Class ComponentAnimator

java.lang.Object
  com.vlsolutions.swing.docking.animation.ComponentAnimator

public class ComponentAnimator
extends java.lang.Object

Utility class used to perform move/resize animation for awt/swing components.

This class moves/resizes a Component given a start and end Rectangle and a duration.

Movements and listeners notifications are processed in the Swing Event Thread.

Field Summary

protected java.awt.Component	comp The animated component
protected float	duration the animation duration in seconds
protected float	elapsed time elapsed since the beginnig of animation
protected java.awt.Rectangle	endBounds the component's end bounds
protected java.awt.Rectangle	startBounds the component's start bounds

Constructor Summary

ComponentAnimator(java.awt.Component comp, java.awt.Rectangle startBounds, java.awt.Rectangle endBounds, float duration)
Reusable component animator.

ComponentAnimator(java.awt.Component comp, java.awt.Rectangle startBounds, java.awt.Rectangle endBounds, float duration, AnimationListener listener)
Single-shot animator (use another ComponentAnimator for a new animation).

Method Summary

void	addAnimationListener(AnimationListener listener) Adds a new listener to the animator
void	cancel() Cancels the animation (the component is not reset to its initial location/size)
float	getDuration() Returns the duration of the animation
java.awt.Rectangle	getEndBounds() Returns the end bounds of the components.
java.awt.Rectangle	getStartBounds() Returns the start bounds of the component.
void	setDuration(float duration) Sets the duration of the animation.
void	setEndBounds(java.awt.Rectangle endBounds) Sets the end bounds of the component.
void	setStartBounds(java.awt.Rectangle startBounds) Sets the start bounds of the component for animation.
void	start() Starts the animation.

Constructor Detail

ComponentAnimator

public ComponentAnimator(java.awt.Component comp,
                         java.awt.Rectangle startBounds,
                         java.awt.Rectangle endBounds,
                         float duration,
                         AnimationListener listener)

Single-shot animator (use another ComponentAnimator for a new animation).

Parameters:

comp - the component to animate

startBounds - initial bounds of the component

endBounds - end bounds of the component

duration - duration of animation, expressed in seconds

listener - single listener used for animation notification

ComponentAnimator

public ComponentAnimator(java.awt.Component comp,
                         java.awt.Rectangle startBounds,
                         java.awt.Rectangle endBounds,
                         float duration)

Reusable component animator. To start an animation, don't forget to call the start() method.

Method Detail

start

public void start()

Starts the animation.

The component is setBoundsed to startBounds and made visible, than a Swing timer is started to process the animation (refresh rate is 100 ms).

the ANIMATION_START event is then fired to all listeners.

cancel

public void cancel()

Cancels the animation (the component is not reset to its initial location/size)

addAnimationListener

public void addAnimationListener(AnimationListener listener)

Adds a new listener to the animator

Parameters:

listener - the listener

getDuration

public float getDuration()

Returns the duration of the animation

Returns:

the duration of the animation, in seconds

setDuration

public void setDuration(float duration)

Sets the duration of the animation.

Warning : do not change this value during an animation

Parameters:

duration - the new duration in seconds

getEndBounds

public java.awt.Rectangle getEndBounds()

Returns the end bounds of the components.

Returns:

the end bounds of the components.

setEndBounds

public void setEndBounds(java.awt.Rectangle endBounds)

Sets the end bounds of the component.

Warning : do not change end bounds during an animation.

Parameters:

endBounds -

getStartBounds

public java.awt.Rectangle getStartBounds()

Returns the start bounds of the component.

Returns:

the start bounds of the component (those of when animation starts).

setStartBounds

public void setStartBounds(java.awt.Rectangle startBounds)

Sets the start bounds of the component for animation.

Warning :do not change start bounds during an animation

Parameters:

startBounds - the start bounds of the component.
