Here is a function that will apply the default paragraph formatting to a TextRange. It takes a TextRange (textRange), a Pgf or TextLine (textObj), and the document object (doc). If you pass undefined as the textRange parameter, then the default formatting will be applied to the entire Pgf or TextLine. Note that for Pgf objects, the underlying paragraph format (PgfFmt) must exist in the document or the function will not change anything.

function applyDefaultParaFont (textRange, textObj, doc) {
    
    var pgfFmt, prop, textLoc;
    
    if (textRange) {
        if (textObj.constructor.name === "Pgf") {
            pgfFmt = doc.GetNamedPgfFmt (textObj.Name);
            if (pgfFmt.ObjectValid () === 1) {
                doc.SetTextProps (textRange, pgfFmt.GetProps ());
            }
        }
        else { // Text line
            textLoc = new TextLoc (textObj, 0);
            prop = doc.GetProps (textLoc);
            doc.SetTextProps (textRange, prop);
        }
    }
    else { // Apply to whole paragraph or text line.
        textRange = new TextRange (new TextLoc (textObj, 0),
            new TextLoc (textObj, Constants.FV_OBJ_END_OFFSET));
        if (textObj.constructor.name === "Pgf") {
            pgfFmt = doc.GetNamedPgfFmt (textObj.Name);
            if (pgfFmt.ObjectValid () === 1) {
                doc.SetTextProps (textRange, pgfFmt.GetProps ());
            }
        }
        else { // Text line
            textLoc = new TextLoc (textObj, 0);
            prop = doc.GetProps (textLoc);
            doc.SetTextProps (textRange, prop);
        }
    }

    prop = new PropVal ();
    prop.propIdent.num = Constants.FP_CharTag;
    prop.propVal.valType = Constants.FT_String;
    prop.propVal.sval = "";
    doc.SetTextPropVal (textRange, prop);
