User-Agent: Mutt/1.4i

Hello Herbert,

I needed to adjust globally the \labelwidth in the LyXlist environment
however the commands such as

  \setlength\labelwidth{<value>} 
  \setlength\labelsep{<value>} 

do not work as one may expect. Moreover the list looks so ugly if the
width of some label exceeds the width of (default) 00.00.0000 string.

I did some fiddling around but wasn't successful so I tried to find the
solution at www.lyx.org/help. But finally found a way how to force LyX
to do that with NO LaTeX commands in the document e.g.

  \begin{list}{}{<settings>}
    \item bla bla bla
    \item bla bla bla
    \item bla bla bla
    ...
  \end{list}
                                    
So check it out...you just put the following code in the preamble

  % adjust the labelwidth in the LyXlist environment
  \newlength\extrawidth
  \setlength\extrawidth{0pt} % default value   

  \renewenvironment{lyxlist}[1]
     {\begin{list}{}
     {\settowidth{\labelwidth}{#1}
      \addtolength{\labelwidth}{\extrawidth}
      \setlength{\leftmargin}{\labelwidth}
      \addtolength{\leftmargin}{\labelsep}
      \renewcommand{\makelabel}[1]{##1\hfil}}}
     {\end{list}}
                                                                                      
If you would like to have the same value of \labelwidth throughout the
whole document set the length of \extrawidth in the preamble  

  \setlength\extrawidth{<value>}

or if you want it to have just for a selected lists in the document you
just type

  \addtolength\extrawidth{<value>}

before the list environment. If needed the \labelwidth may be any time
restored

  \addtolength\extrawidth{-<value>}

  or

  \setlength\extrawidth{0pt}

Of course you can use the

  \settowidth\extrawidth{TEXT}

Anyway the code above doesn't affect the formatting of other lists
(bibliography, etc.).
