// C#
public TGIS_Point CentroidScope(
  string _query,
  TGIS_Point _centroid
);

' VisualBasic
Public Function CentroidScope(
  ByVal _query As String,
  ByVal _centroid As TGIS_Point
) As TGIS_Point

// Oxygene
public
  function CentroidScope(
    _query : String;
    _centroid : TGIS_Point
  ) : TGIS_Point;

Use this method to calculate a centroid for a scope, in fact this finds the centroid for the first shape.

When using this operation, never call any function which uses FindFirst..FindNext (any function which iterates through the shapes using it - so never use inside an operation like Locate, PaintScope etc.).
