One of the problems we encountered when developing Yooba Studio was getting access to a small but crucial part of a Flex Component: the CheckBox check icon.  In many cases, most of the parts of a component is accessible via relatively easy means, making it easy for developers to modify its behaviour and appearance. But the CheckBox (and the RadioButton) was a different story. We wanted to change the check mark color at runtime and after doing some digging, I found the hard coded color value in CheckBoxIcon.as. Creating my own version of the file (thanks Alex!) we were able to do just what we wanted with the icon.

An example of how to go about it can be found here.

This is an example of when the open code in the Flex SDK is of great value - without it things would have been much more difficult in the every-day coding.
