Justin sent me tabstops.doc and I think I have it sorted out now, though
it could be the old "works for me tm" range of software.
Lemme see now, this is a complex format document with two seperate sections
the first line has default tab stops, and the second line has manually
inserted tab stops, On the second line there are 9 tab stops as reported by
both word (click on the line and go to format tabs) and wv. Both wv and word
agree on their placement which includes two insane ones of -1.3 and -1.06
inches, so that bit is working correctly.
The first line does not have any manually inserted tabs, some checking shows
me that the following is how it works.
You have the tabstop array in the PAP which only lists manually inserted
tabstops. If there are none in it, or I assume if you tab after the end
of the last explictly set tab, then you go forword the amount of space that
is listed in the *DOP* structure, ie ps->dop.dxaTab.
There are other goodies in the DOP, including an extra flag whether to
enable or disable widow control throughout the document (something for
the widow code methinks). Which reminds me that the page information is stored
in the SEP, which in theory I suppose (though I have never seen it) means that
the paper size can change inside a document ?
Anyway to get the tabstop sizes in the case of no explictly inserted tabs
I have added the dop to wvParseStruct, and you get the default tab stop
distance in there.
While I am at it, use -DSPRMTEST and read sprmtest to see how to
get a dump of just the sprms to see what ones are actually being
used, it can be handy to isolate the individual problem at hand.
The DOP is different between word versions, but I have only word8
implemented at the moment, this might cause trouble until I get
word 6 and 7's DOP in there correctly, but I have cvs commited these
changes anyway to give you a look.
