DrawSpline, help

[Tomasz Sienkiewicz]

Hi,


could you, please, tell me what am I doing wrong with DrawSpline ?
Straight line is all i can achieve.
My code:

Gathering points from onmotion (dragging) event

public: wxList point_list;

....
wxClientDC dc(this);
  wxPoint *point = new wxPoint ;
  point->x = (int) event.GetPosition().x;
  point->y = (int) event.GetPosition().x;
  point_list.Append((wxObject*)point);

.....

int pointsCount = point_list.GetCount();
           double           x1, y1;
           wxPoint pointy[pointsCount-1];
           wxPoint *p;
            wxList::compatibility_iterator node = point_list.GetFirst();
            int uu = 0;
              while (node)
              {
               p =(wxPoint *)node->GetData();

                   x1 = p->x;
                   y1 = p->y;

               wxPoint pkt = wxPoint((int)x1,(int)y1);
                pointy[uu]=pkt;

                node = node->GetNext();
                uu++;
              }
           dc.DrawSpline(WXSIZEOF(pointy),pointy);
