<h3>template<class T><br>
class KParts::GenericFactory< T ></h3>
A template for a <a class="el" href="classKParts_1_1Factory.html">KParts::Factory</a> implementation.
<p>
It implements the pure virtual createPartObject method by instantiating the template argument when requested through the className field. In addition it is a container for a part's <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKInstance.html">KInstance</a> object, by providing a static <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKInstance.html">KInstance</a> *instance() method.<p>
The template argument has to inherit from <a class="el" href="classKParts_1_1Part.html">KParts::Part</a> and has to implement two methods: 1) There needs to be a public constructor with the following signature: MyPart( QWidget *parentWidget, const char *widgetName, QObject *parent, const char *name, const QStringList& args )<p>
2) It needs to provide one static method to create a <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKAboutData.html">KAboutData</a> object per request, holding information about the component's name, its authors, license, etc. The signature of that static method has to be <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKAboutData.html">KAboutData</a> *createAboutData()<p>
The template will take care of memory management of the <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKInstance.html">KInstance</a> and the <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKAboutData.html">KAboutData</a> object, meaning ownership of what createAboutData returns is passed to the caller (this template) .<p>
For advanced use you can also inherit from the template and re-implement additionally the virtual <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKInstance.html">KInstance</a> *createInstance() method, for example in case you want to extend the paths of your instance's <a class="elRef" doxygen="kdecore.tag:../../kdecore/html/" href="../../kdecore/html/classKStandardDirs.html">KStandardDirs</a> object.<p>
If a <a class="el" href="classKParts_1_1ReadOnlyPart.html">KParts::ReadOnlyPart</a> is requested through this factory and the template argument implements a <a class="el" href="classKParts_1_1ReadWritePart.html">KParts::ReadWritePart</a> then setReadWrite( false ) will automatically be called in createPartObject.<p>
Use the factory through the K_EXPORT_COMPONENT_FACTORY macro, like that: <div class="fragment"><pre class="fragment"> <span class="keyword">typedef</span> <a class="code" href="classKParts_1_1GenericFactory.html">KParts::GenericFactory</a>&lt;YourKPart&gt; YourKPartFactory;
K_EXPORT_COMPONENT_FACTORY( yourlibrary, YourKPartFactory )
</pre></div> yourlibrary is the library name that you compiled your KPart into.

Reimplement this method in your implementation to create the <a class="el" href="classKParts_1_1Part.html">Part</a>.
<p>
The <a class="elRef" doxygen="qt.tag:" href="qstringlist.html">QStringList</a> can be used to pass additional arguments to the part. If the part needs additional arguments, it should take them as name="value" pairs. This is the way additional arguments will get passed to the part from eg. khtml. You can for example emebed the part into HTML by using the following code: <div class="fragment"><pre class="fragment"> <object type=<span class="stringliteral">"my_mimetype"</span> data=<span class="stringliteral">"url_to_my_data"</span>>
<param name=<span class="stringliteral">"name1"</span> value=<span class="stringliteral">"value1"</span>>
<param name=<span class="stringliteral">"name2"</span> value=<span class="stringliteral">"value2"</span>>
</object>
</pre></div> This could result in a call to <div class="fragment"><pre class="fragment"> <a class="code" href="classKParts_1_1Factory.html#a2">createPart</a>( parentWidget, name, parentObject, parentName, <span class="stringliteral">"Kparts::Part"</span>,
<a class="codeRef" doxygen="qt.tag:" href="qstringlist.html">QStringList</a>(<span class="stringliteral">"name1="</span>value1<span class="stringliteral">""</span>, <span class="stringliteral">"name2="</span>value2<span class="stringliteral">") );</span>
