Binding Styles in Actionscript

Question

Friends,
I have a Actionscript component which ofcourse is completely
developed in Actionscript ... no mxml.
I need to bind the some of the styles like gutterLeft etc to
variables. How would I do it?
BindingUtils.bindProperty(myChartObject, "gutterLeft", this,
"MyVariable); ... will not work.

You can want all you want, but you can't force Flex to do
something in a way
that it isn't interested in doing it. When I was in college,
one of my guy
friends told me this story. He was out with some female
friends of ours and
the same guy kept asking one of them to dance. She kept
saying no, and the
guy finally said "But I really _want_ to dance with you. My
friend stepped
in and said "Yeah. We tend to want things."
The only way to change a style is to call setStyle.
