Text Formatting ⇒ beamer, listings | Overlays with Code Listings

[turok]

I have a problem with the following code:

Code: Select all

\documentclass{beamer}
\usepackage{listings}
\begin{document}
\begin{frame}[fragile]
\color<2>[rgb]{1,0,0}{% works
\begin{lstlisting}
COLOR
\end{lstlisting}
}
\only<1>{% don't work
\begin{lstlisting}
ONLY
\end{lstlisting}
}
\end{frame}
\end{document}

Code: Select all

Package Listings Warning: Text dropped after begin of listing on input line 11.

\end{frame}
\end{document}

define the environment before the frame:

Code: Select all

\documentclass{beamer}
\usepackage{listings}
\begin{document}
\defverbatim{\Lst}{%
\begin{lstlisting}
ONLY
\end{lstlisting}}

\begin{frame}[fragile]
\color<2>[rgb]{1,0,0}{% works
\begin{lstlisting}
COLOR
\end{lstlisting}
}
\only<1>{\Lst}% works

\end{frame}
\end{document}
