java.lang.Object | +--javax.swing.Timer
Causes an action to occur at a predefined rate. For
example, an animation object can use a Timer as the trigger for drawing its
next frame.
For documentation and examples of using timers, see
Each Timer has a list of ActionListeners and a delay (the time between actionPerformed() calls). When delay milliseconds have passed, a Timer sends the actionPerformed() message to its listeners. This cycle repeats until stop() is called, or halts immediately if the Timer is configured to send its message just once.
Using a Timer involves first creating it, then starting it using the start() method.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.

Constructor Summary | |
Timer(int delay,
ActionListener listener)
Creates a Timer that will notify its listeners every delay milliseconds. |
Method Summary | |
void |
addActionListener(ActionListener listener)
Adds an actionListener to the Timer |
protected void |
fireActionPerformed(ActionEvent e)
Notify all listeners that have registered interest for notification on this event type. |
int |
getDelay()
Returns the Timer's delay. |
int |
getInitialDelay()
Returns the Timer's initial delay. |
EventListener[] |
getListeners(Class listenerType)
Return an array of all the listeners of the given type that were added to this timer. |
static boolean |
getLogTimers()
Returns true if logging is enabled. |
boolean |
isCoalesce()
Returns true if the Timer coalesces multiple pending performCommand() messages. |
boolean |
isRepeats()
Returns true if the Timer will send a actionPerformed() message to its listeners multiple times. |
boolean |
isRunning()
Returns true if the Timer is running. |
void |
removeActionListener(ActionListener listener)
Removes an ActionListener from the Timer. |
void |
restart()
Restarts a Timer, canceling any pending firings, and causing it to fire with its initial dely. |
void |
setCoalesce(boolean flag)
Sets whether the Timer coalesces multiple pending ActionEvent firings. |
void |
setDelay(int delay)
Sets the Timer's delay, the number of milliseconds between successive actionPerfomed() messages to its listeners |
void |
setInitialDelay(int initialDelay)
Sets the Timer's initial delay. |
static void |
setLogTimers(boolean flag)
Enables or disables the timer log. |
void |
setRepeats(boolean flag)
If flag is false, instructs the Timer to send actionPerformed() to its listeners only once, and then stop. |
void |
start()
Starts the Timer, causing it to send actionPerformed() messages to its listeners. |
void |
stop()
Stops a Timer, causing it to stop sending actionPerformed() messages to its Target. |
