WhiteboardShapePolygon constructor.

Parameters:

id - String that uniquely identifies this WhiteboardObject

thickness - number of pixels that this object (or its border) should be thick

color - WhiteboardShapePolygon's color (or rather it's border)

points - list of WhiteboardPoint

fill - True is filled, false is unfilled

WhiteboardShapePolygon

public WhiteboardShapePolygon(String id,
                              int t,
                              Color c,

                              boolean fill,
                              AffineTransform at)

WhiteboardShapePolygon constructor.

Parameters:

id - String that uniquely identifies this WhiteboardObject

t - number of pixels that this object (or its border) should be thick

c - WhiteboardShapePolygon's color (or rather it's border)

m_points - list of WhiteboardPoint

fill - True is filled, false is unfilled

at - 2D affine transformation

Method Detail

isFill

public boolean isFill()

Returns the fill state of the WhiteboardObject.

Specified by:

isFill in interface WhiteboardObjectPolygon

Returns:

True is filled, false is unfilled.

setFill

public void setFill(boolean fill)

Sets the fill state of the WhiteboardObject. True is filled, false is unfilled.

Specified by:

setFill in interface WhiteboardObjectPolygon

Parameters:

fill - The new fill state.

paintShape

public void paintShape(Graphics2D g,
                       AffineTransform t)

Code to paint the WhiteboardShapePolygon.

Specified by:

paintShape in class WhiteboardShape

Parameters:

g - graphics context

t - 2D affine transform

getSelectionPoints

public List<WhiteboardPoint> getSelectionPoints()

Returns the list of selected WhiteboardPoints.

Specified by:

getSelectionPoints in class WhiteboardShape

Returns:

list of selected WhiteboardPoints

contains

public boolean contains(Point2D p)

Tests if the shape contains a point.

Specified by:

contains in class WhiteboardShape

Parameters:

p - coord point

Returns:

true if shape contains p

getPoints

public List<WhiteboardPoint> getPoints()

Returns a list of all the WhiteboardPoint instances that this WhiteboardObject is composed of.

Specified by:

getPoints in interface WhiteboardObjectPolygon

Returns:

the list of WhiteboardPoints composing this object.

setPoints

public void setPoints(List<WhiteboardPoint> points)

Sets the list of WhiteboardPoint instances that this WhiteboardObject is composed of.

Specified by:
