Looks like you want a 15 pixel gap (you are adding 15 in updateDisplayList) but that is not accounted for in the measure() method.

I will email the entire project in a zip file to flexcoders. the name of the file is TwoLines.zip The problem is, when I add the second line (in CreateChildren()), the label is pushed up away from the icon. I am sure I am doing something stupid. I have included a screen print of the output in the src directory of the .zip file.
