# Beamer: Removing headline and its space on a single frame (for plan), but keeping the footline

There is now 4 hours that I'm Googling to found a solution to my problem but it's still impossible!

Here is the situation: I have some frames in a presentation using the Warsaw theme, on the first one I wanted to remove both headline and footline so I use the \begin{frame}[plain], but I want to, for the next frame, keep the footline but only hide the headline.

I tried the following:

{
\begin{frame}{Sommaire}
\tableofcontents
\end{frame}
}


But, although the content of the headline is removed, it keeps the space blank (as it is used, but not available for my content). So, there is a white space below my frame title... (Table of Contents).

I don't want to have the plan of my presentation in the header here as it is a frame showing the plan ...

Is there anyone here who could help me?

Just to add element to my question (and current research...), when I use the \setbeamertemplate{headline}[default] before the \begin{document}, the "white space" is not here on all the frames. But none of the frames have the headline. And here, I want to keep the headline on all the frames except the ones I choose (table of contents here, as the title page is on plain format).

The reason why using \setbeamertemplate{headline}[default] before \begin{document} works is that the relevant lengths like \headheight, \textheight, ... are calculated once (with \beamer@calculateheadfoot) at the beginning of the document. Anyway, that's a nice solution you found! :-) – diabonas Feb 19 '12 at 15:03
This post is rather old, but in case someone else is facing this problem using beamer. You can use \vskip-20ex to remove spaces just after frame starts as suggested here tex.stackexchange.com/questions/56946/… – bilal Feb 5 '14 at 17:51

Ok, after more investigation (in the beamer sources :)), I have found the solution. For those who will search like me in the future, here it is in a simple small example :

{ % to delimit a block (we only want to remove the header for this frame)
\makeatletter % to change template
\setbeamertemplate{headline}[default] % not mandatory, but I though it was better to set it blank
\def\beamer@entrycode{\vspace*{-\headheight}} % here is the part we are interested in :)
\makeatother
\tableofcontents
\end{frame}
}


It is also possible to define an environment to be able to use it more easily. To do so, use this part of code before the \begin{document} :

\makeatletter
}{}
\makeatother


\begin{withoutheadline}
