class Node
{
public:
        Node(long id, long nid, float x, float y, float z)
        {
                fid = id;
                fnid = nid;
                fx = x;
                fy = y;
                fz = z;
                used = 0;
        }
        int used;
        float fx, fy, fz;
        long fid;
        long fnid;
};

 long cnvnodes()
{
  QPtrList<Node> nodes;
  nodes.append(new Node(nn, nrec, x, y, z));
}

 long cnvelems()
{
  int tn;
  QPtrList<Node> nodes;
  node = nodes.find(nodes.at(tn));
}

You are creating the QPtrList only inside a function and not return it in any point (the object is automatically destroyed in the function's end).

I recommend tha you change your functions to :

Source code

QPtrList<Node> cnvnodes()
{
  QPtrList<Node> nodes;
  nodes.append(new Node(nn, nrec, x, y, z));
  return nodes;
}


The second function I think is redundant.
