This doesn't sound like a problem. Since the text will be a fixed
size, you'll determine that size (won't you?) in pixels and therefore
you'll know exactly how tall a windowpane-sized chunk will be. You
know the height of the text block, you know the height of the
windowpane in which the text block is scrolling, and you know which
chunk of the textblock you're currently showing. When the
currentChunk * (windowpaneHeight + 1) >= textHeight then you can't
scroll any more.
If this model doesn't fit your situation, then perhaps you could give
us a look at a demo page that truly illustrates your dilemma.
Regards,
Paul
