If you are still using just text for each
node in your tree, then, you don’t need to do a custom itemRenderer.
Instead, you can just use a labelFunction. So, on your Tree tag, just add
something like labelFunction=”returnLabel”. Then, you will have a
returnLabel function that looks something like this:
private function returnLabel(item:Object)
: String
{
var str:String [EMAIL PROTECTED] + "
" + [EMAIL PROTECTED];
return str;
}

Subject: [flexcoders] Flex 2 Tree
Behaviour override
Hi,
I am evaluating Flex 2 Beta in comparison with
Laszlo, in order to
make a choice on an RIA framework for our company.
As part of this evaluation I am trying to modify
the Tree control
behaviour, to allow me to display structured text
from more than one
XML attribute in my data source. I have
tried doing this using
ListItemRenderer but it stops displaying all of
the standard tree
behaviour as soon as I override it.
Does anyone know how to do this? Are there
any examples of the tree
bahaviour being overriden?
Below are the sources for the two MXML files.
Thanks,
Yair Iny
