All Known Implementing Classes:

public interface PuzzleGraphics
extends java.awt.event.MouseListener

Interface for graphical representations of logic puzzles. Classes implementing this interface can draw the clues and state of logic puzzles onto graphics objects. They can also handle mouse events, usually using mouse clicks to allow the user to solve the puzzle, or call a solver to solve it. This class may assume that it is only drawing in one place, i.e. when a mouse event is received, the coordinates are the same as in the last call to draw().

Method Summary
