Re: Getting the text of an item using TCustomRVItemInfo

Reading the source, I've discovered there are several apparent ways to

get the style number:

TCustomRVItemInfo(AllItems[i]).StyleNo

TCustomRVItemInfo(AllItems[i]).AssociatedTextStyleNo

TCustomRVItemInfo(AllItems[i]).GetActualStyleNo

Which of these is most reliable when I'm trying to get the style of the

item? Would they return different values under any circumstances?

I'm still struggling to find a way to get the text. Perhaps I could

explain what I'm actually trying to do here. What I'm creating is a

footnote system, basically, and every time a footnote is inserted, I

need to find the number of the previous footnote so that I can determine

the appropriate number for the new one, and renumber any subsequent

ones. If there's a better way to do this, I'll be very glad to have it

pointed out to me, but at the moment all I can think of is to build an

index of items and move up and down the list, to find which ones have

the footnote style, then read or change their text (= footnote number).

I could store the footnote number in the tag for each item, but I'd

still have to display it in the text, and I'd still have to change it

for all subsequent footnotes, so I still have to be able to write the

text of the item.

All help appreciated,

Martin
