I'm trying to set up an environment to use for examples in my thesis document. I would like to increase margins, change the line spacing, open with "Example :", and close with $\Box$. Minipage works beautifully except I can't embed tables or figures within my examples.
This is what I have:
\newcounter{examplecounter}
\newenvironment{example}
{
\vspace{1.75em}
\begin{center}
\begin{minipage}[h]{0.85\textwidth}
\setlength{\parindent}{2em}
\refstepcounter{examplecounter}
\begin{oneandahalfspaced}
\noindent
\textbf{Example \arabic{examplecounter}:}
}{
\hspace{-1em}
$\Box$
\end{oneandahalfspaced}
\end{minipage}
\end{center}
\vspace{1.75em}
}
Any suggestions on how to accomplish what I'm looking for?
\newenvironments: Instead of e.g.\begin{center}...\end{center}you can write\center...\endcenter. This has the advantage that if the\end{example}is misplaced you get a proper warning, otherwise the name of most inner environment started with\begin{will be printed, here:! LaTeX Error: \begin{oneandahalfspaced} on input line XX ended by ...and people get confused because the never typed that environment by themselves. – Martin Scharrer Feb 08 '11 at 10:02
