I am trying to swap code blocks as animation. But I cannot put verbatim inside \onslide or \visible.

I tried using a savebox, the problem is the second code blockis typesetted below the first one. I want the code blocks to show in same location.

My code:




\begin{Verbatim}[frame=single, fontsize=\fontsize{7pt}{8pt}\selectfont]
class int(object)
 |  int(x[, base]) -> integer
 |  Convert a string or number to an integer, if possible.  A floating point
 |  argument will be truncated towards zero (this does not include a string
 |  representation of a floating point number!)  When converting a string, use
 |  the optional base.  It is an error to supply a base when converting a
 |  non-string.  If base is zero, the proper base is guessed based on the
 |  string content.  If the argument is outside the integer range a
 |  long object will be returned instead.
\begin{Verbatim}[frame=single, fontsize=\fontsize{7pt}{8pt}\selectfont]
class int(object)
 |  int(x[, base]) -> integer

It works with \only<> instead of onslide<>.

Would you be amenable to using Beamer's semiverbatim environment instead of fancyvrb's Verbatim? Beamer and verbatim reportedly don't play nice with each other; see… and – Jubobs Mar 1 '13 at 11:59
You could also use listings with blocks: see my answer to Using \only on a block - beamer. – Claudio Fiandrino Mar 1 '13 at 12:42
@Jubobs semiverbatim cannot be put inside onslide. – ATOzTOA Mar 1 '13 at 13:05
@ATOzTOA Yes, it can. Try \begin{frame} \onslide<2>{ \begin{semiverbatim} jsudfhsdfhsdf \end{semiverbatim} } \end{frame} – Jubobs Mar 1 '13 at 13:10
@Jubobs Sorry, my mistake, it compiles. But, semiverbatim won't keep my newlines, also the second slide will come below the first one... back to my original problem... – ATOzTOA Mar 1 '13 at 13:25
