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 tox1
- x originy1
- y originx2
- x destinationy2
- 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 regionpaintKey
- identifies the portion of the component being asked to paint, may be nullg
- Graphics object to paint tox1
- x originy1
- y originx2
- x destinationy2
- y destinationstyleKey
- identifies the requested style of the line (e.g. "dashed")- Since:
- 1.6
-
