# Example Manifest Files

QDoc generates example-manifest.xml files that contain information about all documented examples. These files are used by Qt Creator to present a list of examples in its welcome screen and to link to their documentation.

## Manifest XML Structure

A manifest file has the following structure:

     <?xml version="1.0" encoding="UTF-8"?>
     <instructionals module="QtGui">
         <examples>
             <example
                 name="Analog Clock Window"
                 docUrl="qthelp://org.qt-project.qtgui.502/qtgui/analogclock.html"
                 projectPath="gui/analogclock/analogclock.pro"
                 imageUrl="qthelp://org.qt-project.qtgui.502/qtgui/images/analogclock-window.png">
                 <description><![CDATA[The Analog Clock Window example shows how
                     to draw the contents of a custom window.]]></description>
                 <tags>analog,clock,window</tags>
                 <fileToOpen>gui/analogclock/main.cpp</fileToOpen>
             </example>
             ...
         </examples>
     </instructionals>

Each `<example>` 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.

## 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 `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 `*` at the end it's possible to match multiple examples with a single string.

Example:

     manifestmeta.filters                = highlighted sql webkit global

     manifestmeta.highlighted.names      = "QtGui/Analog Clock Window" \
                                           "QtWidgets/Analog Clock"
     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            = qt6

Above, an `isHighlighted` attribute is added to two examples. If the attribute value is omitted, QDoc uses the string `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 `*` as the match string.
