    • 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")
