Constructor Detail

FadingPanel

public FadingPanel()

Standard construtor.

Method Detail

addFadingPanelListener

public void addFadingPanelListener(FadingPanelListener listener)

Register a fadingpanel listener.

Parameters:

listener - DOCUMENT ME!

isFading

public boolean isFading()

Returns the fade status of the component.

Returns:

true is the component is actualy fading, else false

startFading

public void startFading(Component fadeFromComponent,
                        Component fadeToComponent,
                        long fadeDuration)

Fades from one component to an other, by first creating an image from both components. Then @see startFading(BufferedImage, BufferedImage, long)

Parameters:

fadeFromComponent - DOCUMENT ME!

fadeToComponent - DOCUMENT ME!

fadeDuration - DOCUMENT ME!

startFading

public void startFading(BufferedImage fadeFromImage,
                        BufferedImage fadeToImage,
                        long fadeDuration)

Fades an image to an other, in a specific duration of time. If the Component is still fading, then the timer is reseted. Else a new fade thread will be started.

Parameters:

fadeFromImage - the image to fade from

fadeToImage - the image to fade to

fadeDuration - the duration in ms for the fade animation

DOCUMENT ME!

Overrides:

paint in class Component

Parameters:

graphics - DOCUMENT ME!

ellapsedTime

public long ellapsedTime()

Returns the ellapsed time between now and the last start time.

Returns:

ellapsed time in ms

resetStartTime

public void resetStartTime()

createImageFromComponent

public static BufferedImage createImageFromComponent(Component component)

Creates an "alpha-compatible" buffered image from a given component.

Parameters:

component - the component

Returns:

the bufferd image
