Custom Style for Flex Tree Class

Hi Guys,

I'm looking at customising a Flex Tree Class (Flex Builder 2) with the following options:

1. Remove the default grey Arrow disclosureClosed/OpenIcon
2. Set the Root Node text to bold

To remove the icons I am using:

Code:

---

item.setStyle( "folderClosedIcon", null );
item.setStyle( "folderOpenIcon", null );
item.setStyle( "defaultLeafIcon", null );
item.setStyle( "disclosureClosedIcon", null );
item.setStyle( "disclosureOpenIcon", null );

---

However, the default arrows still remain.

I have searched everywhere, however haven't been able to find anything that helps.

Any help would be greatly appreciated!!!

Cheers,

Damian
