Document Structure

Document Structure

The document structuring commands are for dividing your document into sections. QDoc supports six kinds of sections: \part, \chapter, \section1, \section2, \section3, and \section4. The \section1..4 commands are the most useful. They correspond to the traditional section, subsection, etc used in outlining.

\part

The \part command is intended for use in a large document, like a book.

In general a document structuring command considers everything that follows it until the first line break as its argument. The argument is rendered as the unit's title. If the title needs to be spanned over several lines, make sure that each line (except the last one) is ended with a backslash.

In total, there are six levels of sections in QDoc: \part, \chapter, \section1, \section2, \section3 and \section4. \section1 to \section4 correspond to the traditional section, subsection, subsubsection and subsubsubsection.

There is a strict ordering of the section units:

For example, a section1 unit can only appear as the top level section or inside a chapter unit. Skipping a section unit, for example from part to section1, is not allowed.

You can begin with either of the three: part, chapter or section1.
