Text Measuring Issue

Hi all,

I am using TXNDrawCFStringTextBox to generate a page for printing
(DrawThemeTextBox doesn't print), which works very well for most
purposes. I'm printing out strings from a database, so I have no
page-layout storage; instead this is generated on the fly by
pre-calculating the layout of all the rectangles within the printable
area based on the text's GetThemeTextDimensions.

One problem that I'm facing is when the text dimensions are larger than
what will fit on the page. I need to determine where in a body of text a
rectangle will break the text; then I would need to split the string and
render a new rectangle (on a new page) to handle the rest of the text
(probably by doing a CFStringCreateWithSubstring).

So, all knowledgeable Carbon developers, does anyone know of a method to
determine how much text (character offset, CFRange, lines, etc) fits in
a fixed-size rectangle? A search of the usual headers (Appearance.h,
CFString.h, MacTextEditor.h) aren't giving me the "Aha!" that I'm
longing for.

Thanks in advance,
brian
