Method Detail

getShape

public Polygon3D getShape()

Returns the 3-d polygon which this object fills up.

Returns:

the object's polygon

drawOn

public abstract java.awt.Shape drawOn(java.awt.Graphics2D g,
                                      Transformation trans)

Draws this object. This method should draw the object, as transformed by trans, on g. The method should return a Shape, indicating the region which it covered. This is to enable the container to deliver mouse events.

Parameters:

g - the graphics object on which to draw

trans - the transformation to use

Returns:

the region of space which was filled

Parameters:

l - the listener

removeMouseListener

public void removeMouseListener(java.awt.event.MouseListener l)

Removes the specified listener from receiving mouse events from this component.

Parameters:

l - the listener

addMouseMotionListener

public void addMouseMotionListener(java.awt.event.MouseMotionListener l)

Registers the specified listener to receive mouse motion events from this component.

Parameters:

l - the listener
