Hi,
I got further ahead. I could solve 2) by using the ntheorem package
instead of amsthm. 1) is partly solved: Adding a "OptionalArgs 1" line to
my style definition enabled the "Insert->Short Title" command in LyX.
However, the optional argument is not written out to LaTeX.
Is there any way to pass an optional argument (in square brackets) from LyX
to the \begin{xxx} of the internally used LaTeX environment?
Thanks
Daniel

Hi,
In my thesis I have to define a couple of terms and I thought about
using the amsthm package which offers the \newtheorem and
\newtheoremstyle commands to generate environments for theorem-like
structures.
So I added to my layout file a new style $Definition to my layout file:
Counter
Name defn
End
Style $Definition
Margin First_Dynamic
LatexType Environment
LatexName defn
LabelSep xx
NextNoIndent 1
ParIndent MMM
ParSkip 0.8
ItemSep 0.2
TopSep 0.5
BottomSep 0.5
ParSep 0.3
Align Block
AlignPossible block, left, center, right
LabelType Counter
LabelCounter defn
LabelString "Definition @[EMAIL PROTECTED]:"
LeftMargin MM
RightMargin MM
LabelFont
Family Sans
Shape Up
Series Bold
Size Small
EndFont
Preamble
\usepackage{amsthm}
\newtheoremstyle{mydefinition}{\topsep}{\topsep}{}{}{\sffamily\bfseries}{:}{1em}{}
\theoremstyle{mydefinition}
\newtheorem{defn}{Definition}[chapter]
EndPreamble
End
All this works fine so far. However, so far I have not been able to
solve two issues, a LyX-related (1.4.5) and a more LaTeX-related:
1) How can I pass the optional title parameter from LyX to the "defn"
environment? The "Insert->Short Title" command I usually use for this
purpose is always disabled (greyed) when I am editing a definition. Is
there a specific flag I can give in the layout definition to enable it?
2) How can I indent the whole thing? The \newtheoremstyle command offers
a parameter for first line indentation, but I would like to indent the
whole thing by, lets say, 2em. Any idea how to achieve that with theorems?
Thanks a lot!
Daniel
