Method Detail

draw

public void draw(SimGraphics g,
                 int fromX,
                 int toX,
                 int fromY,
                 int toY)

Called by a Network*Display instructing the edge to draw itself. The coordinates are screen coordinates and correspond to the center of the nodes. Edges to be drawn by a Network*Display must implement this interface. Typicaly, some line drawing method in SimGraphics is called, passing the remaining arguments to that method. For example

 public void draw(SimGraphics g, int fromX, int toX, int fromY, int toY) {

    g.drawLink(Color.red, fromX, toX, fromY, toY);

 }

 

The x and y coordinates are calculated by the Display from the position of the nodes to which this is an edge.
