When invalid input is entered into the JSpinner, a beep is played, and I can't figure out how to disable it.
I'm using a number spinner with invalid input not being allowed to be typed in, like so:
public class SpinnerTester {
public static void main(String[] args) {
JSpinner spinner = new JSpinner(new SpinnerNumberModel(1, 0, 100, 1));
//disable invalid input from being typed into spinner
JFormattedTextField textField = ((JSpinner.NumberEditor) spinner.getEditor()).getTextField();
((NumberFormatter) textField.getFormatter()).setAllowsInvalid(false);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(spinner);
frame.setVisible(true);
frame.pack();
}
}
I do not know if there is a better way, but one way is to make a custom look and feel that disables beeping altogether. This achieves the desired effect, but also disables beeping for the entire program, not just the spinner.
public class SpinnerTester {
public static void main(String[] args) {
JSpinner spinner = new JSpinner(new SpinnerNumberModel(1, 0, 100, 1));
//disable invalid input from being typed into spinner
JFormattedTextField textField = ((JSpinner.NumberEditor) spinner.getEditor()).getTextField();
((NumberFormatter) textField.getFormatter()).setAllowsInvalid(false);
/**
* Change look and field
*/
try {
UIManager.setLookAndFeel(new MyLookAndFeel());
} catch (UnsupportedLookAndFeelException e) {
e.printStackTrace();
}
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(spinner);
frame.setVisible(true);
frame.pack();
}
/**
* Create Look and Feel without beeps
*/
public static class MyLookAndFeel extends NimbusLookAndFeel {
@Override
public void provideErrorFeedback(Component component) {
//super.provideErrorFeedback(component);
}
}
}
