Hi all, I've got a problem that I want set the scrollbar of a richlistbox elmenet to hide or show dynamically, but it seems that I can't get the scrollbar element directly, only the richlistbox itself, or the scrollbox inside the richlistbox. Can anyone please tell me how to get the scrollbar element please? Suppose I've already got the scrollbox element. Thanks.
These scrollbox and scrollbar are generated by the richlistbox internally, the scrollbar has no id, no class attribute, nothing.

Are you compiling a version of Firefox or are you trying to make an extension?

Acually I'm trying to compiling Thunderbird. But I think this is a general xul question, so I posted it here.

Scroll bars on richlists should be dynamic by default.
Tip of the day: If it has "toolbar" in the name, it's crap.
