Method Detail

drawLine


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.

Parameters:
context - Identifies hosting region.
paintKey - Identifies the portion of the component being asked to paint, may be null.
g - Graphics object to paint to
x1 - x origin
y1 - y origin
x2 - x destination
y2 - y destination

drawLine 


 
public void drawLine ( SynthContext context,
 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.

Parameters:
context - identifies hosting region
paintKey - identifies the portion of the component being asked to paint, may be null
g - Graphics object to paint to
x1 - x origin
y1 - y origin
x2 - x destination
y2 - y destination
styleKey - identifies the requested style of the line (e.g. "dashed")
