Re: center the content (text!) of a box

Hi,

This is the best I can get:

\begin{tikzpicture}
 \draw (-0.5,-0.5) rectangle (0.5,0.5);
 \path (0,0) node (c) [text depth=\heightof{$\cdot$}]
 {\phantom{$\mathstrut^2$}$\left(\cdot\right)^2$};
 \draw [red](c.center)  circle (1pt);
\end{tikzpicture}

There may be better solutions, I'm not much of LaTeX user.

Regards

Mark

Hi Mark,

Thanks a lot, the result is much better than before and
should be sufficient.  Just one comment: The option
text depth=\heightof{$\cdot$}  gives an error.
	Missing number, treated as zero.

Best,

Juergen

It works with the current CVS version (compatability with calc for
\heightof was added after 2.0).  You could always try

\newbox\cdotbox
\setbox\cdotbox=\hbox{$\cdot$}
\begin{tikzpicture}
 \draw (-0.5,-0.5) rectangle (0.5,0.5);
 \path (0,0) node (c) [text depth=\ht\cdotbox]
 {\phantom{$\mathstrut^2$}$\left(\cdot\right)^2$};
 \draw [red](c.center) circle (1pt); % is it centered?
\end{tikzpicture}

Which should to the same thing.

Fwd: center the content (text!) of a box

Maybe you can draw the box around the picture:

\begin{tikzpicture}[remember picture,overlay]
  \node (text) at (0, 0) {$\left(\tikz[remember picture] \node[inner sep=0] 
(c) {$\cdot$};\right)^2$};
  \draw (c.center) ++(-0.5, -0.5) rectangle ++(1, 1);
  \draw [red](c.center)  circle (1pt);
\end{tikzpicture}

Re: center the content (text!) of a box

Hi!

try

  \node[text height=0.8em,text depth=0.2em] {$\left(\cdot 
\right)^{2^{2^2}}$};

The problem with your \vphantom is that it is simply "not deep enough"  
because a subscript is not as "low" as the superscript is "high".  
Also, the placement of the subscript is different because no  
paranthesis preceeds it.

Best regards,
Till

Oh, I see. That explains why my seemingly naive attempt 
wasn't successfull.

Thanks,

This works really fine and so I'm going to integrate it into my
library. Thank you!

Interesting, but I will prefer Marks approach.
Thanks for your suggestion.

Best,
