Servus Markus,

Just an update on what I've been doing on this.

I've solved this part like this:
Tab page class <-> Controller class <-> Window class <-> Struct
{FixedLine, ListBox, RadioBtnUp, RadiobtnDown }

Basically copying the set-up of SfxDocumentInfoDialog, I've tested
this part and it works like a charm!

I've implemented the scroll handler but I haven't tested it yet.

This part was simple, It is basically the same handler as before, only
slightly modifed. For now i put this implementation in the Window
class, but I'm thinking of moving it back were it was before i.e in
the tabpage class. I've tested this as it is now and it works!

Overall I'm still contemplating a bit where to put the code containing
all the the logic behind the dialog. My second attempt here was to
move everything from the tab page class to the window class, but I
this turned out to create more messy code than I had anticipated.

So now I'm opting to keep much of the code intact in the tab page
class. I need to re-wind a bit here, before I have a working patch to
submit.
