+Now that PDAs get a VGA resolution and Opie runs on Webpads
+and could be used as a Kiosk secure environment the design
+decision that were right for a 320x240/240x320 doesn't necessary
+to be right for bigger screens.
+
+Remember most desktops a few years ago had only a resolution 
+of 800x600.
+Then also to remember is that a webpad with 640x480 is different to
+a PDA with the same resolution. The PDA has a much smaller
+physical display.
+
+With higher resolution the feeling of a desktop comes.
+
+Problems with current Opie:
+    -InputMethod use full width but most of the times are not high enough
+     This actually makes it harder to input and looks stupid.
+    -ToolBars only feels strange on bigger screens. Maybe do it like WinCE3 does
+     share the ToolBar with MenuBar if they're too big for the screen allow handles
+     to either show the left or right side. Note that the handle from Qt looks 
+     bad and should be patched away
+    -The Escape/Close back to View does not make sense on bigger screens and desktop
+     on a desktop you might even want to show multiple views and detach from the 'system'
+     view
+    -Modality. Dunnow how you get back to the enter dialog without modality in Qt/E fix it?
+     On bigger screen this is not the problem you can move windows. But you should try
+     to be less modal in the future.
+     I've added a small to qpeapplication to iterate over the toplevel widgets 99% 
+     ( click on the taskbar to iterate over the widgets first time nothing is changed )
+     , BUT it should be avoided to use modality showMaximized(), exec()
+     INSTEAD we will use a modal helper where one can register to show a dialog for uid
+     type and will get a signal once the settings need to be applied, rejected or discarded.
+     This way you can almost work like with exec(), do not need to care for freeing.
+     Problems sometimes to have more than one dialog in memory is expensive. Allow queueing
+     and reusing this widget ( only set the Record new? )
+    -Viewing on bigger screens you may want to have a seperate viewer widget ( topLevel ) which
+     might also get spon off from the normal operation. The (X) close go back does not make
+     sense on bigger screens and feels strange
+    -Sizing and Auto sizing of widgets
+    
+Widgets and Classes
+
+    Toolbar/Action and Popups:
+	While KParts with XMLGUI provide a fantastic technology to change the GUI
+	on the fly. Parsing these GUI descriptions is not an option for PDAs
+	specially not on start up.
+	Instead we will need to use normal object in this case QAction and QPopupMenuss. We
+	will then group these Actions into groups. Each group can have children and one
+	parent. Each group has two attributes one for the menubar and one for the toolbar.
+	Attributes for each might be | together. Always, Never, Auto are the attributes I 
+	can think of tonite. Always will place this group always there, Never yeah never, 
+	Automatic lets the later described Manager decide. Also one could or MightSpinOff
+	to a group. This way a child group might get spon off if enough place is there.
+	You cann add QAction and QPopupMenus to the group the Group will not take owner ship
+	and you might use your QAction in other places as well.
+	Toplevel groups need to be registered to the manager and this manager will depending
+	on global settings place and control MenuBar and ToolBar/ToolBar.
+	This allows to dynamically create toolbar on the fly
+
+    Modality class:
+	It'll be a template with a QSignal to tell about changes and a method to get to know
+	which action to be applied. It has three template parameters one for the WIdget used
+	and one for the type of uid and the last for the editor widget which
+	at least needs to provide some methods as well.
+	If you need to edit an widget you simply tell the helper about it. If present it'll
+	raise the widget or either queue it or create a new editor depending on a policy
+	one can set manually or get from the system.
+	
+    Viewing:
+	We will provide a special OWidgetStack which either is a real QWidgetStack or a QList
+	of toplevel widgets to be raised. One has to see how one can use it with todolist
+	and datebook. specially the switching back and forth need to be handled but with possible
+	no code reordering ( least intrusive )
+    Viewing II:
+	Example Advanced FM has a tabwidget but on a SIMpad it would make perfect sense to use a
+	QSplitter or QVBox. We will provide an OSplitter which either provides the one
+	or the other widget depending on the size
+	
+	
+These small changes ( replacing Q with O + bit more) should make Opie a better environment for 
+bigger screens. The additional library memory is a fair trade off and memory can be recovered
+by other technics

+ *
+ * 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.
+ * @short Either a true stack or a list of top Level widgets
