Styles to tree component

[advika]

Hi all,

I have given some styles to tree component
for example

menuTree.setStyle("backgroundColor",0x409FDF)
menuTree.setStyle("borderStyle","solid")
menuTree.setStyle("borderColor",0x409FDF)
menuTree.setStyle("themeColor",0xBADEF6)

this is working fine , it as changed the background and border color.

similarly i want to change the scrollbar color of the tree component.

How to change the themeColor of the scrollbar of tree component.

any one please tell me how to do this.

Thanks in advance
