Interface GraphDrawingPack.VertexDrawingInterface

public interface VertexDrawingInterface
extends Object

VertexDrawingInterface: all methods needed to draw vertices on canvas. In order to change how vertices are drawn, one would have to implement this interface, and then change the instantiation of this interface in GraphPack.Vertex.java

VertexinRect(double, double, double, double): return true if this vertex is in rectangle specified
drawVertex(GraphCanvas): draw vertex v on canvas
drawVxorTrans(GraphCanvas, int, int): draw vertex v translated by xtrans and ytrans, painted in xor mode note - draws v as if it were highlighted, but without border
ptInVertex(GraphCanvas, double, double): return true if pt(x,y) is in this vertex

drawVertex

  public abstract void drawVertex(GraphCanvas gc)

draw vertex v on canvas

drawVxorTrans

  public abstract void drawVxorTrans(GraphCanvas gc,
                                     int xtrans,
                                     int ytrans)

draw vertex v translated by xtrans and ytrans, painted in xor mode note - draws v as if it were highlighted, but without border

ptInVertex

  public abstract boolean ptInVertex(GraphCanvas gc,
                                     double x,
                                     double y)

return true if pt(x,y) is in this vertex

VertexinRect

  public abstract boolean VertexinRect(double x,
                                       double y,
                                       double x2,
                                       double y2)

return true if this vertex is in rectangle specified
