+ * @short Easy to use widget with many layouts
+ *
+ * Provides a number of ready to use layouts (faces). It is used
+ * as an internal widget in KDialogBase, but can also used as a
+ * widget of its own.
+ *
+ * This class provides KJanusWidget::TreeList, KJanusWidget::IconList,
+ * KJanusWidget::Tabbed, KJanusWidget::Plain and KJanusWidget::Swallow layouts.
+ *
+ * For all modes it is important that you specify the TQWidget::tqminimumSize()
+ * on the page, plain widget or the swallowed widget. If you use a QLayout
+ * on the page, plain widget or the swallowed widget this will be taken care
+ * of automatically. The size is used when the KJanusWidget determines its
+ * own minimum size. You get the minimum size by using the
+ * tqminimumSizeHint() or tqsizeHint() methods.
+ *
+ * Pages that have been added in TreeList, IconList or Tabbed mode can be
+ * removed by simply deleting the page. However, it would be preferable to use
+ * the TQObject::deleteLater() function on the page as the main event loop
+ * may have optimized UI update events of the page by scheduling them for later.
