It works by extracting \e {QDoc comments} from + project source files and then formatting these comments as HTML + pages or DITA XML documents. QDoc finds QDoc comments in \c + {.cpp} files and in \c {.qdoc} files. QDoc does not look for QDoc + comments in \c {.h} files. A QDoc comment always begins with an + exclamation mark (\b{!})). For example: + + \code + / *! + \class QObject + \brief The QObject class is the base class of all Qt objects. + + \ingroup objectmodel + + \reentrant + + QObject is the heart of the Qt \l{Object Model}. The + central feature in this model is a very powerful mechanism + for seamless object communication called \l{signals and + slots}. You can connect a signal to a slot with connect() + and destroy the connection with disconnect(). To avoid + never ending notification loops you can temporarily block + signals with blockSignals(). The protected functions + connectNotify() and disconnectNotify() make it possible to + track connections. + + QObjects organize themselves in \l {Object Trees & + Ownership} {object trees}. When you create a QObject with + another object as parent, the object will automatically + add itself to the parent's \c children() list. The parent + takes ownership of the object. It will automatically + delete its children in its destructor. You can look for an + object by name and optionally type using findChild() or + findChildren(). + + Every object has an objectName() and its class name can be + found via the corresponding metaObject() (see + QMetaObject::className()). You can determine whether the + object's class inherits another class in the QObject + inheritance hierarchy by using the \c inherits() function. + + .... + * / + \endcode + + From the QDoc comment above, QDoc generates the HTML page + \l {http://qt-project.org/doc/qt-5.0/qtcore/qobject.html#details} + {QObject Class Reference}. + + This manual explains how to use the QDoc commands in QDoc comments + to embed good documentation in your source files. It also explains + how to make a \l {The QDoc Configuration File} {QDoc configuration + file}, which you will pass to QDoc on the command line. + + \section1 Running QDoc + + The current name of the QDoc program is \c {qdoc}. To run qdoc + from the command line, give it the name of a configuration file: + + \quotation + \c {$ ../../bin/qdoc ./config.qdocconf} + \endquotation + + QDoc recognizes the \c {.qdocconf} suffix as a \l{The QDoc + Configuration File} {QDoc configuration file}. The configuration + file is where you tell QDoc where to find the project source + files, header files, and \c {.qdoc} files. It is also where you + tell QDoc what kind of output to generate (HTML, DITA XML,...), + and where to put the generated documentation. The configuration + file also contains other information for QDoc. + + See \l{The QDoc Configuration File} for instructions on how to + set up a QDoc configuration file. + + \section1 How QDoc works + + QDoc begins by reading the configuration file you specified on the + command line. It stores all the variables from the configuration + file for later use. One of the first variables it uses is \c + {outputformats}. This variable tells QDoc which output generators + it will run. The default value is \e {HTML}, so if you don't set + \c {outputformats} in your configuration file, QDoc will generate + HTML output. That's usually what you will want anyway, but you can + also specify \e {DITAXML} to get DITA XML output instead. + + Next, QDoc uses the values of the + \l {22-qdoc-configuration-generalvariables.html#headerdirs-variable} + {headerdirs} variable and/or the \l + {22-qdoc-configuration-generalvariables.html#headers-variable} + {headers} variable to find and parse all the header files for your + project. QDoc does \e not scan header files for QDoc comments. It + parses the header files to build a master tree of all the items + that should be documented, in other words, the items that QDoc should find + QDoc comments for. + + After parsing all the header files and building the master tree of + items to be documented, QDoc uses the value of the \l + {22-qdoc-configuration-generalvariables.html#sourcedirs-variable} + {sourcedirs} variable and/or the value of the \l + {22-qdoc-configuration-generalvariables.html#sources-variable} + {sources} variable to find and parse all the \c {.cpp} and \c + {.qdoc} files for your project. These are the files QDoc scans for + \e {QDoc comments}. Remember that a QDoc comment begins with + an exclamation mark: \b {/*!} . + + For each QDoc comment it finds, it searches the master tree for + the item where the documentation belongs. Then it interprets the + qdoc commands in the comment and stores the interpreted commands + and the comment text in the tree node for the item. + + Finally, QDoc traverses the master tree. For each node, if the + node has stored documentation, QDoc calls the output generator + specified by the \c {outputformats} variable to format and write + the documentation in the directory specified in the configuration + file in the \l + {22-qdoc-configuration-generalvariables.html#outputdir-variable} + {outputdir} variable. + + \section1 Command Types + + QDoc interprets three types of commands: + + \list + \li \l {Topic Commands} + \li \l {Context Commands} + \li \l {Markup Commands} + \endlist + + Topic commands identify the element you are documenting, for example + a C++ class, function, type, or an extra page of text + that doesn't map to an underlying C++ element. + + Context commands tell QDoc how the element being documented + relates to other documented elements, for example, next and previous page + links, inclusion in page groups, or library modules. Context + commands can also provide information about the documented element + that QDoc can't get from the source files, for example, whether the + element is thread-safe, whether it is an overloaded or reimplemented function, + or whether it has been deprecated. + + Markup commands tell QDoc how text and image elements in the + document should be rendered, or about the document's outline + structure. +*/ + diff --git a/src/tools/qdoc/doc/qdoc-manual-markupcmds.qdoc b/src/tools/qdoc/doc/qdoc-manual-markupcmds.qdoc new file mode 100644 index 0000000000..082d2b44e2 --- /dev/null +++ b/src/tools/qdoc/doc/qdoc-manual-markupcmds.qdoc @@ -0,0 +1,3967 @@ +/**************************************************************************** +** +** Copyright (C) 2013 Digia Plc and/or its subsidiary(-ies). +** Contact: http://www.qt-project.org/legal +** +** This file is part of the documentation of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:FDL$ +** Commercial License Usage +** Licensees holding valid commercial Qt licenses may use this file in +** accordance with the commercial license agreement provided with the +** Software or, alternatively, in accordance with the terms contained in +** a written agreement between you and Digia.

