Setting the Focus of a JTextField Component Using a JLabel Component
This example associates a label with a text field using
setLabelFor(). A mnemonic is set on the label. When the mnemonic
keystroke is pressed, the text field will gain the focus.
In the following example, when ALT-L is pressed, the text field
gains the focus.
// Create text field
JTextField textfield = new JTextField(25);
// Create label and associate with text field
JLabel label = new JLabel("Text Label");
label.setDisplayedMnemonic(KeyEvent.VK_L);
label.setLabelFor(textfield);
