/**
 * @class MainWindow mainwindow.h <KParts/MainWindow>
 *
 * @short A KPart-aware main window, whose user interface is described in XML.
 *
 * It implements all internal interfaces in the case of a
 * KMainWindow as host: the builder and servant interface (for menu
 * merging).
 *
 * Inherit your main window from this class
 * and make sure to call @c setXMLFile() and @c setupGUI() before you
 * call @c createGUI() on the KPart.
 *
 * For example:
 * \code
 * setCentralWidget(m_part->widget());
 * setXMLFile(QStringLiteral("appui.rc"));
 * setupGUI(ToolBar | Keys | StatusBar | Save); // Never Create flag here
 * createGUI(m_part);
 * \endcode
 *
 * @warning You should not pass the @c Default flag set to @c setupGUI(),
 * since it contains the @c Create flag, which is not supposed to be used
 * from this class.
 * @see KXmlGuiWindow::Create, @see setupGUI, @see createGUI