This command is often assigned the alias, + \e {input}, in the QDoc configuration file, for example \e {alias.include + = input}. + + The command is useful when some snippet of commands and text is to + be used in multiple places in the documentation. In that case, + move the snippet into a separate file and use the \\include + command wherever you want to insert the snippet into the + documentation. To prevent QDoc from reading the file as a + stand-alone page of documentation, we recommend that you use the + \c .qdocinc extension for these \e {include} files. + + The command can have either one or two arguments. The first + argument is always a file name. The contents of the file must be + QDoc input, in other words, a sequence of QDoc commands and text, but + without the enclosing QDoc comment \c{/}\c{*!} ... \c{*}\c{/} delimiters. + If you want to include the entire named file, don't use the second + argument. If you want to include only part of the file, see the + \l{2-argument-form}{two argument form} below. Here is an example + of the one argument form: + + \code + / *! + \page corefeatures.html + \title Core Features + + \include examples/signalandslots.qdocinc + \include examples/objectmodel.qdocinc + \include examples/layoutmanagement.qdocinc + * / + \endcode + + QDoc renders this page \l{corefeatures.html} {as shown here}. + + \target 2-argument-form} + \section2 \\include filename snippet-identifier + + It is a waste of time to make a separate \c .qdocinc file for every + QDoc include snippet you want to use in multiple places in the + documentation, especially given that you probably have to put the + copyright/license notice in every one of these files. So if you + have a large number of snippets to be included, you can put them all in a + single file if you want, and surround each one with: + \code + //! [snippet-id1] + + QDoc commands and text... + + //! [snippet-id1] + + //! [snippet-id2] + + More QDoc commands and text... + + //! [snippet-id2] + \endcode + + Then you can use the two-argument form of the command: + + \code + \input examples/signalandslots.qdocinc snippet-id2 + \input examples/objectmodel.qdocinc another-snippet-id + \endcode + + It works as expected. The sequence of QDoc commands and text found + between the two tags with the same name as the second argument is + sent to the QDoc input stream. You can even nest these snippets, + although it's not clear why you would want to do that. + + \target meta-command + \section1 \\meta + + The \\meta command is mainly used for including metadata in DITA + XML files. It is also used when generating HTML output for specifying + the \e maintainer(s) of a C++ class. + + The command has two arguments: the first argument is the name of the + metadata attribute, and the second argument is the + value for the attribute. Each argument should be enclosed in curly + brackets, as shown in this example: + + \code + / *! + \class QWidget + \brief The QWidget class is the base class of all user interface objects. + + \ingroup basicwidgets + + \meta {technology} {User Interface} + \meta {platform} {OS X 10.6} + \meta {platform} {Symbian} + \meta {platform} {MeeGo} + \meta {audience} {user} + \meta {audience} {programmer} + \meta {audience} {designer} + * / + \endcode + + When running QDoc to generate HTML, the example above will have no + effect on the generated output, but if you run QDoc to generate + DITA XML, the example will generate the following: + + \code + + + + + QWidget + the QWidget class is the base class of all user interface objects. + + Qt Development Frameworks + Qt Project + + + Qt Project + + + + + + + Class reference + + Qt Reference Documentation + + + + QtGui + + + + + + + + \endcode + + In the example output, several values have been set using default + values obtained from the QDoc configuration file. See \l + {Generating DITA XML Output} for details. + + \target omit-command + \section1 \\omit + + The \\omit command and the corresponding \\endomit command + delimit parts of the documentation that you want QDoc to skip. For + example: + + \code + / *! + \table + \row + \li Basic Widgets + \li Basic GUI widgets such as buttons, comboboxes + and scrollbars. + + \omit + \row + \li Component Model + \li Interfaces and helper classes for the Qt + Component Model. + \endomit + + \row + \li Database Classes + \li Database related classes, e.g. for SQL databases. + \endtable + * / + \endcode + + QDoc renders this as: + + \raw HTML + + + + + + + + + + + +

Database ClassesDatabase related classes, e.g. for SQL databases.
