                       AffineTransform t)

Code to paint this WhiteboardShapeCircle

Specified by:

paintShape in class WhiteboardShape

Parameters:

g - graphics context

t - 2D affine transform

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

getSelectionPoint

public WhiteboardPoint getSelectionPoint(Point2D p)

Tests if a point p is on a selection point.

Specified by:

getSelectionPoint in class WhiteboardShape

Parameters:

p - point

Returns:

the nearest selection point

getSelectionPoints

public List<WhiteboardPoint> getSelectionPoints()

Returns the list of selected points

Specified by:

getSelectionPoints in class WhiteboardShape

Returns:

list of selected points

translate
