Direct Known Subclasses:

mxMorphing

public class mxAnimation
extends mxEventSource

Baseclass for all timer-based animations. Fires mxEvent.DONE when the stopAnimation method is called. Implement updateAnimation for the actual animation or listen to mxEvent.EXECUTE.

mxAnimation()
Constructs a new animation instance with the given repaint delay.

mxAnimation(int delay)
Constructs a new animation instance with the given repaint delay.

Method Summary

int	getDelay() Returns the delay for the animation.
boolean	isRunning() Returns true if the animation is running.
void	setDelay(int value) Sets the delay for the animation.
void	startAnimation() Starts the animation by repeatedly invoking updateAnimation.

Field Detail

DEFAULT_DELAY

public static int DEFAULT_DELAY

Specifies the default delay for animations in ms. Default is 20.

delay

protected int delay

Default is DEFAULT_DELAY.

timer

protected Timer timer

Time instance that is used for timing the animation.

Constructor Detail

mxAnimation

public mxAnimation()

Constructs a new animation instance with the given repaint delay.

mxAnimation

public mxAnimation(int delay)

Constructs a new animation instance with the given repaint delay.

Method Detail

getDelay

public int getDelay()

Returns the delay for the animation.

setDelay

public void setDelay(int value)

Sets the delay for the animation.

isRunning

public boolean isRunning()

Returns true if the animation is running.

startAnimation

public void startAnimation()

Starts the animation by repeatedly invoking updateAnimation.

updateAnimation

public void updateAnimation()

Hook for subclassers to implement the animation. Invoke stopAnimation when finished, startAnimation to resume. This is called whenever the timer fires and fires an mxEvent.EXECUTE event with no properties.

stopAnimation

public void stopAnimation()

Stops the animation by deleting the timer and fires mxEvent.DONE.
