MSVC C4100: Application: Raw Formal Parameter Warning

Question

The following code generates a C4100 warning when compiling using MSVC. How is this possible? The "application" is explicitly referenced.

class ApplicationInfo : public QObject { Q_OBJECT public: ... static void initialize(QApplication &application); ... ... } void ApplicationInfo::initialize(QApplication &application) { application.setOrganizationName(ApplicationInfo::organizationName()); application.setOrganizationDomain(ApplicationInfo::organizationName()); application.setApplicationName(ApplicationInfo::applicationName()); application.setApplicationVersion(ApplicationInfo::applicationVersion().toString()); } 

Answer 1

Functions called with the application object are static functions, so they do not reference the application object.

 setOrganizationName setOrganizationDomain setApplicationName setApplicationVersion 

All static members of QCoreApplication obtained, of which QApplication . Using the application link only resolves the namespace for these functions, but the object is not actually used.
