Each piece of information isrepresented by a <a href="qmimesource.html">QMimeSource</a> object which can be examined andconverted to concrete data types by functions such as<a href="qimagedrag.html#canDecode">QImageDrag::canDecode</a>() and <a href="qimagedrag.html#decode">QImageDrag::decode</a>().<p> The base QMimeSourceFactory can be used in two ways: as anabstraction of a collection of files or as specifically storeddata. For it to access files, call <a href="#setFilePath">setFilePath</a>() before accessingdata. For stored data, call <a href="#setData">setData</a>() for each item (there arealso convenience functions, e.g. <a href="#setText">setText</a>(), <a href="#setImage">setImage</a>() and<a href="#setPixmap">setPixmap</a>(), that simply call setData() with appropriateparameters).<p> The rich text widgets, <a href="qtextedit.html">QTextEdit</a> and <a href="qtextbrowser.html">QTextBrowser</a>, useQMimeSourceFactory to resolve references such as images or linkswithin rich text documents. They either access the default factory(see <a href="#defaultFactory">defaultFactory</a>()) or their own (see<a href="qtextedit.html#setMimeSourceFactory">QTextEdit::setMimeSourceFactory</a>()). Other classes that arecapable of displaying rich text (such as <a href="qlabel.html">QLabel</a>, <a href="qwhatsthis.html">QWhatsThis</a> or<a href="qmessagebox.html">QMessageBox</a>) always use the default factory.<p> A factory can also be used as a container to store data associatedwith a name. This technique is useful whenever rich text containsimages that are stored in the program itself, not loaded from thehard disk. Your program may, for example, define some image dataas:<pre> static const char* myimage_data[]={ "...", ... "..."}; </pre> <p> To be able to use this image within some rich text, for exampleinside a QLabel, you must create a <a href="qimage.html">QImage</a> from the raw data andinsert it into the factory with a unique name:<pre> QMimeSourceFactory::<a href="#defaultFactory">defaultFactory</a>()->setImage( "myimage", QImage(myimage_data) ); </pre> <p> Now you can create a rich text QLabel with:<pre> <a href="qlabel.html">QLabel</a>* label = new <a href="qlabel.html">QLabel</a>( "Rich text with embedded image:<img source=\"myimage\">" "Isn't that <em>cute</em>?" ); </pre> <p>See also <a href="environment.html">Environment Classes</a> and <a href="io.html">Input/Output and Networking</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="QMimeSourceFactory"></a>QMimeSourceFactory::QMimeSourceFactory ()</h3>Constructs a QMimeSourceFactory that has no file path and nostored content.<h3 class=fn><a name="~QMimeSourceFactory"></a>QMimeSourceFactory::~QMimeSourceFactory ()<tt> [virtual]</tt></h3>Destroys the QMimeSourceFactory, deleting all stored content.<h3 class=fn>void <a name="addFactory"></a>QMimeSourceFactory::addFactory ( <a href="qmimesourcefactory.html">QMimeSourceFactory</a> * f )<tt> [static]</tt></h3>Adds the QMimeSourceFactory <em>f</em> to the list of availablemimesource factories.
