How to build a Flex FormItem with an image button in the label section?

I want to build a flex FormItem extension that adds a button into the item label section, such that there is both a text label and, to the right of it, a button that uses an image icon:

Basically, I want to create that 'i' icon, such that I can click on it to display a help overlay for the item in question.

Is there an existing component that does this? If not, how do I do it?


Try to use grid, gridrow, and grititem, like the html table. and add the label and the "i" image into a horizontal layout container inside the griditem.
