Mixture of \only and \onslide behaviour?

[Lukas Barth]

Hi everyone,

I'm having two chunks of \items inside an itemize, and I want to replace the first chunk with the second chunk on click. What I currently do is to wrap both chunks in appropriate \only<>s, like this:

\begin{itemize}

 \only<1> {

  \item Foo

  \item Bar

 }

 \only<2> {

  \item I replace Foo

  \item I replace Bar

  \item I am new!

 }

\end{itemize}

Now, since they are of different sizes, this makes the itemize jump around on the slide. What I would need is some grouping of the \only<>s, that reserves spaces for the contents of the largest \only<> inside the group..

Can something like that be achieved?

Thanks a lot,

Lukas

When I first saw this email, I though to myself, "I know exactly where in the beamer manual to find the answer to this question".  I was about to send an answer along the lines of "see section 9.5", when I decided to double check that things are really as simple as I thought.  Over an hour later, I finally present the following rather simple solution :)

\begin{overprint}

\onslide<1>

\begin{itemize}

\item Foo

\item Bar

\end{itemize}

\onslide<2>

\begin{itemize}

\item I replace Foo

\item I replace Bar

\item I am new!

\end{itemize}

\end{overprint}

Hope this helps.
