Re: [beamer-class] Mixture of \only and \onslide

[Mark Yagnatinsky]

In the future, I suggest you ask such questions at tex.stackexchange.com.  They have wizards far wiser and mightier than I.  I asked your question there and got this simple gem:

\begin{itemize}

\item\alt<1>{Foo}{I replace Foo}

\item\alt<1>{Bar}{I replace Bar}

\item<2> I am new!

\end{itemize}

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

 }

I don't completely agree with the second proposal:

There are two reasons:

- The \only in the first proposal makes the other version completely
invisible, while the above "\item<2>" leaves it dimly visible.

- If I want to have more than two overlays, the nested \alt become
clumsy, while a list of \only sections does not suffer from this.

Unfortunately, I was not allowed to put this comment on StackExchange,
since I do not have enough reputation points there. So I put it here.

Regards,
Jan

I agree that maybe the alt could become clumsy if you have lots of overlays, but if \item<2> is dimly visible for you, then you are not using the default settings.  \item<2> is completely invisible for me.
