TextLayoutFormat.fontFamily is null for a selection containing multiple fonts

first use richeditabletext.getformatofrange() retreive textlayoutformat object. attempt determine fonts used in selection textlayoutformat.fontfamily. works fine if 1 font set on selection. however, if type in 1 font, change font , type more, , select text containing both fonts, textlayoutformat.fontfamily return null. hope return comma-separated list or array of fonts used in selection. known bug/limitation, , if so, there workaround or plan address in future? kind of thing common use case our rich text input, , need figure out fonts selected.

 

i still using tlf framework came flex 4.0.

that's design.  property undefined when multi valued.  comma separated list wouldn't work anyhow that's legal value fontfamily - understand point in general.  want array each multi-valued property.

 

 

getformatofrange calling underlying selectionmanager function getcommoncharacterformat.

 

this code looks this:

 

    public function getcommoncharacterformat():textlayoutformat
    {      

        var firstleaf:flowleafelement = textflow.findleaf(absolutestart);

        var lastleaf:flowleafelement = textflow.findleaf(absoluteend);
        var leaf:flowleafelement = firstleaf;
        var attr:textlayoutformat = new textlayoutformat(leaf.computedformat);
       
        (;;)
        {
            if (leaf == lastleaf)
                break;
            leaf = leaf.getnextleaf();
            attr.removeclashing(leaf.computedformat);
        }

 

        return property.extractincategory(textlayoutformat, textlayoutformat.description, attr, category.character) textlayoutformat;
    }

 

for specialized behavior i'd suggest writing new version of function takes textflow, absolutestart , absoluteend parameters , makes calculation.  instead of returning textlayoutformat dictionary more appropriate.

 

hope helps,
