Class ShapeGroup

java.lang.Object
  wheelsunh.etc.AbstractGraphic
      wheelsunh.users.AbstractShape
          wheelsunh.users.ShapeGroup

All Implemented Interfaces:

java.awt.event.MouseListener, java.util.EventListener, CustomGraphic, Locatable, Rotatable

public class ShapeGroup
extends AbstractShape
implements Locatable, Rotatable, java.awt.event.MouseListener

A class representing a group of Shapes which can be moved as a single entity. The group also registers clicks and keystrokes on its members; by default, it takes no action, but this behavior can be overridden in subclasses. The group's nominal location is the upper left-hand corner of a nominal rectangle enclosing all the shapes in the group (in other words, the smallest x and y coordinates in the group).

Constructor Summary

ShapeGroup()
Constructor: defines xloc and yloc to be arbitrarily large; the first shape will set them appropriately.

Method Summary

void	add(AbstractShape s) Adds a shape to this group.
boolean	contains(java.awt.Point p) returns true if p is contained within any shape in this group
java.awt.Rectangle	getBounds() returns the bounding box of this group
int	getHeight() Returns the object's height
java.awt.Point	getLocation() Returns the object's location.
int	getRotation() returns the current absolute degree of rotation of this group By Jake Mandel, for UNH CS
java.util.Set<AbstractShape>	getShapes() Return a Set of all shapes in this group.
int	getWidth() Returns the object's width
int	getXLocation() Returns the object's x location.
int	getYLocation() Returns the object's y location.
void	mouseClicked(java.awt.event.MouseEvent e) Called when mouse is clicked over the graphic.
void	mouseDragged(java.awt.event.MouseEvent e) Called when mouse button is pressed and dragged over graphic.
void	mouseEntered(java.awt.event.MouseEvent e)
void	mouseExited(java.awt.event.MouseEvent e)
void	mousePressed(java.awt.event.MouseEvent e) Called when a mouse button is pressed over the graphic.
void	mouseReleased(java.awt.event.MouseEvent e) Called when a mouse button is released over the graphic.
void	paint(java.awt.Graphics2D g) The real meat of the interface.
void	setLocation(java.awt.Point p) Set object's location to given point.
void	setRotation(int degrees) sets the rotation angle of this ShapeGroup to (degrees) absolute This method handles repositioning the shapes, then rotates each of them separately.

Constructor Detail

ShapeGroup

public ShapeGroup()

Constructor: defines xloc and yloc to be arbitrarily large; the first shape will set them appropriately.

Method Detail

add

public void add(AbstractShape s)

Adds a shape to this group. The group's "location" is adjusted if necessary, and the new shape is registered with this group as a mouse and keystroke listener

setLocation

public void setLocation(java.awt.Point p)

Set object's location to given point.

Specified by:

setLocation in interface Locatable

Specified by:

setLocation in class AbstractShape

contains

public boolean contains(java.awt.Point p)

returns true if p is contained within any shape in this group

Specified by:

contains in interface CustomGraphic

Parameters:

p - the point

getLocation

public java.awt.Point getLocation()

Returns the object's location.

Specified by:

getLocation in interface Locatable

Specified by:

getLocation in class AbstractShape

getBounds

public java.awt.Rectangle getBounds()

returns the bounding box of this group

Specified by:

getBounds in class AbstractShape

getXLocation

public int getXLocation()

Returns the object's x location.

Specified by:

getXLocation in interface Locatable

Specified by:

getXLocation in class AbstractShape

getYLocation

public int getYLocation()

Returns the object's y location.

Specified by:

getYLocation in interface Locatable

Specified by:

getYLocation in class AbstractShape

getWidth

public int getWidth()

Returns the object's width

Specified by:

getWidth in class AbstractShape

getHeight

public int getHeight()

Returns the object's height

Specified by:

getHeight in class AbstractShape

getRotation

public int getRotation()

returns the current absolute degree of rotation of this group By Jake Mandel, for UNH CS

Specified by:

getRotation in interface Rotatable

Specified by:

getRotation in class AbstractShape

setRotation

public void setRotation(int degrees)

sets the rotation angle of this ShapeGroup to (degrees) absolute This method handles repositioning the shapes, then rotates each of them separately. By Jake Mandel, for UNH CS

Specified by:

setRotation in interface Rotatable

Specified by:

setRotation in class AbstractShape

getShapes

public java.util.Set<AbstractShape> getShapes()

Return a Set of all shapes in this group.

paint

public void paint(java.awt.Graphics2D g)

Description copied from interface: CustomGraphic

The real meat of the interface. The graphic must know how to draw itself using the passed-in instance of Graphics2D. This method will be called often (whenever the containing drawing panel is repainted).

Specified by:

paint in interface CustomGraphic

Parameters:

g - the Graphics2D you should use to paint your graphic

mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

Description copied from class: AbstractGraphic

Called when a mouse button is pressed over the graphic.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Specified by:

mousePressed in interface CustomGraphic

Overrides:

mousePressed in class AbstractGraphic

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

Description copied from class: AbstractGraphic

Called when a mouse button is released over the graphic.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Specified by:

mouseReleased in interface CustomGraphic

Overrides:

mouseReleased in class AbstractGraphic

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

Description copied from class: AbstractGraphic

Called when mouse is clicked over the graphic.

Specified by:

mouseClicked in interface java.awt.event.MouseListener

Specified by:

mouseClicked in interface CustomGraphic

Overrides:

mouseClicked in class AbstractGraphic

mouseDragged
