Amy,

I had a look at your blog and it is kinda comforting to know that others too
have floundered getting to grips with itemRenderers.

As regards stepping through the Flex framework code, I have done that with the
textInput property of the ComboBox and it's just everywhere in the ComboBase
source.The textInput is in createChildren(), styleChanged(styleProp:String) -
where no less than 5 eventListener methods are attached, updateDisplayList,
setFocus, and isOurFocus(targetisplayObject). I think there comes a point
where overriding is just too troublesome so it might be best to start over and
learn the lessons from the Flex source. eg the dropdown is added via a
PopUpManager.addPopUp() call.

The itemRenderer remains a mystery I am afraid despite stepping through and
into the code carefully as it seems to be there in both 'this' and in the
dropdown it has.

You missed my point. Depending on what the _type_ they used for the
variable they refer to the textinput, you can simply delete it right after
it's created and replace it with something that's more to your
liking...which will then be acted on by all those other methods. If the
type actually is TextInput, you're SOL, but if it starts with I, for
example, that's an interface and there might be another object that
implements the same interface that you could use to replace it.

Hope this clarifies;

Amy