+ \endraw + + \target raw-command + \section1 \\raw \span {class="newStuff"} {(avoid)} + + The \\raw command and the corresponding + \\endraw command delimit a block of raw mark-up language code. + + \note Avoid using this command if possible, because it generates + DITA XML code that causes problems. If you are trying to generate + special table or list behavior, try to get the behavior you want + using the \l {span-command} {\\span} and \l {div-command} {\\div} + commands in your \l {table-command} {\\table} or \l {list-command} + {\\list}. + + The command takes an argument specifying the code's format. + Currently, the only supported format is HTML. + + The \\raw command is useful if you want some special HTML effects + in your documentation. + + \code + / *! + Qt has some predefined QColor objects. + + \raw HTML + + +

+ Blue(#0000ff), + dark blue(#000080) and + cyan(#00ffff). +

See the \l {Supporting Derived projects} + section. + + The value of a configuration variable can be set using either '=' + or '+='.

Another is improving search functionality by adding + relevant keywords as tags for a certain category of examples. + + The examples for which meta-content is applied to is specified using + one or more filters. Matching examples to filters is done based on + names, with each example name prefixed with a module name and a + slash. Simple wildcard matching is supported; by using \c {*} at the + end it's possible to match multiple examples with a single string. + + Example: + + \code + manifestmeta.filters = highlighted sql webkit global + + manifestmeta.highlighted.names = "QtGui/Analog Clock Window Example" \ + "QtWidgets/Analog Clock Example" + manifestmeta.highlighted.attributes = isHighlighted:true + + manifestmeta.sql.names = "QtSql/*" + manifestmeta.sql.tags = database,sql + + manifestmeta.webkit.names = "QtWebKitExamples/*" + manifestmeta.webkit.tags = webkit + + manifestmeta.global.names = * + manifestmeta.global.tags = qt5 + \endcode + + Above, an \c isHighlighted attribute is added to two examples.

It works by extracting \e {QDoc comments} from - project source files and then formatting these comments as HTML - pages or DITA XML documents. QDoc finds QDoc comments in \c - {.cpp} files and in \c {.qdoc} files. QDoc does not look for QDoc - comments in \c {.h} files. A QDoc comment always begins with an - exclamation mark (\b{!})). For example: - - \code - / *! - \class QObject - \brief The QObject class is the base class of all Qt objects. - - \ingroup objectmodel - - \reentrant - - QObject is the heart of the Qt \l{Object Model}. The - central feature in this model is a very powerful mechanism - for seamless object communication called \l{signals and - slots}. You can connect a signal to a slot with connect() - and destroy the connection with disconnect(). To avoid - never ending notification loops you can temporarily block - signals with blockSignals(). The protected functions - connectNotify() and disconnectNotify() make it possible to - track connections. - - QObjects organize themselves in \l {Object Trees & - Ownership} {object trees}. When you create a QObject with - another object as parent, the object will automatically - add itself to the parent's \c children() list. The parent - takes ownership of the object. It will automatically - delete its children in its destructor. You can look for an - object by name and optionally type using findChild() or - findChildren(). - - Every object has an objectName() and its class name can be - found via the corresponding metaObject() (see - QMetaObject::className()). You can determine whether the - object's class inherits another class in the QObject - inheritance hierarchy by using the \c inherits() function. - - .... - * / - \endcode - - From the QDoc comment above, QDoc generates the HTML page - \l {http://qt-project.org/doc/qt-5.0/qtcore/qobject.html#details} - {QObject Class Reference}. - - This manual explains how to use the QDoc commands in QDoc comments - to embed good documentation in your source files. It also explains - how to make a \l {The QDoc Configuration File} {QDoc configuration - file}, which you will pass to QDoc on the command line. - - \section1 Running QDoc - - The current name of the QDoc program is \c {qdoc}. To run qdoc - from the command line, give it the name of a configuration file: - - \quotation - \c {$ ../../bin/qdoc ./config.qdocconf} - \endquotation - - QDoc recognizes the \c {.qdocconf} suffix as a \l{The QDoc - Configuration File} {QDoc configuration file}. The configuration - file is where you tell QDoc where to find the project source - files, header files, and \c {.qdoc} files. It is also where you - tell QDoc what kind of output to generate (HTML, DITA XML,...), - and where to put the generated documentation. The configuration - file also contains other information for QDoc. - - See \l{The QDoc Configuration File} for instructions on how to - set up a QDoc configuration file. - - \section1 How QDoc works - - QDoc begins by reading the configuration file you specified on the - command line. It stores all the variables from the configuration - file for later use. One of the first variables it uses is \c - {outputformats}. This variable tells QDoc which output generators - it will run. The default value is \e {HTML}, so if you don't set - \c {outputformats} in your configuration file, QDoc will generate - HTML output. That's usually what you will want anyway, but you can - also specify \e {DITAXML} to get DITA XML output instead. - - Next, QDoc uses the values of the - \l {22-qdoc-configuration-generalvariables.html#headerdirs-variable} - {headerdirs} variable and/or the \l - {22-qdoc-configuration-generalvariables.html#headers-variable} - {headers} variable to find and parse all the header files for your - project. QDoc does \e not scan header files for QDoc comments. It - parses the header files to build a master tree of all the items - that should be documented, in other words, the items that QDoc should find - QDoc comments for. - - After parsing all the header files and building the master tree of - items to be documented, QDoc uses the value of the \l - {22-qdoc-configuration-generalvariables.html#sourcedirs-variable} - {sourcedirs} variable and/or the value of the \l - {22-qdoc-configuration-generalvariables.html#sources-variable} - {sources} variable to find and parse all the \c {.cpp} and \c - {.qdoc} files for your project. These are the files QDoc scans for - \e {QDoc comments}. Remember that a QDoc comment begins with - an exclamation mark: \b {/*!