/**
*
* 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.
