Document Classes ⇒ Beamer | Fix Overfull \hbox warnings with modified theme

[Fr00pY]

hey everyone,
i have a little problem with beamer and hope that this is the right session in the forum. i modified a theme of beamer in a way that it looks as i like it. everythings works fine and i'm happy with the result but i get some "Overfull \hbox" warnings and would like to know how to fix that without changing the layout.
i know that the way i modified the beamer class might be "horrible", but anyway, i'm here to learn how its done nice and elegant.
thanks in advance!

Hi,

welcome to the board!

Take care of the widths you use, to not exceed the text width.

For example here:

Code: Select all

\begin{beamercolorbox}[wd=1.0429\textwidth,ht=6mm,dp=2mm,leftskip=4mm,
  rightskip=1mm]{box2}%
  \insertframetitle
\end{beamercolorbox}

by wd=1.0429\textwidth it's already too wide for the frame. Furthermore, I would remove the line break \\ after such a box in the template.

i tried that. the problem is, that \textwidth in the headline is as wide as the document, but in the frametitle it seems to be smaller. furthermore if set 1.0429\textwidth to 1\textwidth it doesn't change the warning.
i think the problem is the box containing "X.Y":

Code: Select all

                   \begin{beamercolorbox}[wd=.14\textwidth,ht=6mm,dp=2mm,leftskip=4mm,rightskip=1mm]{box1}%
                         X.Y
                  \end{beamercolorbox}%

if i delete it, the bigger \hbox is gone.

[Stefan Kottwitz]

the problem is, that \textwidth in the headline is as wide as the document, but in the frametitle it seems to be smaller.

Perhaps you mean \paperwidth then, which is larger than \textwidth and means the width of the frame, not of the text area.

\paperwidth works fine, but unfortunately it doesn't removes the main issue. i changed the \setbeamertemplate{frametitle} using \paperwidth:

removing or adding \hspace*{-1cm} results in the \hbox warning. but now the result looks far different from the beginning. how can i move the "X.Y" box to the left, make the frametitle box higher (why is it now smaller anyway...?) and bring it in one line with the "X.Y" box?
