 /**
  * @class KPageDialog kpagedialog.h KPageDialog
  *
  * @short A dialog base class which can handle multiple pages.
  *
  * This class provides a dialog base class which handles multiple
  * pages and allows the user to switch between these pages in
  * different ways.
  *
  * Currently, @p Auto, @p Plain, @p List, @p Tree and @p Tabbed face
  * types are available (cmp. KPageView).
  *
  * By default a QDialogButtonBox is added to the dialog with two buttons,
  * OK (@c QDialogButtonBox::Ok) and Cancel (@c QDialogButtonBox::Cancel).
  * You can customize which buttons are added to the dialog by using any of the
  * available buttons-related methods.
  *
  * Note that if there is a QDialogButtonBox (either the one added by default, or
  * one you added manually) some logical connections are created:
  * - @c QDialogButtonBox::accepted() is connected to @c QDialog::accept()
  * - @c QDialogButtonBox::rejected() is connected to @c QDialog::reject()
  * this means that you shouldn't create these connections again (otherwise you
  * would end up receiving two duplicate accepted() signals for example).
  *
  * <b>Example:</b>\n
  *
  * @code
  * UrlDialog::UrlDialog( QWidget *parent )
  *   : KPageDialog( parent )
  * {
  *   setFaceType(List);
  *
  *   QLabel *label = new QLabel("Test Page");
  *   addPage(label, i18n("My Test Page"));
  *
  *   label = new QLabel("Second Test Page");
  *   KPageWidgetItem *page = new KPageWidgetItem(label, i18n("My Second Test Page"));
  *   page->setHeader(i18n("My header string"));
  *   page->setIcon(QIcon::fromTheme("file"));
  *
  *   addPage(page);
  *
  *   // Change the buttons added to the dialog
  *   setStandardButtons(QDialogButtonBox::Ok | QDialogButtonBox::Apply | QDialogButtonBox::Cancel);
  *
  *   // Alternatively you can create a QDialogButtonBox, add the buttons you want to it,
  *   // then add that button box to the dialog
  *   QDialogButtonBox *btnBox = new QDialogButtonBox(QDialogButtonBox::Ok | QDialogButtonBox::Apply | QDialogButtonBox::Cancel,
  *                                                   Qt::Horizontal,
  *                                                   this);
  *   setButtonBox(btnBox);
  * }
  * @endcode
