DK for ActiveX | TatukGIS_XDK11.IGIS_Viewer.LocateEx | Methods | Properties
Locate shapes on layers that are near _ptg, but closer than _prec distance. Still only the best one candidate is chosen from each layer.
// C# public ITGIS_ShapeAbstractList LocateEx( ITGIS_Point _ptg, double _prec, WordBool _visible );
' VisualBasic Public Function LocateEx( ByVal _ptg As ITGIS_Point, ByVal _prec As Double, ByVal _visible As WordBool ) As ITGIS_ShapeAbstractList
// Oxygene public function LocateEx( _ptg : ITGIS_Point; _prec : Double; _visible : WordBool ) : ITGIS_ShapeAbstractList;
| Name | Type | Description |
|---|---|---|
| _ptg | ITGIS_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 | WordBool | if true the only visible shapes will be evaluated; shapes turned of by query of hidden will be ignored |
| Type | Description |
|---|---|
| ITGIS_ShapeAbstractList | Allocated list of shapes from all viewer layers |
