All Implemented Interfaces:

java.lang.Runnable

public class ImageScroller

extends java.lang.Object

implements java.lang.Runnable

Class for presenting a scrolling image on the back of a solitaire game.

While an object is being dragged by the container, no scrolling will occur

This could be made more generic (to allow scrolling up/down/left/right/random)...

Field Summary

protected Container	container Container over which we are operating; we need to have dragging.
protected int	delay Delay between scrolling.
protected int	edge The distance between the left edge and position of leading scrolled edge.
protected java.awt.Image	myImage Image being scrolled.
protected int	scrollDistance Distance to scroll horizontally with each clock tick.
protected java.lang.Thread	thread The thread to oversee the scrolling.
protected boolean	visible Assume we are originally visible.

Constructor Summary

ImageScroller(java.awt.Image img, Container container)
ImageScroller constructor.

Method Summary

int	getDelay() Return delay between image scrolling.
int	getScrollDistance() Return distance to scroll image.
boolean	isVisible() Determine whether image is visible.
void	run() Thread will operate by pausing n milliseconds and then checking if container is in a drag.
void	setDelay(int newDelay) Set the time delay between image scrolling.
void	setScrollDistance(int newScrollDistance) Set the distance to scroll each time.
void	setVisible(boolean newVisible) Setting to invisible will cause this thread to stop.
void	visit(RectangleHierarchy node) Copy the appropriate image onto Graphics g at (x,y,width,height) taking into account the scrolling image.
void	visit(RectangleHierarchy node, java.awt.Rectangle clip) Copy the appropriate image onto Graphics g at (x,y,width,height) taking into account the scrolling image.

Field Detail

myImage

protected java.awt.Image myImage

Image being scrolled.

delay

protected int delay

Delay between scrolling.

container

protected Container container

Container over which we are operating; we need to have dragging.

edge

protected int edge

The distance between the left edge and position of leading scrolled edge.

scrollDistance

protected int scrollDistance

Distance to scroll horizontally with each clock tick.

thread

protected java.lang.Thread thread

The thread to oversee the scrolling.

visible

protected boolean visible

Assume we are originally visible.

Constructor Detail

ImageScroller

public ImageScroller(java.awt.Image img,
                     Container container)

ImageScroller constructor.

Method Detail

getDelay

public int getDelay()

Return delay between image scrolling.

Returns:

int

getScrollDistance

public int getScrollDistance()

Return distance to scroll image.

Returns:

int

isVisible

public boolean isVisible()

Determine whether image is visible.

Returns:

boolean

run

public void run()

Thread will operate by pausing n milliseconds and then checking if container is in a drag. Once it is verified that we can scroll, we do so, and the entire container background is redrawn.

Specified by:

run in interface java.lang.Runnable

setDelay

public void setDelay(int newDelay)

Set the time delay between image scrolling.

Parameters:

newDelay - int

setScrollDistance

public void setScrollDistance(int newScrollDistance)

Set the distance to scroll each time.

Parameters:

newScrollDistance - int

setVisible

public void setVisible(boolean newVisible)

Setting to invisible will cause this thread to stop.

Parameters:

newVisible - boolean

visit

public void visit(RectangleHierarchy node)

Copy the appropriate image onto Graphics g at (x,y,width,height) taking into account the scrolling image.

visit

public void visit(RectangleHierarchy node,
                  java.awt.Rectangle clip)

Copy the appropriate image onto Graphics g at (x,y,width,height) taking into account the scrolling image.

Note: only Leaf nodes are drawn.

Note: In V2.1 fixed defect in missing clip argument to recursive calls!

Clip to the given Rectangle clip area. [clip is unaffected by this invocation.]
