Examples of javax.swing.InputVerifier

javax.swing.InputVerifier
program demonstrates the use of the Swing InputVerifier class. // It creates two text fields; the first of the text fields expects the // string "pass" as input, and will allow focus to advance out of it // only after that string is typed in by the user. public class VerifierTest extends JFrame { public VerifierTest() { JTextField tf1 = new JTextField ("Type \"pass\" here"); getContentPane().add (tf1, BorderLayout.NORTH); tf1.setInputVerifier(new PassVerifier()); JTextField tf2 = new JTextField ("TextField2"); getContentPane().add (tf2, BorderLayout.SOUTH); WindowListener l = new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit(0); } }; addWindowListener(l); } class PassVerifier extends InputVerifier { public boolean verify(JComponent input) { JTextField tf = (JTextField) input; return "pass".equals(tf.getText()); } } public static void main(String[] args) { Frame f = new VerifierTest(); f.pack(); f.setVisible(true); } } @since 1.3
