public class AnimatedGifWidget

extends ImageWidget

This widget is the same as the ImageWidget, except that it also frequently repaints new frames in an animated gif if the image is an animated image.

This widget is not a subclass of AnimatedWidget, because the fps property is different here (this widget uses a delay) and the AnimatedWidget is based on frames and a current frame, while this widget simply repaints the next frame whenever it arrives from the image.

This widget supports WidgetLayoutMgr2. This means it can be used in widgets/containers that use a layout manager that implements WidgetLayoutMgr2.

Field Summary

protected int	delay The delay in milliseconds between each frame of the animated gif, if the image being used is actually an animating gif.
protected java.util.Vector	oldImages Vector with Image objects that have been previously used, but are not used anymore since the image had to be refreshed.

Constructor Summary

AnimatedGifWidget()
Default public constructor.

AnimatedGifWidget(java.lang.String src)
Construct a new animated gif widget with the given image source.

Method Summary

void	flush() Flush the image cache.
int	getDelay() Get the delay between each frame in milliseconds.
void	getProperties(PropertyList list) Add the delay property to the properties of this widget.
boolean	imageUpdate(java.awt.Image newimg, int flags, int x, int y, int w, int h) Check whether the next frame of the image is ready.
void	setDelay(int delay) Set the delay between each frame in milliseconds.
void	setProperties(PropertyList list) Set the properties of this widget, including the delay property.
void	setValue(java.lang.String value) Store old image before flushing with new value, so imageUpdate can check for that old image and return false on it.

Field Detail

delay

protected int delay

The delay in milliseconds between each frame of the animated gif, if the image being used is actually an animating gif.

See Also:

getDelay(), setDelay(int)

oldImages

protected java.util.Vector oldImages

Vector with Image objects that have been previously used, but are not used anymore since the image had to be refreshed. The imageUpdate method returns false whenever it receives an old image, so that image won't be loaded anymore.

See Also:

imageUpdate(java.awt.Image, int, int, int, int, int)

Constructor Detail

AnimatedGifWidget

public AnimatedGifWidget()

Default public constructor.

AnimatedGifWidget

public AnimatedGifWidget(java.lang.String src)

Construct a new animated gif widget with the given image source.

Method Detail

getProperties

public void getProperties(PropertyList list)

Add the delay property to the properties of this widget.

Overrides:

getProperties in class ImageWidget

Following copied from class: marimba.gui.Widget

Parameters:

list - The list in which the current state needs to be saved.

See Also:

Widget.setProperties(PropertyList)

setProperties

public void setProperties(PropertyList list)

Set the properties of this widget, including the delay property.

Overrides:

setProperties in class ImageWidget

Following copied from class: marimba.gui.Widget

Parameters:

list - The list that contains the new widget state.

See Also:

Widget.getProperties(PropertyList)

getDelay

public int getDelay()

Get the delay between each frame in milliseconds.

See Also:

setDelay(int), delay

setDelay

public void setDelay(int delay)

Set the delay between each frame in milliseconds.

Parameters:

delay - the new delay in milliseconds

See Also:

getDelay(), delay

setValue

public void setValue(java.lang.String value)

Store old image before flushing with new value, so imageUpdate can check for that old image and return false on it.

Overrides:

setValue in class ImageWidget

See Also:

imageUpdate(java.awt.Image, int, int, int, int, int)

flush

public void flush()

Flush the image cache. This class stores the old image here before flushing the cache, so imageUpdate can check for that old image and return false on it.

Overrides:

flush in class ImageWidget

See Also:

imageUpdate(java.awt.Image, int, int, int, int, int)

imageUpdate

public boolean imageUpdate(java.awt.Image newimg,
