Presentations and Posters ⇒ Need a centred headline in Beamer

[ouadad]

I have a classified presentation to put together and I need to specify the classification of each page (UNCLASSIFED, CONFIDENTIAL, SECRET, ETC.) centred at the very top (above the Frametitle) and at the very bottom. I tried using \setbeamertemplate{headline}{UNCLASSIFIED}, for example, but all it does is stick the classification on the far left. When I add it within \begin{center}{}\end{center}, nothing happens. In either case, I get nothing for the footline.

Can someone assist me please?

Code: Select all

\documentclass[t]{beamer}
\begin{document}
\section{Background:  The Problem}
\frame{
\setbeamertemplate{headline}
{
\begin{center}
{\bf UNCLASSIFIED} 
\end{center}
}
\frametitle{Background:  The Problem}
\begin{itemize}
{\small
\item stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff;
\item stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff;
\item stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff;
\item stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff;
\item stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff;
\item stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff stuff;}
\end{itemize}
\setbeamertemplate{footline}
{
\begin{center}{\bf UNCLASSIFIED}
\end{center}
}
}
\end{document}
