  • Constructor Details Link icon

    • SynthGraphicsUtils Link icon

      public SynthGraphicsUtils()
      Creates a SynthGraphicsUtils.
  • Method Details Link icon

    • drawLine Link icon

      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 Link icon

      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")
