    • paint

      public void paint(JaxoGraphics2D g2, int x, int y)
      Paints an unmarked handle at (x, y).
      Parameters:
      g2 - The graphics context to paint to.
      x - The x position of the handle.
      y - The y position of the handle.

    • paint

      public void paint(JaxoGraphics2D g2, int x, int y, boolean marked)
      Paints a handle at (x, y).
      Parameters:
      g2 - The graphics context to paint to.
      x - The x position of the handle.
      y - The y position of the handle.
      marked - True if the handle should be marked (selected).

    • paint

      public void paint(JaxoGraphics2D g2, int x, int y, boolean marked, boolean secondary)
      Paint the handle at a given position.
      Specified by:
      paint in interface JaxoHandle
