Text Formatting ⇒ Avoid figure or page break in a multiple line section title

[rafaelgoes]

Hi there!

The formating rules for thesis in my university demmands that titles (chapters, sections, subsections...) are like:

<number>
<Section title>

-------------------------------------------------------------------
Example:

1.
First Chapter

text text text text text text text text text text text text text text text text text text text text text text text text text text text text

1.1.
First Section

text text text text text text text text text text text text text text text text text text text text text text text text text text text text
----------------------------------------------------------------

I used the following code:

\titleformat{name=\section}
[display]
{\penalty -5000\singlespacing\Large\arial\bfseries}
{\thesection}

The problem is that sometimes I get figures between the section number and the Section Title, such as:

---------------
1.1.
<figure>
First Section

text text text text text text text text text text text text text text text text text text text text text text text text text text text text
----------------

or even section number and section title in separate pages?

----------------
text text text text text text text text text text text text text text text text text text text text text text text text text text text text

1.1.
======== page break =========
First Section
----------------

Does anybody know how to avoid that?

Thanks in advance!

In order to make your question better understandable, provide a minimal working example.
As you already mentioned, your solution doesn't work quite well, but there are better ways. But to think about those, at least the knowledge of the documentclass is needed.

You might also want to take a look at the titlesec-package.

Follow below the MWE:

Code: Select all

\documentclass{book}%
\usepackage{graphicx}
\usepackage{titlesec}

\newcommand{\autolabel}[1]{\label{sec:#1}#1}
\titleformat{name=\chapter}
	[display]
  {\LARGE\bfseries}
  {\thechapter}
  {0pt}
  {\autolabel}

\titleformat{name=\section}% Rafael Goes 25/04/2013
	[display]
  {\penalty -5000\Large\bfseries}
  {\thesection}
  {0pt}
  {\autolabel}

It seems, that this is somehow related to your autolabel-command.
Try this:

Code: Select all

\newcommand{\autolabel}[1]{#1\label{sec:#1}}

Just as a remark, chapters and sections are labeled with the prefix sec:. Be careful, you might get confused when your project is growing.

It worked!
Totally solved the problem!
Thanks a lot!
