/**
 * \brief This class implements the functionality of the window layout, menus,
 *        and signals.
 *
 * This is a reimplementation into C++/Gtkmm of Sodipodi's SPDesktopWidget class.
 * Both SPDesktopWidget and EditWidget adhere to the EditWidgetInterface, so
 * they both can serve as widget for the same SPDesktop/Edit class.
 *
 * Ideally, this class should only contain the handling of the Window (i.e.,
 * content construction and window signals) and implement its
 * EditWidgetInterface.
