Class FrameFactory

  • public class FrameFactory
extends java.lang.Object
    Static class for drawing 2D frames.

    All shapes are drawn inside a bounding rectangle whose lower left corner is at the origin. Shapes with a leader use an offset point that indicate where the leader triangle should point at - it usually has a negative y since the leader connects at the bottom of the frame (at y = 0).
