public final class GraphDrawing
extends Object
implements GraphDrawingInterface

GraphDrawing: implements all methods for drawing the graph on canvas. The GraphCanvas contains one GraphDrawing object, each Vertex contains its own VertexDrawing object, and each Edge contains its own EdgeDrawing object.

Currently, vertices are drawn as rectangles which expand in size to contain the selected property (see VertexDrawing). Edges are arcs between vertices (see EdgeDrawing and DirEdgeDrawing). Edges are always drawn first so that the vertices cover the incoming edges.

GraphDrawing(GraphCanvas)

EdgeinRect(EdgeList, double, double, double, double): return true if edge e\'s midpoint is in the specified rectangle

addAllInRectToHV(double, double, double, double): highlight all vertices within specified rectangle
addAllInRectToHV_E(double, double, double, double): highlighted all vertices and edges within specified rectangle
drawAttachedEdges(Vertex): draw all edges attached to Vertex v
drawE(): draw all edges in graph
drawEdge(Edge): draw Edge
drawEdge(EdgeList)
drawEdge(Vertex, Vertex)
drawGraph(): draw all edges and vertices in graph
drawHE(): draw all highlighted edges in graph
drawHV(): draw all highlighted vertices in graph
drawHVtrans(int, int): draw all highlighted vertices translated by specified xtrans, ytrans
drawV(): draw all vertices in graph
drawVertex(Vertex): draw Vertex
drawvtrans(Vertex, int, int): draw vertex v translated by specified xtrans, ytrans
ptInEdge(EdgeList, double, double): return true if pt(x,y) is in active portion of the edge
ptInVertex(Vertex, double, double): return true if pt(x,y) is in this vertex
ptOnEdge(double, double): return the edge whoser active portion contains point (x,y)
