Constructor Details

GArc

public GArc(GArc e)

Copy constructor

Parameters:

e - GArc to copy

Throws:

IllegalArgumentException - if e is null

GArc

public GArc(int x,
 int y,
 int r,
 int a,
 int o)

Generates an arc of a circle

Parameters:

x - x coordinate of the center of the circle

y - y coordinate of the center of the circle

r - radius of the circle

a - angle of the arc (in degrees)

o - offset of the arc (in degrees)

GArc

public GArc(int x,
 int y,
 int w,
 int h,
 int a,
 int o)

Generates an arc of an oval

Parameters:

x - x coordinate of the lower left corner

y - y coordinate of the lower left corner

w - width of the rectangle

h - height of the rectangle

a - angle of the arc (in degrees)

o - offset of the arc (in degrees)

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

move

public void move(int x,
 int y)

Moves the center of this arc to the given coordinates

Parameters:

x - new x coordinate

y - new y coordinate

clone

public GArc 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
