+  \class QTabDialog qtabdialog.h
+
+  \brief The QTabDialog class provides a stack of tabbed widgets.
+
+  \ingroup dialogs
+  \mainclass
+
+  A tabbed dialog is one in which several "tab pages" are available.
+  By clicking on a tab page's tab or by pressing the indicated
+  Alt+\e{letter} key combination, the user can select which tab page
+  they want to use.
+
+  QTabDialog provides a tab bar consisting of single row of tabs at
+  the top; each tab has an associated widget which is that tab's
+  tab page. In addition, QTabDialog provides an OK button and the
+  following optional buttons: Apply, Cancel, Defaults and Help.
+
+  The normal way to use QTabDialog is to do the following in the
+  constructor:
+  \list 1
+  \i Create a QTabDialog.
+  \i Create a QWidget for each of the pages in the tab dialog, insert
+  children into it, set up geometry management for it, and use
+  addTab() (or insertTab()) to set up a tab and keyboard accelerator
+  for it.
+  \i Set up the buttons for the tab dialog using setOkButton(),
+  setApplyButton(), setDefaultsButton(), setCancelButton() and
+  setHelpButton().
+  \i Connect to the signals and slots.
+  \endlist
+
+  If you don't call addTab() the page you have created will not be
+  visible. Don't confuse the object name you supply to the
+  QWidget constructor and the tab label you supply to addTab();
+  addTab() takes user-visible name that appears on the widget's tab
+  and may identify an accelerator, whereas the widget name is used
+  primarily for debugging.
+
+  Almost all applications have to connect the applyButtonPressed()
+  signal to something. applyButtonPressed() is emitted when either OK
+  or Apply is clicked, and your slot must copy the dialog's state into
+  the application.
+
+  There are also several other signals which may be useful:
+  \list
+  \i cancelButtonPressed() is emitted when the user clicks Cancel.
+  \i defaultButtonPressed() is emitted when the user clicks Defaults;
+  the slot it is connected to should reset the state of the dialog to
+  the application defaults.
+  \i helpButtonPressed() is emitted when the user clicks Help.
+  \i aboutToShow() is emitted at the start of show(); if there is any
+  chance that the state of the application may change between the
+  creation of the tab dialog and the time show() is called, you must
+  connect this signal to a slot that resets the state of the dialog.
+  \i currentChanged() is emitted when the user selects a page.
+  \endlist
+
+  Each tab is either enabled or disabled at any given time (see
+  setTabEnabled()). If a tab is enabled the tab text is drawn in
+  black and the user can select that tab. If it is disabled the tab
+  is drawn in a different way and the user cannot select that tab.
+  Note that even if a tab is disabled, the page can still be visible;
+  for example, if all of the tabs happen to be disabled.
+
+  You can change a tab's label and iconset using changeTab(). A tab
+  page can be removed with removePage() and shown with showPage(). The
+  current page is given by currentPage().
+
+  QTabDialog does not support tabs on the sides or bottom, nor can
+  you set or retrieve the visible page. If you need more functionality
+  than QTabDialog provides, consider creating a QDialog and using a
+  QTabBar with QTabWidgets.
+
+  Most of the functionality in QTabDialog is provided by a QTabWidget.
