Size label font size to fit container

[Federico De Maddalena]

Hi!
is there an easy way to resize text of a spark label to fit container
size?

E.g.
<s:VGroup height="10%" width="100%">
        <s:Label width="100" text="...a long text..." id="label">
</s:VGroup >

I would set dynamically label fontSize, depending to label.text lenght.
TY
Federico
