Beamer and verbatim sync

Question

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?

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\} }
       \uncover<1->{  \alert<1>{\\draw [step=.2cm,gray!50,thin] (-1.5,-1.5) 
                      grid (1.5,1.5);}}
       \uncover<2->{  \alert<2>{\\draw (-1.5,0) -- (1.5,0);} }
       \uncover<3->{  \alert<3>{\\draw (0,-1.5) -- (0,1.5);}}
       \uncover<4->{  \alert<4>{\\draw[red,line width=2pt] (0,0) circle (.8cm);}}
       \uncover<5->{  \alert<5>{\\draw[green,line width=2pt] (-1,-1) 
                      rectangle (1,1);}}
       \uncover<6->{  \alert<6>{\\draw[blue,line width=2pt] (-.5,-.5) 
                      parabola (1,1);}}
       \uncover<1->{\\end\{tikzpicture\}}
   \end{semiverbatim}
\end{minipage}

Thanks you all!

Answer 2

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.
