All Implemented Interfaces:

Feedback, InvalidKeyFeedback

Direct Known Subclasses:

HurlingWindowFeedback

public class BasicInvalidKeyFeedback
extends BasicFeedback
implements InvalidKeyFeedback

Provides feedback by beeping using the default toolkit and disabling the default button in the root pane for SafeKeyProvider.MIN_KEY_RETRY_DELAY milliseconds when prompting for a key and the last input was invalid.

Note that the root pane is normally the root pane of a parent JOptionPane which has the OK button set as its default button. This is to inhibit the use of a GUI robot for exhaustive password searching.

feedback

public void feedback(JPanel panel)

Description copied from class: BasicFeedback

Starts the visual/audible feedback. This method is called when the panel is shown in its containing window. It is run on AWT's Event Dispatch Thread, so it must complete fast in order not to block the GUI. If an implementation is going to do animations, the Timer class should be used to schedule timer events for the animation.

The implementation in this class simply beeps using the default toolkit.

Specified by:

feedback in interface Feedback

Overrides:

feedback in class BasicFeedback

Parameters:

panel - the panel to provide visual/audible feedback to.
