If Fl_Text_Editor proves to be too complex, try Fl_Multiline_Input
which gives you pretty much the same functionality with no scrollbars.
I would think you can identify the line you're interested in, and
just use strlen() on each keypress to determine if you've gotten
close to the limit you want.. if using a fixed width font, the
number of chars that can fit horizontally and vertically should be
somewhat predictable.