} . - - For each QDoc comment it finds, it searches the master tree for - the item where the documentation belongs. Then it interprets the - qdoc commands in the comment and stores the interpreted commands - and the comment text in the tree node for the item. - - Finally, QDoc traverses the master tree. For each node, if the - node has stored documentation, QDoc calls the output generator - specified by the \c {outputformats} variable to format and write - the documentation in the directory specified in the configuration - file in the \l - {22-qdoc-configuration-generalvariables.html#outputdir-variable} - {outputdir} variable. - - \section1 Command Types - - QDoc interprets three types of commands: - - \list - \li \l {Topic Commands} - \li \l {Context Commands} - \li \l {Markup Commands} - \endlist - - Topic commands identify the element you are documenting, for example - a C++ class, function, type, or an extra page of text - that doesn't map to an underlying C++ element. - - Context commands tell QDoc how the element being documented - relates to other documented elements, for example, next and previous page - links, inclusion in page groups, or library modules. Context - commands can also provide information about the documented element - that QDoc can't get from the source files, for example, whether the - element is thread-safe, whether it is an overloaded or reimplemented function, - or whether it has been deprecated. - - Markup commands tell QDoc how text and image elements in the - document should be rendered, or about the document's outline - structure. -*/ - -/*! - \page 03-qdoc-commands-markup.html -

The command's general syntax is: - - \code - \l {link target} {link text} - \endcode - - \code - / *! - Read the \l {http://qt-project.org/doc/qt-5.0/} - {Qt 5.0 Documentation} carefully. - * / - \endcode - - QDoc renders this as: - - \quotation - Read the \l {http://qt-project.org/doc/qt-5.0/} - {Qt 5.0 Documentation} carefully. - \endquotation - - If the link target is equivalent to the link text, the second - argument can be omitted. - - For example, if you have documentation like: - - \code - / *! - \target assertions - - Assertions make some statement about the text at the - point where they occur in the regexp, but they do not - match any characters. - - ... - - Regexps are built up from expressions, quantifiers, and - \l {assertions} {assertions}. - * / - \endcode - - You can simplify this as follows: - - \code - / *! - \target assertions - - Assertions make some statement about the text at the - point where they occur in the regexp, but they do not - match any characters. - - ... - - Regexps are built up from expressions, quantifiers, and - \l assertions. - * / - \endcode - - For the one-parameter version, the braces can often be omitted. - The \\l command supports several kinds of links: - - \list - - \li \c {\l QWidget} - The name of a class documented with the \l - {class-command} {\\class} command. - - \li \c {\l QWidget::sizeHint()} - The name of a member function, - documented with or without an \l {fn-command} {\\fn} command. - - \li \c {\l } - The subject of a \l {headerfile-command} - {\\headerfile} command. - - \li \c {\l widgets/wiggly} - The relative path used in an \l - {example-command} {\\example} command. - - \li \c {\l {QWidget Class Reference}} - The title used in a - \l {title-command} {\\title} command. - - \li \c {\l {Introduction to QDoc}}- The text from one of the - \l{part-command} {\\part}, \l{chapter} {\\chapter}, or \l - {sectionOne-command} {\\section} commands. - - \li \c {\l fontmatching} - The argument of a \l {target-command} - {\\target} command. - - \li \c {\l {Shared Classes}} - A keyword named in a \l - {keyword-command} {\\keyword} command. - - \li \c {\l network.html} - The file name used in a \l - {page-command} {\\page} command. - - \li \c {\l http://qt-project.org/} - A URL. - - \endlist - - QDoc also tries to make a link out of any word that doesn't - resemble a normal English word, for example, Qt class names or - functions, like QWidget or QWidget::sizeHint(). In these cases, - the \\l command can actually be omitted, but by using the command, - you ensure that QDoc will emit a warning if it cannot find the - link target.

If the line ends with a comma, you can continue - the list on the next line. The general syntax is: - - \code - \sa {the first link}, {the second link}, - {the third link}, ... - \endcode - - QDoc will automatically try to generate "See also" links - interconnecting a property's various functions. For example, a - setVisible() function will automatically get a link to visible() - and vice versa. - - In general, QDoc will generate "See also" links that interconnect - the functions that access the same property. It recognizes four - different syntax versions: - - \list - \li \c property() - \li \c setProperty() - \li \c isProperty() - \li \c hasProperty() - \endlist - - The \\sa command supports the same kind of links as the \l - {l-command} {\\l} command. - - \code - / *! - Appends the actions \a actions to this widget's - list of actions. - - \sa removeAction(), QMenu, addAction() - * / - void QWidget::addActions(QList actions) - { - ... - } - \endcode - - QDoc renders this as: - - \quotation - \b {void QWidget::addActions ( QList - \e actions )} - - Appends the actions \e actions to this widget's list of - actions. - - See also \l {QWidget::removeAction()} {removeAction()}, - \l QMenu, and \l {QWidget::addAction()} {addAction()}. - \endquotation - - See also \l {l-command} {\\l}, \l {target-command} {\\target} and - \l {keyword-command} {\\keyword}. - - - \target target-command - \section1 \\target - - The \\target command names a place in the documentation that you - can link to using the \l {l-command} {\\l (link)} and \l - {sa-command} {\\sa (see also)} commands. - - The text up to the line break becomes the target name.

