How to know which leaf node i click and how to add a listener to each node?
hi! hello to all members, i have a problem i know how to create a listener, but i dont know how to add a listener to each leaf node. here is the scenario i want to do, i have a JTree where theres a topic that you can select on each leaf node, so when the user click the specific topic it will open another JFrame,which i dont know how to do it also, that its! the next problem will be how do i know which leaf node i select, so that i can open a right topic before the JFrame will open?please, i am very need this to solve quickly as possible. thanks again to all members.
What you have to do is to add a mouse listener on your JTree. Try something like this:
tree.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseReleased(MouseEvent e) {
tree_mouseReleased(e);
private void tree_mouseReleased(MouseEvent e) {
TreePath selPath = tree.getSelectionPath();
// Check If the click is the Right Click
if (e.isPopupTrigger() == true) {
// This is your right Click
else {
// This is your Left Click
}Your other problem: Set the userObject on nodes and on left click compare it with your object, if it matches, display the appropriate file. Alternatively, if your nodes are unique, you can match the names to open the file.
Hope this Helps

i want to add event listener when i click on a button in mxml, the event listener should be added in the action script file, how to do this?
can anyone help? urgent!!!Hi Lakshmi,
You can do this just put all the script in the mxml block in seperate AS file as shown below... Observe that I have included an AS file named Script.as and removed the script block form mxml and moved to this Script.as file. Place the Script.as file in your src folder ....
// Main mxml file....
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="onCreationComplete()">
<mx:Script source="Script.as"/>
<mx:TextArea id="textArea" width="300" height="100" />
<mx:Button id="myButton" label="Click ME"/>
</mx:Application>
//Script.as file
import mx.controls.Alert;
private function onCreationComplete():void
myButton.addEventListener(MouseEvent.CLICK, onButtonClick);
private function onButtonClick(event:MouseEvent):void
Alert.show("Button is Clicked");

How to add a Listener to the JLabel
Hi,
I am doing a Designer module in which i want to Listen Focus gained event on JLabel. For that i have added FocusListener to the JLabel but it does not listen to this event. (i think because of JLabels extraodinary property).
So How to add listener to the JLabel?Set the label to be focusable. This will allow it to gain focus from the
keyboard (from pressing TAB, for example), but not from being clicked on.
It's easy to give some demo code than to explain it:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class LabelListening extends MouseAdapter implements FocusListener {
private static final String TEXT_KEY = "jlabel_text_key";
public void focusGained(FocusEvent e) {
JLabel label = (JLabel) e.getComponent();
String text = (String) label.getClientProperty(TEXT_KEY);
label.setText("<html><u>" + text + "</u></html>");
public void focusLost(FocusEvent e) {
JLabel label = (JLabel) e.getComponent();
String text = (String) label.getClientProperty(TEXT_KEY);
label.setText(text);
public void mousePressed(MouseEvent e) {
e.getComponent().requestFocusInWindow();
public static void main(String[] args) {
LabelListening app = new LabelListening();
JPanel contentPane = new JPanel();
for(int i=0; i<4; ++i) {
String text = "label " + i;
JLabel label = new JLabel(text);
label.putClientProperty(TEXT_KEY, text);
label.setFocusable(true);
label.addFocusListener(app);
label.addMouseListener(app);
contentPane.add(label);
JButton btn = new JButton("a button");
btn.setBorderPainted(false);
btn.setContentAreaFilled(false);
btn.setMargin(new Insets(0,0,0,0));
contentPane.add(btn);
final JFrame f = new JFrame("");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setContentPane(contentPane);
f.pack();
SwingUtilities.invokeLater(new Runnable(){
public void run() {
f.setLocationRelativeTo(null);
f.setVisible(true);
}In this example, I have the focused label underlined. I don't
know what your context is, but it may be simpler just to work with
buttons instead. I "undecorate" a button in this example to make it look
similar to a label. -
How to add action listener to internal frame?
I have frame Main where I am trying to add action listener.
Action listener should be listening button in frame Menu.
I think it should be:
Menu frame = new Menu();
frame.btn_start.addActionListener(this);but it seems to be doing absolutely nothing.
If I try to add in menu:
btn_start.addActionListener(new Main());it generates: java.lang.StackOverflowError
What should I do? Please help noob :)To get better help sooner, post a [_Short, Self Contained, Compilable and Executable, Example Program (SSCCE)_|http://mindprod.com/jgloss/sscce.html] that clearly demonstrates your problem.
You're quite possible adding the ActionListener to the wrong component. And constructing a new instance of a class within the constructor is likely the cause of your StackOverflowError.

Hi!
The problem is that I have inherited the class MyTrayIcon from TrayIcon with implementing of MouseListener interface to handle mouse double click. But TrayIcon doesn't have method 'addMouseListener' as MyTrayIcon doesn't. So, how can I add listener is this case?How about looping through the array of listeners and
removing it if it's an instance of ListListener?
if (eventListeners[index] instanceof ListListener)
removeMouseListener(eventListeners[index]);I thought of that, but as I said i my post, eventListeners[] is protected.
How about writing your own ListListener in the
appropriate package which does precisely nothing, and
making sure it goes in the CLASSPATH before the
package you're supposed to use?Nice idea, but unfortunately, when I submit the assignment I have no way of making sure that it does go into the classpath before the package.
Thanks for your help, but I think I'll have to stick with the workaround.
It's not too hard: public static void setListData(DefaultListModel model, Object data[])
model.clear();
for (int i = 0; i < data.length; i++)
model.addElement(data); -
How to add mouse listener for a single row alone
I have a requirement. In a JTable when I double click a particular row the cells in the row should set to the width which I have provided.
The problem with my code is when I click fourth row in the table, the first row gets adjusted.
So how I need help is
only if I click the first row, the first row cell size should get adjusted not when I click fourth row.
Similarly if I give some cell width and height for fourth row cells, then when I double click the fourth row, the fourth should alone get adjusted and not the other rows.
Hope I have explained clearly.
How can it be achieved?
Please find below my code. Everything is hardcoded. So it may look messy. Please excuse.

