Mapping ENTER as a Tab Event

[Watts]

How do using the ActionListener map the ENTER key as a TAB event? Effectively I want to generate a TAB keypressed when the user presses enter on a TextField.

Try just setting the focus to the next component on an enter key event via the requestFocus function.
Your component does have to know its successor for that though, which makes this solution actually a workaround when thinking OOP I - maybe somebody knows a better one:

this.addKeyListener(new KeyListener()
{
public void keyPressed(KeyEvent e)
{
if (e.getKeyCode() == KeyEvent.VK_TAB)
{
nextComponent.requestFocus();
}
}
});

Hope this helps
(note: if it does not compile or work: I did not test it #-))...

Hi Watts,

You can also set keycodes directly:

Panel p = new Panel(new GridLayout(1,2));
TextField tf = new TextField();
p.add(tf);

tf.addKeyListener(new KeyListener()
{
public void keyPressed(KeyEvent e)
{
if (e.getKeyCode() == KeyEvent.VK_ENTER)
{
e.setKeyCode(KeyEvent.VK_TAB);
}
}

public void keyTyped(KeyEvent e){}
public void keyReleased(KeyEvent e){}
});

Now when you press Enter at TextField it's mapped to TAB.

I hope that helped you.
