This should be rewritten:
pt1=eit->first->vertex(0)->point();
glVertex2d(pt1.x(),pt1.y());
pt2=eit->first->vertex(1)->point();
glVertex2d(pt2.x(),pt2.y());

as:

pt1=eit->first->vertex((eit->second+1)%3)->point();
glVertex2d(pt1.x(),pt1.y());
pt2=eit->first->vertex((eit->second+2)%3)->point();
glVertex2d(pt2.x(),pt2.y());

As you can see here:

typedef std::pair<Face_handle,int>
	Edge; 	The edge type. The Edge(f,i) is edge common to faces f and 
f.neighbor(i). It is also the edge joining the vertices vertex(cw(i)) 
and vertex(ccw(i)) of f.
