How to Make Flex Spark Text fit within Given Dimensions

Question

I have a multi-line Label, with user-defined text, that must fit inside some given dimensions.

<s:HGroup width="400" height="250">
  <s:Label id="myText" width="100%"/>
</s:HGroup>

I would like to adjust the font size of myText at runtime, depending on the content of myText.text. What is the best way to do this?

Answer 1

Unfortunately there is no API call or even a straightforward way of doing this. The only way to do this is to iterate over font sizes and check if the text fits within bounds.
