TGIS_Viewer.LocateEx method

DK11 for Java | tatukgis.jdk.TGIS_Viewer.LocateEx | Constructors | Fields | Methods | Properties | Events

Locate shapes on layers that are near _ptg, but closer than _prec distance. Still only the best one candidate is chosen from each layer.

Available also on: Delphi | .NET | ActiveX | Python.

Syntax

// Java
public TObjectList<TGIS_ShapeAbstract> LocateEx(
  TGIS_Point _ptg,
  double _prec,
  bool _visible
);
// Oxygene
public
  function LocateEx(
    _ptg : TGIS_Point;
    _prec : Double;
    _visible : Boolean
  ) : TGIS_ShapeAbstractList;

Parameters

Name Type Description
_ptg TGIS_Point reference point /searching point/
_prec double
Double
precision /not a longer distance than/; for points inside the polygon (if _prec >= 0) the distance will be multiply by 0.95 (to prefer points inside the polygon) but will not be bigger then _prec; for point distance will be multiplied by 0.9 to prefer points over lines and polygons; precision is express in map units
_visible bool
Boolean
if true the only visible shapes will be evaluated; shapes turned of by query of hidden will be ignored

Result

Type Description
TObjectList<TGIS_ShapeAbstract>
TGIS_ShapeAbstractList
Allocated list of shapes from all viewer layers

Remarks

returned list should be freed by a calling application.
