I have a stack that does this, The Gutenberg Reader, that allows you
to download texts from the Gutenberg web pages and read them in a
book-like layout. You can't change the field size but you can change
the font. It works by putting all the text in a two fields side by
side, and setting the scroll of each field when you go to the next
"page." The scroll of the right-hand field (the "righthand page") is
simply set to the the scroll of the left field + the textHeight*(the
number of lines visible), so it acts like a book. You can download
the standalone at
http://home.comcast.net/~pmbrig/Gutenberg.html
and I can email the original stack to anyone interested.
At some point I will probably tackle the problem of allowing resizing
of the stack and field sizes and/or allowing the user to change the
fontSize/lineHeight, but I kept it relatively simple. Once you get
the scrolling routines set in a couple of handlers (scrollToPageNbr
(), pageNbrToScroll(), etc) it works quite smoothly. The user has no
idea what's happening behind the scenes.
