Which I already did ;)

--
CC_ScrollBar(const QScrollBar *)

 Style_Enabled 	Set if the scrollbar is enabled. 	 Unused. 	  
 Style_HasFocus 	Set if the scrollbar has input focus.

Only those 2 are supported for a CC_ScrollBar. 

There is no Style_MouseOver for PE_ScrollBarXXXX, which is what would be 
needed.
