Aligning tabs with non-equal-width font

[qweeeeee]

Hey all, I have been programming with FLTK for a project, and came across a problem. I am using Fl_Text_Buffer for output, but the font it uses is Helvetica (a non equal-width font). How would I line up tabs that occur in the buffer (or, how would I change the font to an equal-width font)? thanks in advance!

You will probably get better help over on an FLTK forum... I don't know if it is possible to specify the exact pixel-width of a tab in an FLTK text widget. (It could be, I just don't know.)
