+/**
+ * @short %KDE top level main window
+ *
+ * Top level widget that provides toolbars, a status line and a frame.
+ *
+ * It should be used as a top level (parent-less) widget.
+ * It manages the geometry for all its children, including your
+ * main widget.
+ *
+ * Normally, you will inherit from TDEMainWindow,
+ * then construct (or use some existing) widget as
+ * your main view. You can set only one main view.
+ *
+ * You can add as many toolbars as you like. There can be only one menubar
+ * and only one statusbar.
+ *
+ * The toolbars, menubar, and statusbar can be created by the
+ * TDEMainWindow and - unlike the old TDEMainWindow - may, but do not
+ * have to, be deleted by you. TDEMainWindow will handle that internally.
+ *
+ * Height and width can be operated independently from each other. Simply
+ * define the minimum/maximum height/width of your main widget and
+ * TDEMainWindow will take this into account. For fixed size windows set
+ * your main widget to a fixed size.
+ *
+ * Fixed aspect ratios (heightForWidth()) and fixed width widgets are
+ * not supported.
+*
+ * TDEMainWindow will set icon, mini icon and caption, which it gets
+ * from TDEApplication. It provides full session management, and
+ * will save its position, geometry and positions of toolbars and
+ * menubar on logout. If you want to save additional data, reimplement
+ * saveProperties() and (to read them again on next login)
+ * readProperties(). To save special data about your data, reimplement
+ * saveGlobalProperties(). To warn user that application or
+ * windows have unsaved data on close or logout, reimplement
+ * queryClose() and/or queryExit().
+ *
+ * There are also kRestoreMainWindows convenience functions which
+ * can restore all your windows on next login.
+ *
+ * Note that a TDEMainWindow per-default is created with the
+ * WDestructiveClose flag, i.e. it is automatically destroyed when the
+ * window is closed. If you do not want this behavior, specify 0 as
+ * widget flag in the constructor.

+ * @param parent The widget parent. This is usually 0 but it may also be the window

+ *
+ * @param name The object name. For session management and window management to work
+ * properly, all main windows in the application should have a
+ * different name. When passing 0 (the default), TDEMainWindow will create
+ * a unique name, but it's recommended to explicitly pass a window name that will
+ * also describe the type of the window. If there can be several windows of the same
+ * type, append '#' (hash) to the name, and TDEMainWindow will append numbers to make
+ * the names unique. For example, for a mail client which has one main window showing
+ * the mails and folders, and which can also have one or more windows for composing
+ * mails, the name for the folders window should be e.g. "mainwindow" and
+ * for the composer windows "composer#".

+ * If your client has only one kind of toplevel widgets (which
