示例8: doPaint
import java.awt.Graphics; //导入方法依赖的package包/类
/**
* doPaint is the method that handles the drawing of the box to the screen.
* Several variables and conditions affect how the image is drawn. First,
* the Unit.Length.Sim class variable <code>TO_PIXELS</code> performs the conversion between simulation
* length units (Angstroms) and pixels. The default value is 10 pixels/Angstrom
* reflecting the default size of the box (300 pixels by 300 pixels) and the
* default box size (30 by 30 A).
* The field <code>scale</code> is a multiplicative factor that directly
* scales up or down the size of the image; this value is adjusted automatically
* whenever shells of periodic images are drawn, to permit the central image and all
* of the specified periodic images to fit in the drawing of the box.
*
* @param g The graphic object to which the image of the box is drawn
