Constructor Details

GOval

public GOval(GOval e)

Copy constructor

Parameters:

e - GOval to copy

Throws:

IllegalArgumentException - if e is null

GOval

public GOval(GRectangle r)
      throws IllegalArgumentException

Constructs an oval inscribed in a given rectangle

Parameters:

r - rectangle that will contain the oval

Throws:

IllegalArgumentException - if the rectangle is null

public GOval(int x,
 int y,
 int w,
 int h)
      throws InvalidArgumentException

Constructs an oval inscribed in a rectangle

Parameters:

x - x coordinate of the center of the rectangle

y - x coordinate of the center of the rectangle

w - horizontal size of the rectangle

h - vertical size of the rectangle

Throws:

InvalidArgumentException - if either h < 0 or w < 0

Method Details

draw

public void draw(Graphics2D g)

Description copied from class: GraphicE

Draws the component on the given graphics

Specified by:

draw in class GraphicE

Parameters:

g - where to draw

traslate

public void traslate(int x,
 int y)

Description copied from class: GraphicE

Traslates this element on X and Y

Specified by:

traslate in class GraphicE

Parameters:

x - size in px of the horizontal translation

y - size in px of the vertical translation

clone

public GOval clone()

Specified by:

clone in class GFillableE

hashCode

public int hashCode()

Overrides:

hashCode in class GFillableE

equals

public boolean equals(Object obj)

Overrides:

equals in class GFillableE

getShape

public Area getShape()

Description copied from class: GFillableE

This method should return a Area that represents the GFillableE. Since this is not always possible, and the implementation of Area isn't always easy, it should return null otherwise.
In jDrawingLibs implementation we use the default shapes for this. Note that this method is only called to create clips for Graphic objects

Specified by:

getShape in class GFillableE

Returns:

Shape
