public class SynthGraphicsUtils extends Object
Wrapper for primitive graphics calls.
public SynthGraphicsUtils()
Creates a SynthGraphicsUtils.
public void drawLine(SynthContext context,
Object paintKey,
Graphics g,
int x1,
int y1,
int x2,
int y2) Draws a line between the two end points.

Object paintKey,
Graphics g,
int x1,
int y1,
int x2,
int y2,
Object styleKey) Draws a line between the two end points.
This implementation supports only one line style key, "dashed". The "dashed" line style is applied only to vertical and horizontal lines.
Specifying null or any key different from "dashed" will draw solid lines.
