128 // a proportional font. Here is what Georg Baum has to say about it:
130 bibitemWidest() is supposed to find the bibitem with the widest label in the
131 output, because that is needed as an argument of the bibliography
132 environment to dtermine the correct indentation. To be 100% correct we
133 would need the metrics of the font that is used in the output, but usually
134 we don't have access to these.
135 In practice, any proportional font is probably good enough, since we don't
136 need to know the final with, we only need to know the which label is the
138 Unless there is an easy way to get the metrics of the output font I suggest
139 to use a hardcoded font like "Times" or so.
141 It is very important that the result of this function is the same both with
142 and without GUI. After thinking about this it is clear that no LyXFont
143 metrics should be used here, since these come from the gui. If we can't
144 easily get the LaTeX font metrics we should make our own poor mans front
145 metrics replacement, e.g. by hardcoding the metrics of the standard TeX
