Yes. Yet I am unable to do it!

I read many of us asking for this need, but no one of the answers seem
to solve the problem.

As a sample I have a frame with only a jTextField and two jButtons
(jButton1 and jButton2).

I would like to fire automatically the jButton2 hitting ENTER when I am
writing in the jTextField.

Can anyone write for me the code to do this?

Thank you. Franco.

Just add the same ActionListener to both. That way the same will happen
when you hit enter on the textfield or press the button. Use a different
listener (or a way to distinguish the source, eg event.getSource()) for the
second button.

ActionListener myActionListener = new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
// ...
}
};

textField.addActionListener(myActionListener);
button.addActionListener(myActionListener);
button2.addActionListener(new ActionListener
{
// ...
});

Hi.

You solved me also this problem ( before you suggest me the solution
for the statusbar at the bottom of a frame).

This is a new step for me in learning and using Java. Thank you.

A more generic solution for this is to use the "defaultButton" property
of the rootPane on the Window/Frame/Dialog. See the API docs for the
setDefaultButton method in the class javax.swing.JRootPane.
