public class VertexDrawing
extends Object
implements VertexDrawingInterface

VertexDrawing: implements all methods for drawing vertices on canvas. Vertices are rectangles which contain the text of the selected vertex property. If no property is selected for display, the vertex is drawn as a rectangle of size stored in the GraphCanvas. Plain vertices are white framed in blue, and selected vertices are red framed in blue.

VertexDrawing(Vertex): set drawing methods for vertex _v

VertexinRect(double, double, double, double): return true if this vertex is in rectangle specified
drawVertex(GraphCanvas): draw this vertex on GraphCanvas
drawVxorTrans(GraphCanvas, int, int): draw vertex 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

VertexDrawing

  public VertexDrawing(Vertex _v)

set drawing methods for vertex _v

drawVertex

  public void drawVertex(GraphCanvas gc)

draw this vertex on GraphCanvas

drawVxorTrans

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

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

ptInVertex

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

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

VertexinRect

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

return true if this vertex is in rectangle specified
