Class CompoundGraphic

java.lang.Object
  graphics.AbstractGraphic
      graphics.CompoundGraphic

All Implemented Interfaces:

CenterLocatable, IContainer, IGraphic, ILocatable, IRotatable, ISizeable, java.awt.image.ImageObserver

public class CompoundGraphic
extends AbstractGraphic
implements IContainer

A Graphical object that acts as a container for other Graphical objects. Add many Graphics to this and then moving, rotating, etc. this graphic will perform the desired action on all the Graphics this contains

Constructor Summary

CompoundGraphic()
Creates a new instance of an empty CompoundGraphic with a dimension of (1,1) at point (0,0)

Method Summary

void	actualPaint(java.awt.Graphics2D gs, java.awt.Point location, java.awt.Dimension dimension) Uses the Graphics2D object to Paint the CompoundGraphic at a specified location and with a specified dimension
void	add(IGraphic g) Adds a graphic to the compound
java.awt.Shape	getShape() Returns a java.awt.Shape that represents the total sum of the areas of all the Graphics in this Compound's Bounding box.
boolean	imageUpdate(java.awt.Image img, int infoflags, int x, int y, int width, int height)
void	remove(IGraphic g) Removes a Graphic from the Compound
void	repaint() Forces a repaint of all the Graphics in the same container as the Compound
void	repaint(java.awt.Rectangle bounds) Forces a repaint of all the things that are on this Container in the given bounds
void	setDimension(java.awt.Dimension newDimension) Sets the dimension of this compound, thus causing all the Graphics in the compound to be altered.

Constructor Detail

CompoundGraphic

public CompoundGraphic()

Creates a new instance of an empty CompoundGraphic with a dimension of (1,1) at point (0,0)

Method Detail

add

public void add(IGraphic g)

Adds a graphic to the compound

Specified by:

add in interface IContainer

Parameters:

g - The Graphic to add

See Also:

IContainer.add(graphics.IGraphic)

remove

public void remove(IGraphic g)

Removes a Graphic from the Compound

Specified by:

remove in interface IContainer

Parameters:

g - The Graphic to remove

See Also:

IContainer.remove(graphics.IGraphic)

actualPaint

public void actualPaint(java.awt.Graphics2D gs,
                        java.awt.Point location,
                        java.awt.Dimension dimension)

Uses the Graphics2D object to Paint the CompoundGraphic at a specified location and with a specified dimension

Specified by:

actualPaint in interface IGraphic

Parameters:

gs - The Graphics2D object that will do the painting

location - The Location at which to paint the Compound

dimension - The Dimension of the Compound

See Also:

IGraphic.actualPaint(java.awt.Graphics2D, java.awt.Point, java.awt.Dimension)

repaint

public void repaint()

Forces a repaint of all the Graphics in the same container as the Compound

Specified by:

repaint in interface IContainer

See Also:

IContainer.repaint()

repaint

public void repaint(java.awt.Rectangle bounds)

Description copied from interface: IContainer

Forces a repaint of all the things that are on this Container in the given bounds

Specified by:

repaint in interface IContainer

Parameters:

bounds - the bounds of which to repaint

See Also:

IContainer.repaint(java.awt.Rectangle)

imageUpdate

public boolean imageUpdate(java.awt.Image img,
                           int infoflags,
                           int x,
                           int y,
                           int width,
                           int height)

Specified by:

imageUpdate in interface java.awt.image.ImageObserver

Parameters:

img -

infoflags -

x -

y -

width -

height -

Returns:

I don't know

See Also:

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

setDimension

public void setDimension(java.awt.Dimension newDimension)

Sets the dimension of this compound, thus causing all the Graphics in the compound to be altered. Use with caution. It is much easier if the Dimensions of CompoundGraphics are set before any Graphics are inserted into it.

Specified by:

setDimension in interface ISizeable

Overrides:

setDimension in class AbstractGraphic

Parameters:

newDimension - The Dimension to set this CompoundGraphic to be

See Also:

ISizeable.setDimension(java.awt.Dimension)

getShape

public java.awt.Shape getShape()

Returns a java.awt.Shape that represents the total sum of the areas of all the Graphics in this Compound's Bounding box.

Specified by:

getShape in interface IGraphic

Returns:

an empty java.awt.Rectangle

See Also:

IGraphic.getShape()
