I have a 'JFrame'. with some Buttons and JComboBoxes. I have set one of the button as the 'DefaultButton'(To perform critical action whenever the user presses 'ENTER' key , no matter where the focus is ...) for this frame.

The problem is that whenever, the focus is on one of the JComboBoxes, the 'DefaultButton' is not getting the 'ENTER' action.

This is working fine with Sun JVM1.1.8. But not with Sun JVM1.3.0_02.

Any ideas how to fix it ???

Thanks...

vijaynatraj,

I am guessing you are using KeyListener to handle this "ENTER" action, right? You can also addKeyListener to the JComboBoxes as well and do the same thing as the default button does.

Hi Vijay,
 that's fine. what you do is in combbox listener method you redirect the enter key event to default button.
//button key listener method
 defaultButton_Key_Pressed(KeyEvent key){
  if(key.getKeyCode() == key.VK_ENTER){
    //do defaultButton action  
  }  
 }
//combobox key listener method
 jComb_Key_Pressed(KeyEvent key){
  if(key.getKeyCode() == key.VK_ENTER){
    defaultButton_Key_Pressed(key);
  }  
 }

 i hope it helps you.
