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.
// 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;
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 |
Type | Description |

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