Removing default icons from Flex Tree control

What’s so cool about Flex framework is the fact that it’s very extensible, which allows me to do almost anything I want with it.

For example, to remove folder/arrow icons from Flex Tree control, which prevents nodes from collapsing and also creates more space for labels, you can add the following in your stylesheet:

defaultLeafIcon: ClassReference(null);
folderClosedIcon: ClassReference(null);
folderOpenIcon: ClassReference(null);
disclosureClosedIcon: ClassReference(null);
disclosureOpenIcon: ClassReference(null);
