All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable

Enclosing class:

JRoofView

protected class JRoofView.JRoofCanvas
extends JComponent

A class that displays the STELLA building and the roofs according to the images, blinking instances and offsets assigned to it. It is the swing representation for the JRoofView class, which hands over the actual roof representation to this class, which is responsible for drawing it.
