QtopiaDesktop is able to import data in formats supported by theImportInterfaces it finds into the Qtopia device.<p> Writing an input interface plugin is achieved by subclassing thisbase class, reimplementing the pure virtual functions <a href="#data">data</a>(),<a href="#externalApplicationName">externalApplicationName</a>(), <a href="#palmtopApplicationName">palmtopApplicationName</a>(), <a href="#dataSets">dataSets</a>() and<a href="#importSettings">importSettings</a>() and exporting the class with the <tt>Q_EXPORT_PLUGIN</tt>macro. See the Plugins documentation for details.<p> <p>See also <a href="qtopiadesktop.html">Qtopia Desktop Classes</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn>bool <a name="data"></a>ImportInterface::data ( <a href="centerinterface.html">CenterInterface</a> * center, const QString & dataSet, QValueList<MergeML::Record> & result )<tt> [pure virtual]</tt></h3> <p> This function is called by Qtopia Desktop.