This command is often assigned the alias, - \e {input}, in the QDoc configuration file, for example \e {alias.include - = input}. - - The command is useful when some snippet of commands and text is to - be used in multiple places in the documentation. In that case, - move the snippet into a separate file and use the \\include - command wherever you want to insert the snippet into the - documentation. To prevent QDoc from reading the file as a - stand-alone page of documentation, we recommend that you use the - \c .qdocinc extension for these \e {include} files. - - The command can have either one or two arguments. The first - argument is always a file name. The contents of the file must be - QDoc input, in other words, a sequence of QDoc commands and text, but - without the enclosing QDoc comment \c{/}\c{*!} ... \c{*}\c{/} delimiters. - If you want to include the entire named file, don't use the second - argument. If you want to include only part of the file, see the - \l{2-argument-form}{two argument form} below. Here is an example - of the one argument form: - - \code - / *! - \page corefeatures.html - \title Core Features - - \include examples/signalandslots.qdocinc - \include examples/objectmodel.qdocinc - \include examples/layoutmanagement.qdocinc - * / - \endcode - - Here are links to the \c .qdocinc files used above: - \l{signalandslots.qdocinc}, \l{objectmodel.qdocinc}, - \l{layoutmanagement.qdocinc}. QDoc renders this page - \l{corefeatures.html} {as shown here}. - - \target 2-argument-form} - \section2 \\include filename snippet-identifier - - It is a waste of time to make a separate \c .qdocinc file for every - QDoc include snippet you want to use in multiple places in the - documentation, especially given that you probably have to put the - copyright/license notice in every one of these files. So if you - have a large number of snippets to be included, you can put them all in a - single file if you want, and surround each one with: - \code - //! [snippet-id1] - - QDoc commands and text... - - //! [snippet-id1] - - //! [snippet-id2] - - More QDoc commands and text... - - //! [snippet-id2] - \endcode - - Then you can use the two-argument form of the command: - - \code - \input examples/signalandslots.qdocinc snippet-id2 - \input examples/objectmodel.qdocinc another-snippet-id - \endcode - - It works as expected. The sequence of QDoc commands and text found - between the two tags with the same name as the second argument is - sent to the QDoc input stream. You can even nest these snippets, - although it's not clear why you would want to do that. - - \target meta-command - \section1 \\meta - - The \\meta command is mainly used for including metadata in DITA - XML files. It is also used when generating HTML output for specifying - the \e maintainer(s) of a C++ class. - - The command has two arguments: the first argument is the name of the - metadata attribute, and the second argument is the - value for the attribute. Each argument should be enclosed in curly - brackets, as shown in this example: - - \code - / *! - \class QWidget - \brief The QWidget class is the base class of all user interface objects. - - \ingroup basicwidgets - - \meta {technology} {User Interface} - \meta {platform} {OS X 10.6} - \meta {platform} {Symbian} - \meta {platform} {MeeGo} - \meta {audience} {user} - \meta {audience} {programmer} - \meta {audience} {designer} - * / - \endcode - - When running QDoc to generate HTML, the example above will have no - effect on the generated output, but if you run QDoc to generate - DITA XML, the example will generate the following: - - \code - - - - - QWidget - the QWidget class is the base class of all user interface objects. - - Qt Development Frameworks - Qt Project - - - Qt Project - - - - - - - Class reference - - Qt Reference Documentation - - - - QtGui - - - - - - - - \endcode - - In the example output, several values have been set using default - values obtained from the QDoc configuration file.

