+ * OWidgetStack is the answer to the problem of using Opie at different screen
+ * sizes and to have a different behaviour. Most applications use a QWidgetStack
+ * to supply a view on click. And by clicking the (X) you go back but this
+ * behaviour feels strange on bigger screens. It's ok on smaller one because
+ * one can't determine the difference.
+ * This stack reads the default out of the size of the desktop widget but
+ * can be forced to have either the one or the other behaviour.
+ * The first widget added is considered the 'main' widget and its
+ * sizeHint will be taking if in BigScreen  mode.
+ * In small screen mode this widget behaves exactly like a QWidgetStack and in BigScreen
+ * mode it'll use the MainWindow as child of this widget and arranges the others as
+ * hidden top level widgets.
+ *
+ * @version 0.1
+ * @author hOlgAr F.
