Selecting all text when clicking or pressing TAB on JTextField

Question

How can I set up the JTextField so that, when the user clicks on it or presses the TAB key, the text of JTextField is selected?

Answer 1

Add a FocusListener to the JTextField, and in focusGained(), call selectAll().

In code, this looks like this:

yourTextField.addFocusListener(new FocusListener() {
    @Override
    public void focusGained(FocusEvent e) {
       ((JTextField)e.getSource()).selectAll();
    }

    @Override
       public void focusLost(FocusEvent e) {}
});
