title: Custom dock area using Qt 4.4
body: <p>Is it possible to create custom dock areas using Qt 4.4. I know this is possible in Qt 3 as this <a href="http://doc.trolltech.com/4.4/q3dockarea.html#details" rel="noreferrer">document</a> suggests. Excerpt from document"...If you need to create your own dock areas we suggest that you create a subclass of QWidget and add your Q3DockAreas to your subclass...". However, it seems to me that in Qt 4 Q3DockArea has been removed and now the QMainWindow itself has the dock areas. I basically want to have my own dock area widget that I can dock widgets into. This dock area widget can be anywhere in the application. Any ideas on how I can do this?</p>
