Class BasicFeedback

java.lang.Object
  de.schlichtherle.key.passwd.swing.BasicFeedback

All Implemented Interfaces:

Feedback, Runnable

Direct Known Subclasses:

BasicCreateKeyFeedback, BasicInvalidKeyFeedback, BasicOpenKeyFeedback, BasicUnknownKeyFeedback

public abstract class BasicFeedback
extends Object
implements Feedback

Provides feedback by beeping using the default toolkit. If you would like to play a nice sound for feedback, you need to override the startSound() method.

Warning: Playing a java.applet.AudioClip on J2SE 1.4.2_12 causes a client application not to terminate until System.exit(0) is called explicitly - hence this feature is currently not implemented in this class! This issue is fixed in JSE 1.5.0_07 (and probably earlier versions).

TrueZIP 6.2

Method Detail

getPanel

public JPanel getPanel()

Description copied from interface: Feedback

Returns the panel which is used to provide feedback.

Specified by:

getPanel in interface Feedback

setPanel

public void setPanel(JPanel panel)

Description copied from interface: Feedback

Sets the panel which is used to provide feedback.

Specified by:

setPanel in interface Feedback

Parameters:

panel - The CreateKeyPanel to provide feedback.

run

public void run()

Starts the visual/audible feedback. Subclasses should not override this method directly, but override startSound() and/or startAnimation() instead.

The implementation in this class calls startSound() and then startAnimation().

Specified by:

run in interface Feedback

Specified by:

run in interface Runnable

startSound

protected void startSound()

Starts the audible feedback. Subclasses may override this method to play a sound of their liking.

startAnimation

protected void startAnimation()

Starts the visual feedback. Subclasses may override this method to animate the GUI according to their liking. 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 is a no-op.
