While you're in that area of code, there are two compiler hints that would be good to clean up also:
[DCC Hint] acLFPainter.pas(380): H2269 Overriding virtual method 'TcxACPCPainter.GetStyleID' has lower visibility (protected) than base class 'TcxPCTabsPainter' (public)
[DCC Hint] acLFPainter.pas(381): H2269 Overriding virtual method 'TcxACPCPainter.GetStyleName' has lower visibility (protected) than base class 'TcxPCTabsPainter' (public)
