TMS VCL WebGMaps
Creating a polygon in C++

This code snippet shows how to create a triangle polygon on WebGMaps with C++. First a path is created, the three points of the triangle are added and with the path, a polygon is added and created on the map:
{
  TPolygonItem *pol;
  TPath *pt;
  TPathItem *pi;

  pt = new TPath();

  pi = pt->Add();
  pi->Latitude = 50;
  pi->Longitude = 2;

  pi = pt->Add();
  pi->Latitude = 50;
  pi->Longitude = 3;

  pi = pt->Add();
  pi->Latitude = 55;
  pi->Longitude = 2.5;


  pol = WebGMaps1->Polygons->Add(false, false, false, pt, clRed, clYellow, 255, 255, 2, true, 255);

  WebGMaps1->CreateMapPolygon(pol->Polygon);
}
