Special Content

The document contents commands identify parts of the documentation, parts with a special rendering, conceptual meaning or function.

\quotation

The \quotation and \endquotation commands delimit a long quotation.

The text in the delimited block is surrounded by <blockquote> and </blockquote> in the html output, e.g.:

/ *!
  Although the prospect of a significantly broader market is
  good news for Firstlogic, the notion also posed some
  challenges. Dave Dobson, director of technology for the La
  Crosse, Wisconsin-based company, said:

  \quotation
     As our solutions were being adopted into new
     environments, we saw an escalating need for easier
     integration with a wider range of enterprise
     applications.
  \endquotation
* /

The text in the \quotation block will appear in the generated HTML as:

<blockquote>
  <p>As our solutions were being adopted into new environments,
  we saw an escalating need for easier integration with a wider
  range of enterprise applications.</p>
    </blockquote>

The built-in style sheet for most browsers will render the contents of the <blockquote> tag with left and right indentations. The example above would be rendered as:

As our solutions were being adopted into new environments, we saw an escalating need for easier integration with a wider range of enterprise applications.

But you can redefine the <blockquote> tag in your style.css file.

\footnote

The \footnote and \endfootnote commands delimit a footnote.

The footnote is rendered at the bottom of the page.

Warning: The \footnote and \endfootnote commands have not been implemented. The footnote is rendered as a regular HTML paragraph.

\note

The \note command defines a new paragraph preceded by "Note:" in bold.

\tableofcontents

The \tableofcontents command has been disabled because QDoc now generates a table of contents automatically.

The automatically generated table of contents appears in the upper righthand corner of the page.

\brief

The \brief command introduces a one-sentence description of a class, namespace, header file, property, or variable.

The brief text is used to introduce the documentation of the associated object, and in lists generated using the \generatelist command and the \annotatedlist command.

The \brief command can be used in two significant different ways: One for classes, namespaces and header files, and one for properties and variables.

When the \brief command is used to describe a property or a variable, the brief text must be a sentence fragment starting with "whether" (for a boolean property or variable) or starting with "the" (for any other property or variable).

For example the boolean QWidget::isWindow property:

/ *!
    \property QWidget::isActiveWindow
    \brief Whether this widget's window is the active window

    The active window is the window that contains the widget that
    has keyboard focus.

    When popup windows are visible, this property is \c true
    for both the active window \e and the popup.

    \sa activateWindow(), QApplication::activeWindow()
* /

and the QWidget::geometry property

/ *!
    \property QWidget::geometry
    \brief The geometry of the widget relative to its parent and
    excluding the window frame

    When changing the geometry, the widget, if visible,
    receives a move event (moveEvent()) and/or a resize
    event (resizeEvent()) immediately.

    ...

   \sa frameGeometry(), rect(), ...
* /

QDoc renders this as:

geometry : QRect

This property holds the geometry of the widget relative to its parent and excluding the window frame.

...

Access functions:

  • const QRect & geometry () const
  • void setGeometry ( int x, int y, int w, int h )
  • void setGeometry ( const QRect & )

See also frameGeometry(), rect(), ...

When the \brief command is used to describe a class, we recommend using a complete sentence like this:

The <classname> class is|provides|contains|specifies...

Warning: Do not repeat your detailed description with the same sentence as the brief statement will be the first paragraph of the detailed description.

/ *!
    \class PreviewWindow
    \brief The PreviewWindow class is a custom widget
           displaying the names of its currently set
           window flags in a read-only text editor.

    The PreviewWindow class inherits QWidget. The widget
    displays the names of its window flags set with the
    setWindowFlags() function. It is also provided with a
    QPushButton that closes the window.

    ...

    \sa QWidget

QDoc renders this as:

Detailed Description

Member Function Documentation

PreviewWindow(QWidget *parent = 0)

Constructs a preview window widget with parent.

setWindowFlags(Qt::WindowFlags flags)

Sets the widgets flags using the QWidget::setWindowFlags() function.

Then runs through the available window flags, creating a text that contains the names of the flags that matches the flags parameter, displaying the text in the widgets text editor.

Using \brief in a \namespace:

/ *!
    \namespace Qt

    \brief The Qt namespace contains miscellaneous identifiers
    used throughout the Qt library.
* /

Using \brief in a \headerfile:

/ *!
    \headerfile <QtGlobal>
    \title Global Qt Declarations

    \brief The <QtGlobal> header file provides basic
    declarations and is included by all other Qt headers.

    \sa <QtAlgorithms>
* /

See also \property, \class, \namespace and \headerfile.

\legalese

The \legalese and \endlegalese commands delimit a license agreement.

In the generated HTML, the delimited text is surrounded by a <div class="LegaleseLeft"> and </div> tags.

An example of a license agreement enclosed in \legalese and \endlegalese:

/ *!
  \legalese

      license as above.
      \endlegalese
    * /

It will appear in the generated HTML as:

<div class="LegaleseLeft">
  <p>Copyright 1996 Daniel Dardailler.</p>

      this software for any purpose is hereby granted without fee,

  <p>Modifications Copyright 1999 Matt Koss, under the same
      license as above.</p>
</div>

If the \endlegalese command is omitted, QDoc will process the \legalese command but considers the rest of the documentation page as the license agreement.

Ideally, the license text is located with the licensed code.

Elsewhere, the documentation identified as \legalese command can be accumulated using \generatelist with legalese-command as the argument. This is useful for generating an overview of the license agreements associated with the source code.

\warning

The \warning command prepends "Warning:" to the command's argument, in bold font.
