Eclipse, make sure to add the apache server first
5. Create a dynamic web project
6. Under the WEB-INF create a folder called lib and paste mail.jar and activation.jar
7. Create a jsp and call it index.jsp
8. Create a servlet and call it sendMail
9. Create a class called MyPasswordAuthenticator (will act as authentication or you can use the code inside the sendMail as you like)
10. Create two jsps (success and error)
11. Create a css file called style

index.jsp Code:

<html>
<head>
<title>Sending email</title>
<link rel="stylesheet" href="style.css" type="text/css">
</head>
<body>
<center>
<form action="sendMail" method="get">   
<table>
<tr>
<td>From</td>
<td><input type="text" name="from"></td>
</tr>
<tr>
<tr>
<td>To</td>
<td><input type="text" name="to"></td>
</tr>
<tr>
<td>Subject</td>
<td><input type="text" name="subject"></td>
</tr>    
<tr>
<td>Message</td>
<td><textarea cols="25" rows="8" name="message"></textarea></td>
</tr>
</table>
<br>
<input type="submit" value="submit">
</form>
</center>
</body>
</html>

style.css

* { font-size: 12px; font-family: Verdana }
input, textarea { border: 1px solid #ccc }

1. Download rar from above.
2. Open it using Eclipse (JDK6U16)
3. When you provide your account make sure its in the format email@gmail.com

All done.

To setup a personal smtp read this guide:

Yes it is sufficient, after extracting the rar open it using Eclipse (with apache) then modify

String username = "your gmail account"; // in the form myemail@gmail.com
String password = "your gmail password";

then launch index.jsp and your done.

Good luck
