QtopiaDesktop is able to export data from the Qtopia device in the formatssupported by the ExportInterfaces it finds.<p> Writing an input interface plugin is achieved by subclassing thisbase class, reimplementing the pure virtual functions <a href="#exportData">exportData</a>(),<a href="#externalApplicationName">externalApplicationName</a>(), <a href="#palmtopApplicationName">palmtopApplicationName</a>(), <a href="#dataSets">dataSets</a>() and<a href="#exportSettings">exportSettings</a>() and exporting the class with the <tt>Q_EXPORT_PLUGIN</tt>macro. See the <a href="pluginintro.html">Plugins documentation</a> for details.<p> <p> <p>See also <a href="qtopiadesktop.html">Qtopia Desktop Classes</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn>QStringList <a name="dataSets"></a>ExportInterface::dataSets () const<tt> [pure virtual]</tt></h3> <p> Returns a list of the data formats that this export interface canhandle.<p> Qtopia Desktop can export data in the "addressbook", "datebook","todolist" and "categories" formats.<h3 class=fn>bool <a name="exportData"></a>ExportInterface::exportData ( <a href="centerinterface.html">CenterInterface</a> * center, const QValueList<MergeML::Record> & data, const QString & dataSet )<tt> [pure virtual]</tt></h3> <p> This function is called by Qtopia Desktop when the user requests theexport of Qtopia data. It is passed an interface to Qtopia Desktop,<em>center</em>. The name of the export format is passed in <em>dataSet</em>,and the data to be exported is passed in the <em>data</em> value list. Thefunction should export the data in the <em>dataSet</em> format.<p> Returns TRUE if the data is successfully exported; otherwise returnsFALSE.<h3 class=fn><a href="settingswidget.html">SettingsWidget</a> * <a name="exportSettings"></a>ExportInterface::exportSettings ( QWidget * parent )<tt> [pure virtual]</tt></h3> <p> Returns a widget that the user can use to set any options that canaffect the export process. The returned widget will appear in theimport/export tab of the Qtopia Desktop settings dialog, which isalso its <em>parent</em> widget.<p> May return 0 if there are no user-settable options.<h3 class=fn>QString <a name="externalApplicationName"></a>ExportInterface::externalApplicationName () const<tt> [pure virtual]</tt></h3> <p> Returns the name of the application that imports data in theexported format.
