Detailed Description

This is a callback used to draw a series of lines.

A developer would implement a class derived from this one that has a GraphicsWindow pointer within it. This is the base class used by DrawLineProc and BoxLineProc. Below is the code from DrawLineProc showing how this is used: class DrawLineProc:public PolyLineProc {

GraphicsWindow *gw;

DrawLineProc() { gw = NULL; }

DrawLineProc(GraphicsWindow *g) { gw = g; }

int proc(Point3 *p, int n)

{ gw->polyline(n, p, NULL, NULL, 0, NULL); return 0; }

void SetLineColor(float r, float g, float b)

{gw->setColor(LINE_COLOR,r,g,b);}

};

Typically a developer would not have to use this class, but would rather use Class DrawLineProc, and Class BoxLineProc.
