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....

PROCEDURE xxxxx;
VAR
	cnt, i : INTEGER;
	startContainer : HANDLE;
	list : LONGINT;
	loc	: VECTOR;
		
BEGIN
	GetPt(loc.x, loc.y);
	startContainer := NIL;
	
	list := FindObjAtPt_Create(startContainer, 1, 0, loc.x, loc.y, 100);
	cnt := FindObjAtPt_GetCount(list);
	
	i := 0;
	WHILE i < cnt DO BEGIN
		AlrtDialog(Concat('Index: ', i, ' Obj Type: ', GetTypeN(FindObjAtPt_GetObj(list, i))));
		i := i + 1;
	END;
	FindObjAtPt_Delete( list );
END;
RUN(xxxxx);
