Drawing Area Coordinates

["James J Hayes III" <JJHayesIII hotmail com>]

I'm trying to show a tooltip on my drawing area that displays the
coordinates of the pointer.  This is what I have:

static gint motion_notify_event( GtkWidget *widget,
                                 GdkEventMotion *event )
{
  gint x, y;
  gfloat x2, y2;
  char tmp[20];
  GdkModifierType state;

  if (event->is_hint)
    gdk_window_get_pointer (event->window, &x, &y, &state);
  else
    {
      x = event->x;
      y = event->y;
      state = event->state;
    }

  x2 = toscreenx(MaxDataX,MinDataX,MaxScreenX,MinScreenX,(gfloat)x);
  y2 = toscreeny(MaxDataY,MinDataY,MaxScreenY,MinScreenY,(gfloat)y);

  sscanf(tmp, "X=%f Y=%f",&x2,&y2);
  fprintf(stderr," %s ",tmp);
  gtk_tooltips_set_tip(GTK_TOOLTIPS(DataTT),drawing_area,tmp,NULL);

  if(GTK_WIDGET_NO_WINDOW(drawing_area)) fprintf(stderr,"NO WINDOW!");

  return TRUE;
}

I've added the events to the drawing_area, which is global....

Thanks in advance!
