PAP.fWidowControl ??

In word each paragraph has a BRC for the top bottom left and right of it.
the Brc is the Border code which describes any border type like a dashed line
or dotted, or none. And it contains a distance, the dptSpace which is measured
in twips. In feature-examples/supported-paragraph-properties.doc there are
paragraphs with the feature implemented. The html output attempts to retain
this distance using stylesheets so you should be able to see the space in
action with this. There is also brcbetween which is a seperate border code
to be placed between paragraphs which are of the same type as each other
(isPAPConform(PAP *current,PAP *previous)).

yes the wvParseStruct contains a STSH member, this is filled with the details
of all the styles. Look at the header file definition.
There are stsh.Stshi.cstd styles in it, and each style is a STD, whose name
is xstzName (in unicode) and whose CHP and optional PAP are to be found as
union members of the UPE array in each STD. As mentioned much earlier, character
styles have only one upe while paragraph styles have two. character styles don't
fill a chp or pap, but instead fill a chpx, so for the moment I would reccomend
that you avoid using character styles like the plague, but the paragraph styles
are ok. You might need to read stylesheet.c to see how to identify which is
which, and to see what the elements are and what they will contain.
