Hello!
I'm returning to the problem I reported using equations in the
itemize environment. The use of the amsmath package solves the
problem when using \begin{equation} ... \end{eqnation}, but
doesn't address the problem in the eqnarray environment:
\begin{eqnarray} ... \end{eqnarray} will still have the problem
of the active equation number colour even when inactive, which,
I think, is because this environment is not defined in the
amsmath package.
However, a quick (and elegant I think) fix that solves this
problem and does not require the amsmath package is to redefine
\@eqnnum to exclude \normalcolor from its definition (I feel
silly now that I didn't think of this earlier:-).
\documentclass{powerdot}
\makeatletter
\def\@eqnnum{{\normalfont (\theequation)}}
\makeatother
\begin{document}
\begin{slide}{test}
\begin{itemize}[type=1]
\item 1\pause
\item \onslide*{2}{\color{red}}
\begin{equation}
2
\end{equation}\pause
\item 3
\end{itemize}
\end{slide}
\end{document}
This way, the basic LaTeX equation environments can be used. The
original LaTeX definition of \@eqnnum is
\makeatletter
\def\@eqnnum{{\normalfont \normalcolor (\theequation)}}
\makeatother
which indicates how stupid I was. :-)
So, forget the fix I offered earlier using the \onslide commands,
use this.
Best regards,
Luis Costa
