beamer and tikz

[Zarko F. Cucej]

Hi!
Consider the following minimal example:

\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\begin{frame}
\begin{tikzpicture}[
Node/.style = {rectangle, text width=#1, align=flush center}
]\tiny
\node[Node=5ex] {FFT};
\end{tikzpicture}
\end{frame}

\end{document}

It generate the following error:

! Illegal parameter number in definition of \test.
<to be read again>
1
l.11 \end{tikzpicture}

The same example with other documentclass work without above error (as
it is described in manual for TikZ. Do I miss something or this some
bug? I use beamer 3.07.

regards, Zarko

Try to replace this with:

\begin{frame}[fragile]

and make sure your tikzpicture works in an article class or similar
before incorporating it into beamer.

unfortunately, this doesn't help. I receive the same error in beamar.

Any way thank you for your concern.

I don't get the same error. Using your code I get:
1
l.10 \end{tikzpicture}

After adding [fragile] to the frame I get:

l.4 \node[Node=5ex]
{FFT};

Which is a problem with your tikz code.

Hi

I don't know why but you need to define style
outside the frame environment
align=flush center ?? I don't know this style

rectangle ? I think that a text node is a minipage or a parbox
so it's a rectangle

\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\tikzset{Node/.style = { text width=#1, text centered}}
\begin{frame}

\begin{tikzpicture}
\node[Node=5ex] {FFT FTF TTT DGDF};
\end{tikzpicture}
\end{frame}

\end{document}

Dear Alain Matthes,
Thank you for information. This approach is in case of many different
images with different need for parameters quite inconvenient to me. So,
temporary I will stay at direct writing variable parameters in node
options and use styles only for common features.

Yuo get this error if you try to use a parameter number inside the
definition of a command which doesn't have an argument:

\documentclass{article}
\begin{document}
\def\test{\def\abc#1{#1}}
\end{document}

The solution is to double the parameter:

\documentclass{article}
\begin{document}
\def\test{\def\abc##1{blub##1}}

\test \abc{cde}
\end{document}

In the case of beamer doubling is not enough, as the content of a
frame is stored twice: After doubling you get the same error but now
for the command \beamer@doifinframe instead of \test.

So the solution is to redouble the parameter sign:

\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\begin{frame}
\begin{tikzpicture}[
Node/.style = {rectangle, text width=####1}

]\tiny
\node[Node=5ex] {FFT};
\end{tikzpicture}
\end{frame}
\end{document}

Impressive LaTeX knowledge! Thank you for clearing this up.
