public class DrawingPanel
- extends javax.swing.JPanel
- implements java.awt.event.ActionListener, Renderable
DrawingPanel renders drawable objects on its canvas.
DrawingPanel provides drawable objects with methods that transform from world
coordinates to pixel coordinates. World coordinates are defined by xmin, xmax,
ymin, and ymax. These values are recalculated on-the-fly from preferred
values if the aspect ratio is unity; otherwise, preferred values are used.
If xmax>xmin then the coordinate scale increases from right to left.
If xmaxymin then the coordinate scale increases from bottom to top.
If ymax