How to add a listener for enter key
I'd like to build a chatzone applcation just like msn. The application
has two textarea, one is for the messages sent and recieve and one is
for the message typing area. Just like MSN, I'd like to send the text
after the user pressed enter key. But my problem is I don't know how
to make a key listener. I've tried jTextArea1.addKeyListener() but I don't
know how to use it. Anyone can help me?
Thanks in advanceKeyListener is just an interface, so you could use:
public class MyKeyListener implements KeyListener
private JTextArea area = null;
public MyKeyListener (JTextArea area)
this.area = area;
// Don't care about a key being pressed.
public void keyPressed (KeyEvent e) {}
// Don't care about a key being typed.
public void keyTypes (KeyEvent e) {}
// We care about the key being released.
public void keyReleased (KeyEvent e)
// Check what key it is. Note sure if \n is the right one...maybe use the key codes.
if (e.getKeyChar () == '\n')
// The return key has been pressed and released, they really meant to press it!
// Get the last line of the text from the text area. This bits up to you...maybe
// store the last location of the caret and then read from that point up
// to the current point...
}You can also use a DocumentListener if you are using a JTextArea but this is a little bit more complex but may be better, DocumentListeners work on telling you about more macro changes to the document... -

Acrobat (8.1.2): How to add 'mapping name' (/TM)
The PDF spec (1.4) defines that every form field can have an (optional) mapping name (key is TM). Is there a way to set this mapping name with Acrobat Profession 8.1.2?
Thanks for any help,
ToM
From the PDF spec 1.4 pp. 531:
(Optional; PDF 1.3) The mapping name to be used when exporting interactive
form field data from the document.There are a number of ways to execute the relevant JavaScript, from using the JavaScript console, to setting up a custom menu item or toolbar button, to using a batch sequence. I would probably construct a list of field name/mapping name value pairs and use the JavaScript console to run the code that sets the submitName.
To check whether the fields in a PDF have a mapping name set, you could again use JavaScript to loop through the collection of fields and get the value of the submitName property. You could also set up a script on the server to report on the field names that were submitted.

How to add a listener for frame change
hello
Im quite new to jmf, and im writing a code which uses the webcam, but im stuck at a point where i want a listener which is called whenever the frame changes in the visualcomponent. so basically im looking for a frame changed listener to be added to the visual component instead of using a loop or a timer or something.
i just need a method to be called constantly along the stream coming from the webcam but which is consistent with the changing of the frames.
i would really appreciate any kind of help.
thank youi thought there would be a listener or something ready to do thisThere is. It's the Rendered interface, which has a callback everytime data is received. If you want to create a custom renderer that is triggered everytime data is available, you set a processor to use your renderer and when data is available, your process command will be called. Same as an event listener...but it's very advanced stuff to implement the renderer interface.
for example if u want to record a video ull need to capture every frame as soon as it comesNo, the video doesn't come to you a frame at a time. The video is already encoded somehow when you get it, so it's coming in as a stream just like it'll be going out to the file... It's a stream of bytes, not a stream of images... You're not digitizing here, you're transcoding. -
How to add event listener to datagrid ROW
I need to know if it is possible to have the datagrid rows execute a state change.
For example: I have a datagrid populated with various items, when one row is selected I want it to change the state of a part of the canvas it is in.
How is this possible? I can not give the row an id so I would not be able to say "when row is selected change state" because there is no way to tell what row is selected.
Help please. Thanks.See Flex 4 and MXDataGridItemRenderer.

Unable to add the Listener class in project .
Hi friends ,
I'm using deploytool of Sun's AppServer 8.2.
I'm not abel to add the Eventlistener class in the project.
In the Help Menu the given following discription to Add the Event Listener call
Web Application WAR File -> Event Listeners tabbed pane
1. Click Add to add an event listener to the Event Listener Classes list.
Locate any event listener classes contained in this WAR file in the drop-down list in the Event Listener Classes pane.
(note:There is no any drop-down list in in the Event Listener Classes pane.)
2. If the event listener class is not in the list, in the General tab, click Edit and to go to the Edit Contents dialog box where the event listener class can be added to the contents of the WAR file. Upon return the event listener class will be in the pull-down list.
(note:But the listener class is present in General tab ,WEB-INF->classes->listeners(In the Contents of the General tab.))
How could i resolved this , i mean how to add Event Listener Classes in project ?
(Same problem while adding error page and filter classes which are also present in the General tab)
Regards,
Sachin Warang.I suggest using NetBeans IDE 5.5, which integrates easily with various appservers, including Sun Java System Application Server.

In oracle 11g, we have the database running with listener port 1521. We would like to cretae another database using the same oracle home and add the new listener entry with different port. Please advise how to add another listener entry in existing listener. thanks
CKPT wrote:
Please do not provide such stupid advice.Thinking can cause stupid, so kill the stupidity.
The number of listeners required per server is ONE! Not 2,not 100, but ONE.
Also different ports are not required. No gain is made by setting up different listeners on different ports.
The listener is a BROKER only, there is NO PERMANENT contact.oracle@ckpt-oracle:> ps -ef|grep tns

Then how the two listeners are running of the same home?
They obviously can run from the same home. What they can't do is run on the same port.
