Beamer and verbatim sync

I'm preparing a beamer presentation to show some basic TikZ stuff. I would like to have a two columns slide, where on the left I have the TikZ figure, and on the right the generating code. BUT, I also want the code to be uncovered set by step, that is, whenever a feature of the figure is uncovered, I want the corresponding piece of code to be uncovered.

Something like:

\begin{frame}[fragile]
\begin{minipage}{0.10\linewidth}
\begin{center}
\begin{tikzpicture}
\draw<1-> (-1.5,0) -- (1.5,0);
\draw<2-> (0,-1.5) -- (0,1.5);
\end{tikzpicture}
\end{center}
\end{minipage}
\begin{minipage}{0.85\linewidth}
\begin{verbatim}
\begin{tikzpicture}
\draw (-1.5,0) -- (1.5,0);
\draw (0,-1.5) -- (0,1.5);
\end{tikzpicture}
\end{verbatim}
\end{minipage}
\end{frame}


The problem is that I couldn't neither manage to use the uncover inside the verbatim nor use the verbatim inside an uncover...

What is the right practice?

Have a look at Herbert's answer to this question. – lockstep May 12 '11 at 18:21

Herbert's answer was helpful! However, for the sake of completeness, here's the correction of the second part of my code from the question:

\begin{minipage}{0.85\linewidth}
\begin{semiverbatim}\small
\uncover<1->{\\begin\{tikzpicture\} }
grid (1.5,1.5);}}
\uncover<2->{  \alert<2>{\\draw (-1.5,0) -- (1.5,0);} }
\uncover<4->{  \alert<4>{\\draw[red,line width=2pt] (0,0) circle (.8cm);}}
rectangle (1,1);}}
parabola (1,1);}}
\uncover<1->{\\end\{tikzpicture\}}
\end{semiverbatim}
\end{minipage}


Thanks you all!

I had the same problem. I did one of the following in my presentation, each solution was used for a different problem (I'm sorry, I don't remember exactly what is used for what)

• I wrapped the tikz figure with \uncover. Note that this is the only case that I did what I think you tried to do.
• I used the \only command which is not recommended.
• I think that I also placed everything inside a single tikz figure but I'm not sure.

Hope this is of any help.
