Description

Returns string description of a value in the specified record field.
FUNCTION GetRField(
h  :HANDLE;
record  :STRING;
field  :STRING) : DYNARRAY[] OF CHAR;
def vs.GetRField(h, record, field):
    return DYNARRAY[] of CHAR

Parameters

h HANDLE Handle to object.
record STRING Name of record format.
field STRING Name of field to be queried.

Return Value

Returns the field value as a variable length string.

Remarks

(MaKro, June 2018):

To fetch the default values, use GetObject(GetName(GetParametricRecord(..))) as handle. Object Type of GetObject return value is 47 (Record Definition) vs. 48 (Record) from GetParametricRecord.

(Orso, 2015.02.24): Please note that since the introduction of ifc data, the usual praxis of fetching plug-in records using

GetRecord(h, NumRecords(h))

can bring you perhaps unexpectedly the ifc record. Use VS:GetParametricRecord instead, introduced from VW 2011.

(Others): Returns a string interpretation of the field from the specified record

[CLC 2001/11/12]: Note that when using this to access parameter fields in a PIO, you get the values of the instance of the plug-in, not the default values, as set in the plug-in editor. If you want the default values, you have to use the handle to the PIO record format.

[CLC 2004/11/8]: This returns values rounded to the nearest display accuracy, whereas pFieldName returns the actual number.

Example

VectorScript

PROCEDURE Example;

FUNCTION WriteFieldValues(h :HANDLE) :BOOLEAN;
VAR
cnt     :INTEGER;
recHand :HANDLE;
recName :STRING;
fldName :STRING;
BEGIN
recName := GetName(GetRecord(h, NumRecords(h))); { ... use GetParametricRecord(h) instead }
recHand := GetObject(recName);
FOR cnt := 1 TO NumFields(recHand) DO BEGIN
fldName := GetFldName(recHand, cnt);
WriteLn(fldName, ': ', GetRField(h, recName, fldName));
END;
END;

BEGIN
ForEachObjectInLayer(WriteFieldValues, 2, 0, 4);
END;
RUN(Example);

Python

import vs

hpio = vs.FSActLayer()
hrecdef = vs.GetParametricRecord(hpio)
recname = vs.GetName(hrecdef)  # Name of PIO in InfoPalette
hrec = vs.GetObject(recname)
fld = vs.GetFldName(hrec, 10)

vs.AlrtDialog(vs.GetTypeN(hrecdef))  # 48
vs.AlrtDialog(vs.GetTypeN(hrec))  # 47

vs.AlrtDialog('Recordname:' + recname)
vs.AlrtDialog('Default:' + vs.GetRField(hrec, recname, fld))