How these DITA maps will be used automatically or manually by the - documentation build process is still under consideration. This section will be updated - as the decisions are made. - - \section1 What is a DITA map? - - A complete description of DITA can be found at the - \l{http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=dita} - {OASIS Darwin Information Typing Architecture} site. - - An explanation of the DITA map is found at that site - \l{http://docs.oasis-open.org/dita/v1.2/os/spec/langref/map.html}{here}. - - \target ditamap-command - \section1 \\ditamap - - The \\ditamap command is for creating a DITA map using qdoc commands. - The \\ditamap command is a kind of \\page command that produces a - \e{.ditamap} instead of a \e{.html} or \e{.xml} file. The file that - is created actually contains XML text, but the \e{.ditamap} suffix is - used to identify the file as containing a DITA MAP. - - The argument is the name of the file to be created. In the following - example, the file \e{creator.ditamap} is output: - \code - \ditamap creator.ditamap - \endcode - - \target topicref-command - \section1 \\topicref \\endtopicref - - The \\topicref \\endtopicref commands are for creating a topicref - in the ditamap. The \\endtopicref command is required because - \\topicref commands can be nested. - - \\topicref has two arguments. The first argument becomes the value - of the \e navtitle attribute. Normally, you use the title of the - topic being referenced. This title is often what will appear in a - table of contents constructed from the ditamap. - - The second argument is the name of the page being referenced. The - second argument is actually optional, for example if you are using - a topicref as a container for other topicrefs and maprefs. It is - also optional if you want qdoc to find the page name for you by - looking up the title in its internal data structure. It is recommended - that you provide the second parameter if you know the page name. - - \code - \topicref {QML Module QtQuick 2} {qtquick-2.xml} - \mapref {Creator Manual} {creator-manual.ditamap} \endmapref - \topicref {QML Mouse Events} {qtquick2-mouseevents.xml} \endtopicref - \topicref {Property Binding} {qtquick2-propertybinding.xml} \endtopicref - \endtopicref - \endcode - - \target mapref-command - \section1 \\mapref - - The \\mapref command is for creating a mapref in the ditamap. A - mapref refers to another ditamap, which you want to include in - your ditamap. Like the \\topicref command, the \\mapref command - has two arguments, but for the \\mapref command, both arguments - are required. The arguments are essentially the same as described - for \\topicref, but for \\mapref, the second command must be the - name of another ditamap, i.e. it must have the \e{.ditamap} - suffix. You must provide the file name. qdoc can't look up the - file name for you. - - \code - \mapref {Creator Manual} {creator-manual.ditamap} \endmapref - \endcode - - \section1 An example ditamap page - - The following example uses the three qdoc ditamap commands described above. - - \code - \ditamap creator.ditamap - \title The DITA Map for Creator - - \topicref {QML Module QtQuick 1} - \topicref {QML Mouse Events} \endtopicref - \topicref {Property Binding} \endtopicref - \endtopicref - - \topicref {QML Module QtQuick 2} {qtquick-2.xml} - \mapref {Creator Manual} {creator-manual.ditamap} \endmapref - \topicref {QML Mouse Events} {qtquick2-mouseevents.xml} \endtopicref - \topicref {Property Binding} {qtquick2-propertybinding.xml} \endtopicref - \endtopicref - - \topicref {QML Module QtQuick.Particles 2} {qtquick-particles-2.xml} - \topicref {Age} {qml-qtquick-particles2-age.xml} \endtopicref - \endtopicref - \endcode - - \section1 The resulting ditamap file - - This is the \e{.ditamap} file you get when you input the qdoc - ditamap page shown above.

The pathname to your configuration file is passed to - QDoc on the command line: - - \quotation - \c {/current/dir$ ../../bin/qdoc ./config.qdocconf} - \endquotation - - \section1 General Description - - The configuration file is a list of entries of the form \e - {"variable = value"}. Using the configuration variables, you can - define where QDoc should find the various source files, images and - examples, where to put generated documentation etc. The - configuration file can also contain directives like \c - include. For an example, see the \l minimum.qdocconf file. - - You can also use configuration variables to get QDoc to support - \l{Supporting Derived Projects} {derived projects}, i.e QDoc can - generate links in your project's documentation to elements in the - Qt online documentation. See the \l {Supporting Derived projects} - section. - - The value of a configuration variable can be set using either '=' - or '+='. The difference is that '=' overrides the previous value, - while '+=' adds a new value to the current one. - - Some configuration variables accept a list of strings as their - value, for example: - \l {22-qdoc-configuration-generalvariables.html#sourcedirs-variable} - {\c{sourcedirs}}, while others accept only a single string. Double - quotes around a value string are optional, but including them allows - you to use special characters like '=' and ' \" ' within the value - string, for example: - - \code - HTML.postheader = "Home" - \endcode - - If an entry spans many lines, use a backslash at the end of every - line but the last: - - \code - sourcedirs = kernel \ - tools \ - widgets - \endcode - - \section1 Configuration Variables - - \section1 Variable List - - \list - \li \l {22-qdoc-configuration-generalvariables.html#alias-variable} {alias} - \li \l {23-qdoc-configuration-cppvariables.html#Cpp.ignoredirectives-variable} {Cpp.ignoredirectives} - \li \l {23-qdoc-configuration-cppvariables.html#Cpp.ignoretokens-variable} {Cpp.ignoretokens} - \li \l {22-qdoc-configuration-generalvariables.html#defines-variable} {defines} - \li \l {22-qdoc-configuration-generalvariables.html#edition-variable} {edition} - \li \l {22-qdoc-configuration-generalvariables.html#exampledirs-variable} {exampledirs} - \li \l {22-qdoc-configuration-generalvariables.html#examples-variable} {examples} - \li \l {22-qdoc-configuration-generalvariables.html#examples.fileextensions-variable} {examples.fileextensions} - \li \l {22-qdoc-configuration-generalvariables.html#excludedirs-variable} {excludedirs} - \li \l {22-qdoc-configuration-generalvariables.html#excludefiles-variable} {excludefiles} - \li \l {22-qdoc-configuration-generalvariables.html#extraimages-variable} {extraimages} - \li \l {22-qdoc-configuration-generalvariables.html#falsehoods-variable} {falsehoods} - \li \l {22-qdoc-configuration-generalvariables.html#headerdirs-variable} {headerdirs} - \li \l {22-qdoc-configuration-generalvariables.html#headers-variable} {headers} - \li \l {22-qdoc-configuration-generalvariables.html#headers.fileextensions-variable} {headers.fileextensions} - \li \l {24-qdoc-configuration-htmlvariables.html#HTML.footer-variable} {HTML.footer} - \li \l {24-qdoc-configuration-htmlvariables.html#HTML.postheader-variable} {HTML.postheader} - \li \l {24-qdoc-configuration-htmlvariables.html#HTML.style-variable} {HTML.style} - \li \l {22-qdoc-configuration-generalvariables.html#imagedirs-variable} {imagedirs} - \li \l {22-qdoc-configuration-generalvariables.html#images-variable} {images} - \li \l {22-qdoc-configuration-generalvariables.html#images.fileextensions-variable} {images.fileextensions} - \li \l {22-qdoc-configuration-generalvariables.html#language-variable} {language} - \li \l {22-qdoc-configuration-generalvariables.html#macro-variable} {macro} - \li \l {22-qdoc-configuration-generalvariables.html#manifestmeta-variable} {manifestmeta} - \li \l {22-qdoc-configuration-generalvariables.html#outputdir-variable} {outputdir} - \li \l {22-qdoc-configuration-generalvariables.html#outputformats-variable} {outputformats} - \li \l {22-qdoc-configuration-generalvariables.html#sourcedirs-variable} {sourcedirs} - \li \l {22-qdoc-configuration-generalvariables.html#sources-variable} {sources} - \li \l {22-qdoc-configuration-generalvariables.html#sources.fileextensions-variable} {sources.fileextensions} - \li \l {22-qdoc-configuration-generalvariables.html#spurious-variable} {spurious} - \li \l {22-qdoc-configuration-generalvariables.html#tabsize-variable} {tabsize} - \li \l {22-qdoc-configuration-generalvariables.html#version-variable} {version} - \li \l {22-qdoc-configuration-generalvariables.html#versionsym-variable} {versionsym} - \endlist - - \section1 Categories - - \list - \li \l {Generic Configuration Variables} - \li \l {C++ Specific Configuration Variables} - \li \l {HTML Specific Configuration Variables} - \endlist - - \section1 Configuration File Examples - - \list - \li A minimum configuration file: \l minimum.qdocconf - \li The Qt configuration file: \l qtgui.qdocconf - \endlist -*/ - -/*!

You can also do some minor manipulation of QDoc - itself, controlling its output and processing behavior. - - \target alias-variable - \section1 alias - - The \c alias variable renames a QDoc command. - - The general syntax is \tt {alias.\e{original-command-name} = \e - temporary-command-name}. - - \code - alias.e = i - \endcode - - This renames the built-in command \\e (italics) to be \\i. The \c - alias variable is often used for compatibility reasons. - - See also \l {macro-variable} {macro}. - - \target codeindent-variable - \section1 codeindent - - The \c codeindent variable specifies the level of indentation that - QDoc uses when writing code snippets. - - QDoc originally used a hard-coded value of four spaces for code - indentation to ensure that code snippets could be easily - distinguished from surrounding text. Since we can use \l{HTML - Specific Configuration Variables#HTML.stylesheets} {stylesheets} - to adjust the appearance of certain types of HTML elements, this - level of indentation is not always required. - - \target defines-variable - \section1 defines - - The \c defines variable specifies the C++ preprocessor symbols - that QDoc will recognize and respond to. - - When a preprocessor symbol is specified using the \c defines - variable, you can also use the \l {if-command} {\\if} command to - enclose documentation that only will be included if the - preprocessor symbol is defined. - - The values of the variable are regular expressions (see QRegExp - for details). By default, no symbol is defined, meaning that code - protected with #ifdef...#endif will be ignored. - - \code - defines = Q_QDOC \ - QT_.*_SUPPORT \ - QT_.*_LIB \ - QT_COMPAT \ - QT3_SUPPORT \ - Q_WS_.* \ - Q_OS_.* \ - Q_BYTE_ORDER \ - __cplusplus - \endcode - - This ensures that QDoc will process the code that requires these - symbols to be defined. For example: - - \code - #ifdef Q_WS_WIN - HDC getDC() const; - void releaseDC(HDC) const; - #endif - \endcode - - Since the Q_WS_.* regular expression (specified using the \c - defines variable) matches Q_WS_WIN, QDoc will process the code - within #ifdef and #endif in our example. - - You can also define preprocessor symbols manually on the command - line using the -D option. For example: - - \code - currentdirectory$ qdoc -Dconsoleedition qtgui.qdocconf - \endcode - - In this case the -D option ensures that the \c consoleedition - preprocessor symbol is defined when QDoc processes the source - files defined in the qtgui.qdocconf file. - - See also \l {falsehoods-variable} {falsehoods} and \l {if-command} {\\if}. - - \target edition-variable - \section1 edition - - The \c edition variable specifies which modules are included in - each edition of a package, and provides QDoc with information to - provide class lists for each edition. - - This feature is mostly used when providing documentation for Qt - packages. - - The \c edition variable is always used with a particular edition - name to define the modules for that edition: - - \code - edition.Console = QtCore QtNetwork QtSql QtXml - edition.Desktop = QtCore QtGui QtNetwork QtOpenGL QtSql QtXml \ - QtDesigner QtAssistant Qt3Support QAxContainer \ - QAxServer - edition.DesktopLight = QtCore QtGui Qt3SupportLight - \endcode - - In the above examples, the \c Console edition only includes the - contents of four modules.

