How to catch key events

Hello!
I have a component which extends JPanel. Now I dynamically add a JTextField as a child to this component. The problem is: when the textfield has focus, how can I get key events in my panel before the textfield gets them (and maybe intercept them so that the textfield doesn't get them at all)?
Background: the component is a self written table and the textfield is an editor. Now I have to make sure that when I am editing and press e.g. "cursor up", that not the textfield will get this key event but the table (which should traverse the current cell then ...)
The problem is: I cannot change the textfield (extend it or something) because a possible solution has to work with any java awt "Component" (or at least with JComponent).
Any help very appreciated.
Michael

Hello,
implement the keyListener interface for the Extended component...
and in Keypressed method
keyPressed(keyEvent){
// do all ur reuirements here
//and comsume the keyEvent...
hope this helps

How to catch key events in JWindow???

Can somebody please suggest me how do I catch key events in a JWindow. I tried without success with addKeyListener( ) method. My sample code is attached below. I've j2sdk1.4.2_03 in my PC.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class EventCatcher extends JWindow implements KeyListener {
     public EventCatcher() {
          super();
          Container c = getContentPane();
          setBounds(100,100,400,400);
          c.setLayout(new FlowLayout());
          JButton button = new JButton("Hello");
          c.add(button);
addKeyListener(this);
requestFocus();
setVisible(true);
     public void keyReleased(KeyEvent ke) {
System.out.println("**************");
     public void keyPressed(KeyEvent ke) {}
     public void keyTyped(KeyEvent ke) {}
     public static void main(String str[]) {
          new EventCatcher();

Catching key events in application

I have a JFrame with a JDesktop containing lots of JInternalFrame with various of components such as JTextFields etc.
Now, i want to have a "main" listener that will catch key events no matter which component that has focus. For example pressing CTRL+A should produce something in the application no matter which component that has focus.
How do I implement this in an easy way?

It doesnt seem to work to add a KeyListener to the JFrame...
this.addKeyListener(new KeyAdapter(){
               public void keyTyped(KeyEvent e){
                    System.out.println("KeyTyped()");
               public void keyPressed(KeyEvent e){
                    System.out.println("KeyTyped()");
          });Adding that to the JFrame gives nothing to System.out when a JTextArea inside an JInternalFrame has focus.

Hi,
You can set Destination URI on a graph. The URL can be specifically associated to a particular data point plotted in the graph.

Thanks, Sharon.

You need to write save button event handler for project information dialog. Link is having same functionality described.

How to consume key events

I would like to create a subclass of TextBox that only allows numeric input. My idea was to provide my own onKeyType() handler and consume any key events that do not correspond to digits. However, I can't find any way to consume key events from further processing. How do I do this?
Are there any other suggestions how to accomplish the task of providing your own filter concerning valid key input?
/Bengt

I also wanted a kind of validators for the TextBox class of JavaFX. So I've tried solving the problem using the SwingTextField class and some Java APIs. The following is my code for a SwingTextField accepting only digits, but I do want it to be much simpler.

import javafx.ext.swing.SwingTextField;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javax.swing.JComponent;
class DigitKeyEventHookListener extends AWTEventListener {
    public-init var source:JComponent;
    public override function eventDispatched( event:AWTEvent):Void {
        if (event.getSource().equals(source)) {
            var keyEvent : KeyEvent = event as KeyEvent;
            var keyCharacter = keyEvent.getKeyChar();
            var isDigit = false;
            var code = keyEvent.getKeyCode();
           if ((KeyEvent.VK_0 <= keyCharacter) and (keyCharacter <= KeyEvent.VK_9)) {
                   isDigit = true;
            if ((code ==KeyEvent.VK_DELETE) or (code ==KeyEvent.VK_BACK_SPACE)) {
                isDigit = true;
            if ((code ==KeyEvent.VK_LEFT) or (code ==KeyEvent.VK_RIGHT)) {
                isDigit = true;
           if (not isDigit) {
                keyEvent.consume();
function createSwingTextField() : SwingTextField{
    var field = SwingTextField {
        columns:12
    var listener = DigitKeyEventHookListener{
        source: field.getJTextField()
    Toolkit.getDefaultToolkit().addAWTEventListener(listener, AWTEvent.KEY_EVENT_MASK);
    return field;

How to catch call events?

Hi, I'm trying to develop a java application for mobile devices (mobile phones) that should automatically Reject when somebody calls (based on some rules).
I don't know how to catch the "+call event+".
Can anyone help me ?

Hi,
This is not possible using core Java ME (CLDC + MIDP). You can initiate a call in MIDP 2.0 by using platformRequest.
The optional JSR 253 makes it possible to do what you want do do, but I haven't seen any devices with this JSR implemented.

How to catch children events?

Hi all!
I have a problem. I thought it should be easy to implement, but I didn't found solution! :(
The problem is a next one: I have a JFrame that contains some components inside like Panels, Buttons, ... But what I need is a catch all mouse movements inside JFrame even if the event was appeared over these components.
Maximum what I could get is catch mose events over the empty space of JFrame.
Is anybody know how to do it?
Thank you!
Vladimir

Thank you,
That's exactly what I going to do today, but look at this http://forum.java.sun.com/thread.jsp?forum=57&thread=170512&start=0&range=15
That is what I searched for!
Anyway thanks a lot for your cooperation!

How to generate key events to a componet without keyboard

I want to generate a key event, a Keylistener is already there, (in fact, java3D's KeyNavigatorBehavior). I want to use other input methods instead of key pressings, so how I generate the key event manually
thx,

Look at java.awt.Robot. It has a keyPress() method to simulate key presses.

How to catch window event on jApplet

Could you please let me know, How to catch �activate window� event on Japplet page. I am using the following class.

}Edited by: samtek on Oct 30, 2007 7:59 PM
I extened my japplet class from WindowListener, and added function, windowActivated(), But not able to catch the event.

Hi,
I would try AWTEventListener; it should work with a JFrame.
Now I probably could have done this better but I made 2 classes for this.
HyperFrame to run the applet as an Application and have the Frame handle
the AWT events, and AWTEventManager to process the Events when running as an Applet. In the future I will probably merge into 1 AWTEventManager.
https://hyperview.dev.java.net/source/browse/hyperview/www/HyperView299/AWTEventManager.java?rev=1.3&view=markup
https://hyperview.dev.java.net/source/browse/hyperview/www/HyperView299/HyperFrame.java?rev=1.11&view=markup
Anyway, omit the View/List specific code and look at the setup; it should work for you. BTW Not ATM multi instance friendly but on my todo list several hundred down.
You will need to tweak the Thread control as well; probably AWTEventManager is the class to study as it really shows all you need to implement an AWTEventListener
Good Luck!
