menus were (intentionally) missing, and it turns out they were needed. Normally all invocations of INSET_MODIFY should trigger a recordUndo now. Of course all cases have not been tested, but it should be working. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@36770 a592a061-630c-0410-9148-cb99ea01b6c8

// FIXME: this font is used unitialized for now but should be set to

|
|
/*
|
|
bibitemWidest() is supposed to find the bibitem with the widest label in the
|
|
output, because that is needed as an argument of the bibliography
|
|
environment to determine the correct indentation. To be 100% correct we
|
|
would need the metrics of the font that is used in the output, but usually
|
|
we don't have access to these.
|
|
In practice, any proportional font is probably good enough, since we don't
|
|
need to know the final with, we only need to know the which label is the
|
|
widest.
|
|
Unless there is an easy way to get the metrics of the output font I suggest
|
|
to use a hardcoded font like "Times" or so.
|
|
|
|
It is very important that the result of this function is the same both with
|
|
and without GUI. After thinking about this it is clear that no Font
|
|
metrics should be used here, since these come from the gui. If we can't
|
|
easily get the LaTeX font metrics we should make our own poor mans font
|
|
metrics replacement, e.g. by hardcoding the metrics of the standard TeX
|
|
font.