For example: - - \code - examples.fileextensions += *.qrc - \endcode - - See also \l{headers.fileextensions}. - - \target excludedirs-variable - \section1 excludedirs - - The \c excludedirs variable is for listing directories that should \e{not} - be processed by qdoc, even if the same directories are included by the - \l {sourcedirs-variable} {sourcedirs} or \l {headerdirs-variable} {headerdirs} - variables. - - For example: - - \code - sourcedirs = src/corelib - excludedirs = src/corelib/tmp - \endcode - - When executed, QDoc will exclude the listed directories from - further consideration. Files in these directories will not be - read by qdoc. - - See also \l {excludefiles-variable} {excludefiles}. - - \target excludefiles-variable - \section1 excludefiles - - The \c excludefiles variable allows you to specify individual files - that should \e{not} be processed by qdoc. - - \code - excludefiles += $QT_CORE_SOURCES/../../src/widgets/kernel/qwidget.h \ - $QT_CORE_SOURCES/../../src/widgets/kernel/qwidget.cpp - \endcode - - If you include the above in your qdocconf file for qtbase, there - will be no qwidget.html generated for html and no qwidget.xml - generated for DITA XML. - - See also \l {excludedirs-variable} {excludedirs}. - - \target extraimages-variable - \section1 extraimages - - The \c extraimages variable tells QDoc to incorporate specific - images in the generated documentation. - - QDoc will not recognize images used within HTML (or any other - markup language). If we want the images to be copied from the - directories specified by \l {imagedirs} {\c imagedirs} (the images - in question must be located in these directories) to the output - directory, we must specify the images using the \c extraimages - variable. - - The general syntax is \tt {extraimages.\e{format} = \e image}. The - file extension is optional. - - For example, in \l qtgui.qdocconf we use a couple of images within - the HTML.postheader variable which value is pure HTML. For that - reason, these images are specified using the \c extraimages - variable: - - \code - extraimages.HTML = qt-logo - \endcode - - See also \l images and \l imagedirs. - - \target falsehoods-variable - \section1 falsehoods - - The \c falsehoods variable defines the truth value of specified - preprocessor symbols as false. - - If this variable is not set for a preprocessor symbol, QDoc - assumes its truth value is true. The exception is '0', which value - always is false. - - QDoc will recognize, and is able to evaluate, the following - preprocessor syntax: - - \code - #ifdef NOTYET - ... - #endif - - #if defined (NOTYET) - ... - #end if - \endcode - - However, faced with unknown syntax like - - \code - #if NOTYET - ... - #endif - \endcode - - QDoc will evaluate it as true by default, \e unless the - preprocessor symbol is specified within the \c falsehoods variable - entry: - - \code - falsehoods = NOTYET - \endcode - - See also \l defines. - - \target generateindex-variable - \section1 generateindex - - The \c generateindex variable contains a boolean value that - specifies whether to generate an index file when HTML - documentation is generated. - - By default, an index file is always generated with HTML - documentation, so this variable is typically only used when - disabling this feature (by setting the value to \c false) or when - enabling index generation for the WebXML output (by setting the - value to \c true). - - \target headerdirs-variable - \section1 headerdirs - - The \c headerdirs variable specifies the directories containing - the header files associated with the \c .cpp source files used in - the documentation. - - \code - headerdirs = $QTDIR/src \ - $QTDIR/extensions/activeqt \ - $QTDIR/extensions/motif \ - $QTDIR/tools/designer/src/lib/extension \ - $QTDIR/tools/designer/src/lib/sdk \ - $QTDIR/tools/designer/src/lib/uilib - \endcode - - When executed, the first thing QDoc will do is to read through the - headers specified in the \l {headers} {\c headers} variable, and - the ones located in the directories specified in the \c headerdir - variable (including all subdirectories), building an internal - structure of the classes and their functions. - - Then it will read through the sources specified in the \l - {sources-variable} {\c sources}, and the ones located in the - directories specified in the \l {sourcedirs-variable} {\c - sourcedirs} varible (including all subdirectories), merging the - documentation with the structure it retrieved from the header - files. - - If both the \c headers and \c headerdirs variables are defined, - QDoc will read through both, first \l {headers} {\c headers} then - \c headerdirs. - - In the specified directories, QDoc will only read the files with - the \c fileextensions specified in the \l {headers.fileextensions} - {\c headers.fileextensions} variable.
