Paul,

Thanks for replying.  I'm sorry to have made you type so much but my problem
is much simpler than what you thought.

I have a dialog with bunch of controls one of which is the OK button.  What
I want is that should the user press Enter when this dialog has been
activated,  then the actionPerformed of the OK button should be executed
(even if the cursor is currently in , say, a text field).   Hope this makes
sense.

George

I think you are looking for this: 
dialog.getRootPane().setDefaultButton(submitButton);

Paul & Alex,

Thanks a lot!  I had forgotten all about root panes.  Haven't been there for 
the longest time :-)

There is one little "feature" that you should be aware of.  If one of 
the controls in your page is a "TextArea", then it will be capturing the 
"Enter" key when it has focus.  That's really just a "gotcha" that you 
can't really do anything about, unless you want to break the 
functionality of the TextArea.

I am not exactly sure what you are asking, but I will take a stab at making
an assumption.


You have a Dialog and you want to activate the Event listener on another
JFrame or JPanel. The solution is to get the instance of that parent
container.

The easiest way to do this, is to have a static instance of the container
you wish to access. Example:

public class MyJPanel extends JPanel {

  static MyJPanel panel;


  public MyJPanel() {
   super();
   
  }

  public static MyJPanel getMyJPanel(){
    if(panel==null){
      panel= new MyJPanel();
    }
   return panel;
  }



  //Now call the getMyJPanel from the Dialog
   
  public void jDialogButton1_actionPerformed(ActionEvent actionEvent) {
     MyJPanel panel=MyJPanel.getMyJPanel();
         panel.jButton2_actionPerformed(null);
  }

  Of course another and a much better way to do thisand avoid dependencies
upon your view Components, is to create Listener class(es) that will
implement listeners according to usage in the application. Those listeners
that would be commonly used in the application or which need to be able to
access methods across Frames, Dialogs, etc. could have static references or
be contained in a static class. This enforces better separation between
classes. Since I do not know your programming background, I do not know
what to reference as a a concept here. If you have database programming
background, think of a linking table concept.

Whew,

You do not want much, do you :)


OK, here is how I made it work.

First, you will need to define an AbstractEvent (I am doing this in the
jbInit() method)



public void jbInit() throws Exception {
  //All of the normal initialization code first. Dots below represent code.  
  //DO NOT TYPE THE DOTS!!
  ..............

   //Put this code in your code.. Of course change the names to your
   // component names
//replace with your JDialog name
     final SimpleDialog sd=(SimpleDialog)this;
 //Create a new AbstractAction javax.swing.AbstractAction
     javax.swing.Action anAction = new javax.swing.AbstractAction() {
          public void actionPerformed(ActionEvent e) {
           //assuming jButton1 is your name and the actionPerformedEvent
            sd.jButton1_actionPerformed(null);
          }
         };
          javax.swing.JComponent jc=(javax.swing.JComponent)
              sd.getComponent(0);
          jc.getInputMap(javax.swing.JComponent.WHEN_IN_FOCUSED_WINDOW).
            put(javax.swing.KeyStroke.getKeyStroke("ENTER"),"myAction");
          jc.getActionMap().put("myAction",anAction);
    }
  }  

That should do it for you..

This is definitely the easiest way for a single key event for a single
button and a single keystoke.
