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 -

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.

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. 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 - - - - - - - - - - - -

- \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 - - -

Some topic commands allow you to create documentation - pages that aren't tied to any underlying source code element. - - When QDoc processes a QDoc comment, it tries to connect the - comment to an element in the source code by first looking for a - topic command that names the source code element. If there is no - topic command, QDoc tries to connect the comment to the source - code element that immediately follows the comment.

They allow your project to contain links to the - online Qt documentation, which means that QDoc will be able to - create links to the class reference documentation, without any - explicit linking command. - - \target description-variable - \section1 description - - The description variable holds a short description of the - associated project. - - See also \l project. - - \target indexes-variable - \section1 indexes - - The \c indexes variable lists the index files that will be used to - generate references. - - For example. to make a derived Qt project contain links to the Qt - Reference documentation, you need to specify the associated index - file: - - \code - indexes = $QTDIR/doc/html/qt.index - \endcode - - See also \l project and \l url. - - \target project-variable - \section1 project - - The \c project variable provides a name for the project associated - with the \c .qdocconf file. - - The project's name is used to form a file name for the associated - project's \e index file. - - \code - project = QtCreator - \endcode - - This will cause an index file called \c qtcreator.index to be - created. - - See also \l description and \l indexes. - - \target url-variable - \section1 url - - The \c url variable holds the base URL for the reference - documentation associated with the current project. - - The URL is stored in the generated index file for the - project. When we use the index on its own, QDoc will use this as - the base URL when constructing links to classes, functions, and - other things listed in the index. - - \code - project = Qt - description = Qt Reference Documentation - url = http://qt-project.org/doc/qt-4.8/ - - ... - \endcode - - This makes sure that whenever \c qt.index is used to generate - references to for example Qt classes, the base URL is \c - http://doc.qt.digia.com/4.7. - - See also \l indexes. - - \target howto - \section1 How to Support Derived Projects - - This feature makes use of the comprehensive indexes generated by - QDoc when it creates the Qt reference documentation. - - For example, \l qtgui.qdocconf (the configuration file for Qt) - contains the following variable definitions: - - \code - project = Qt - description = Qt Reference Documentation - url = http://qt-project.org/doc/qt-4.8/ - - ... - \endcode - - The \l project variable name is used to form a file name for the - index file; in this case the \c qt.index file is created. The \l - url is stored in the index file. Afterwards, QDoc will use this - as the base URL when constructing links to classes, functions, - and other things listed in the index. - -*/ - -/*! - \page 26-qdoc-configuration-example-manifest-files.html - \previouspage Supporting Derived Projects - \contentspage QDoc Manual - - \title Example Manifest Files - - QDoc generates XML files that contain information about all documented - examples and demos. These files, named \c {examples-manifest.xml} and - \c {demos-manifest.xml}, are used by Qt Creator to present a list of - examples in its welcome screen and to link to their documentation. - - \section1 Manifest XML Structure - - A manifest file has the following structure: - - \code - - - - - - analog,clock,window - gui/analogclock/main.cpp - - ... - - - \endcode - - Each \c {} element contains information about a name, - description, the location of the project file and documentation, - as well as a list of tags associated with the example. - - \target metacontent - \section1 Manifest Meta Content - - It is possible to augment the manifest files with additional - meta-content - that is, extra attributes and tags for selected - examples, using the \c manifestmeta configuration command. - - One use case for meta-content is highlighting a number of prominent - examples. 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. If - the attribute value is omitted, QDoc uses the string \c {true} by - default. Extra tags are added for Qt WebKit and Qt SQL examples, and - another tag is applied to all examples by using just \c {*} as the - match string. -*/ - -/*! - \page 27-qdoc-commands-alphabetical.html -
