Document Classes ⇒ How to define a new float style?

[c0nny]

Hi,

I have a question on defining an own float style (not sure if this is the right place to post it, I'm new here). I want to have a ruled float but with two rules only instead of three (without the upper rule).
I tried to add the following to my preamble but I'm getting errors (Missing \begin{document}. \newcommand\fs@m and Undefined control sequence. ...f\@fs@cfont{\bfseries}\let\@fs@capt\floatc)

this is the definition:

\newcommand\fs@myruled{\def\@fs@cfont{\bfseries}\let\@fs@capt\floatc@ruled
\def\@fs@post{\kern2pt\hrule\relax}%
\def\@fs@mid{\kern2pt\hrule\kern2pt}%
\let\@fs@iftopcapt\iftrue}

How do I have to do it, is the definition simply in the wrong place?

Thanks for any help
Conny

Do not take this detour. Try one of the packages float, floatrow or trivfloat. With the help of these packages defining new floats is much easier.

Thanks,

the floatrow package actually lets me do what I want.

In case somebody wants to know:

\includepackage{floatrow}

\DeclareFloatStyle{MyRuled}{
capposition=top,
midcode=rule,
postcode=lowrule,
heightadjust=all}

\newfloat{sentences}{th}{los}[chapter]
\floatname{sentences}{Example sentences}
\floatsetup[sentences]{style=MyRuled}

\usepackage[hang,small,bf,nooneline]{caption}

Just one more question:
if I define a new rule \DeclareFloatVCode{grayrule}{{\color{gray}\rule\hsize{1pt}}} and use it instead of the regular rule, the caption moves upwards. Why is that and how can I avoid it?

Since I never worked with floatrow, I can't figure out what's going wrong. A minimal working example (MWE) would make working out a solution much easier.
