As you may have deduced, the FXList class uses the stock version of
FXScrollbar (from the C++ library) and doesn't know about any changes
you've made to the Ruby version's initialize() method. However, you
may still be able to get the effect you're after by first constructing
the FXList instance:

    aList = FXList.new(...)

and then accessing its horizontalScrollbar and verticalScrollbar
members to make the desired changes, e.g.

    aList.horizontalScrollbar.borderColor=FXColor::Green
    aList.horizontalScrollbar.hiliteColor=FXColor::Green
    aList.horizontalScrollbar.shadowColor=FXColor::Black
    aList.horizontalScrollbar.backColor=FXColor::Black

I hope this is a typo, but you should be using one of the fox-1.0.x
version libraries with FXRuby-1.0.29. fox-1.2.9 is definitely
incompatible with FXRuby-1.0.29.

Hope this helps,
