# Wrapper box for TikZ picture [closed]

I am trying to wrap a tikzpicture node inside a box, so that I can refer to this "bounding box" from inside the picture for positioning the nodes relative to that box. I am looking for a command similar to the following one (in this example only "My Node B" is placed on top of the current page):

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage{tikz}

\begin{document}

\begin{frame}
\frametitle{Test Frame}
\makebox[\textwidth]{  % %%% any alternative?
\begin{tikzpicture}[overlay, remember picture]
\draw (current bounding box.north) node (__node_ref)
[anchor=north,fill=gray]
{My node A};
\end{tikzpicture}
}

\begin{tikzpicture}[overlay, remember picture]
\draw (current page.north) node (__node_ref)
[anchor=north,fill=gray]
{My node B};
\end{tikzpicture}

\end{frame}

\end{document}


This way, I can resize the external box and keep the relative position of the nodes of the tikzpicture intact. I tried using \makebox, \framebox and \pfgbox (the latter from inside the {tikzpicture}), but none of them worked.

I know that normally "current bounding box" might work, but I am doing this within Beamer+XeLaTeX and I can only access to the node "current page", so that I have to use "shift" for centering the nodes again.

Any ideas?

• The current bounding box doesn't work because you've added the overlay option to the first node, which produces a bounding box of "zero dimension". Does your first tikzpicture have to be absolutely positioned? – Herr K. Jan 9 '14 at 0:32
• I would like to add it inside a "box" (like in the example) and let beamer choose the position for the box in accordance with the current slide layout. I would like to specify the width and height of the box, but as I said before, I would also like beamer to position the box automatically. – Ricardo Jan 9 '14 at 0:43
• @Ricardo: Then you can remove the overlay option and just use the current bounding box of the node in the first picture. – Herr K. Jan 9 '14 at 1:26
• @Ricardo Solved the comment of Herr K the question? If yes you or HerrK could write an answer, which could be accepted. – Bobyandbob Nov 5 '17 at 14:20
