    \fn bool QApplication::macEventFilter(EventHandlerCallRef caller, EventRef event)

    \warning This virtual function is only implemented under Mac OS X when against Carbon.

    If you create an application that inherits QApplication and reimplement
    this function, you get direct access to all Carbon Events that Qt registers
    for from Mac OS X with this function being called with the \a caller and
    the \a event.

    Return true if you want to stop the event from being processed.
    Return false for normal event dispatching. The default
    implementation returns false.

    Cocoa uses a different event system which means this function is NOT CALLED
    when building Qt against Cocoa. If you want similar functionality subclass
    NSApplication and reimplement the sendEvent: message to handle all the
    NSEvents. You also will need to to instantiate your custom NSApplication
    before creating a QApplication. See \l
    {http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSApplication_Class/Reference/Reference.html}{Apple's
    NSApplication Reference} for more information.
