Yes. That is how I have been doing it for years.

class GlobalEventFilter : public QObject {
     Q_OBJECT
     typedef QObject BaseClass;
   public:
     GlobalEventFilter( QObject *parent ) : BaseClass(parent) { }
   protected:
     bool eventFilter(QObject*,QEvent*);
};

bool
GlobalEventFilter::eventFilter( QObject *op, QEvent *ep ) {
     if( ep->type() == QEvent::ToolTip && !CommandLineArg::s_DoToolTips )
         return true;    // Filter out.
     return BaseClass::eventFilter(op,ep);
}

...
GlobalEventFilter *mp = new GlobalEventFilter(s_QtApp);
my_qt_app->installEventFilter(mp);
...
