Description
Creates object find for objects at specified point within specified radius. The funtion is capable of iterating
FUNCTION FindObjAtPt_Create(
hContainer :HANDLE;
objOptions :INTEGER;
travOptions :INTEGER;
locX :REAL;
locY :REAL;
pickRadius :REAL) : LONGINT;
def vs.FindObjAtPt_Create(hContainer, objOptions, travOptions, locX, locY, pickRadius): return LONGINT
Parameters
hContainer HANDLE objOptions INTEGER travOptions INTEGER locX REAL locY REAL pickRadius REAL
Remarks
(Orso, 2011): Was undocumented, made public by VW 2012 (1700).
(Orso, 2008-10-15): Finds objects at the point "Loc" starting from the parent container "hContainer". The routine returns a longint as list of objects (similar to BuildResourceList) which you'll use to manipulate the found objects. The suffix "create" stays then for "create a list".
FindObjAtPt_GetCount(list) will return the count of found objects FindObjAtPt_GetObj(list, i) returns a handle to the object at index "i. The index is 0-based.
It seems to ignore most object types. It will work with: lines, polylines, polygons, rectangles, arcs, 2D loci, pios Notably it will ignore: walls, symbols, round rects, ovals, 3D polys, 3D loci, nurbs, extrudes, dimensions, slabs....
