It has a very simple API and implementation, but it is very easy to use as well:
// Minimum password length is 6
final int passwordMinimumLength = 6;
// Create password field
final PasswordTextField passwordField = new PasswordTextField();
passwordField.addValidator(new MinLengthValidator(passwordMinimumLength));
addAndReplaceElement(passwordField, "passwordField");
// Create validation result panel
ValidationResultPanel passwordValidationResultPanel = new ValidationResultPanel(passwordField);
addAndReplaceElement(passwordValidationResultPanel, "passwordValidationResultPanel");
// Create password quality meter
final PasswordQualityMeter passwordQualityMeter = new PasswordQualityMeter(passwordMinimumLength);
addAndReplaceElement(passwordQualityMeter, "passwordQualityMeter");
// Validate field and update password quality meter on every key press
passwordField.addKeyUpHandler(new KeyUpHandler()
{
@Override
public void onKeyUp(KeyUpEvent event)
{
passwordQualityMeter.setPassword(passwordField.getFieldValue());
passwordField.forceAndVisualizeValidation();
}
});
