I get this warning when building a class that derives from QAbstractView:
6>c:\dev\niftk_dev\code\gui\mitk\plugins\uk.ac.ucl.cmic.xnat\src\internal\XnatBrowserView.h(69): warning C4250: 'XnatBrowserView' : inherits 'berry::WorkbenchPart::berry::WorkbenchPart::AddPropertyListener' via dominance
6> c:\p\devd\mitk-src\blueberry\bundles\org.blueberry.ui\src\berryWorkbenchPart.h(163) : see declaration of 'berry::WorkbenchPart::AddPropertyListener'
The AddPropertyListener function is defined in two superclasses of QmitkAbstractView. This could probably be resolved by a 'using' declaration.
