# beamer hooking environment inside frame

is it possible to "hook" an environment inside the beamer frame? I am thinking something like

\newenvironment{iframe}{\begin{frame}[*]{*} \begin{itemize}}{\end{itemize} \end{frame}}


the problem are the two stars---options and frame title propagation. I want to use this sometimes as

\begin{iframe}[shrink=10}{mytitle}
\item my point
\end{iframe}


I need a sort of hook into beginframe and endframe.

regards, /iaw

Edit: The page 62 example gives LaTeX Error: Something's wrong--perhaps a missing \item:

\documentclass{beamer}
\usepackage[english]{babel}  %% necessary for beamer
\newenvironment{itemizeframe}{\begin{frame}\startitemizeframe}{\stopitemizeframe\end{frame}}
\newcommand\startitemizeframe{\begin{bfseries}\begin{itemize}}
\newcommand\stopitemizeframe{\end{itemize}\end{bfseries}}

\begin{document}

\begin{itemizeframe}{Test 1}
\item Hello 1
\end{itemizeframe}

\begin{itemizeframe}[shrink=10]{Test 2}
\item Hello 2
\end{itemizeframe}

\end{document}


don't have enough points to comment, so I need to add this as a clarification of the question itself. yes, indeed, the key problem are the arguments. ideally, I would like itemizeframe to be transparent---same exact behavior as frame, with optional arguments and (optional) title argument. I need to pass my slides onto others, so keeping with the same syntax would be nice.

• Have you had a look at the manual? The end of Section 8.1 (The Frame Environment) on p62--63 seems to cover exactly this example. – Loop Space Dec 23 '13 at 21:36
• Ah, the problem is the arguments. Will you always give the frametitle as you do in your test code, or do you want that handled as beamer does (in that it is actually optional)? – Loop Space Dec 23 '13 at 22:28
• Incidentally, there appear to be two accounts associated with this question. Presumably, they should be merged. If so, you should flag for moderator attention. – Loop Space Dec 23 '13 at 22:30
• @ivoWelch: It looks like you've got two separate accounts, which means you cannot edit your original post or leave comments. The StackExchange staff can merge them together for you. – Werner Dec 24 '13 at 1:49
• Have you looked at how beamer defines the frame environment? Could you not just replicate and modify that? The trouble is partly that you want multiple optional arguments and partly that you want to have some of them specified with {}. The high level LaTeX commands aren't really designed for that kind of thing as far as I know... – cfr Dec 24 '13 at 4:33
