    \typedef QPlatformNativeInterface::EventFilter
    \since 5.0

    A function with the following signature that can be used as an
    event filter:

    \code
    bool myEventFilter(void *message, long *result);
    \endcode

    \sa setEventFilter()
*/

/*!
    \fn EventFilter QPlatformNativeInterface::setEventFilter(const QByteArray &eventType, EventFilter filter)
    \since 5.0

    Replaces the event filter function for the native interface with
    \a filter and returns the pointer to the replaced event filter
    function. Only the current event filter function is called. If you
    want to use both filter functions, save the replaced EventFilter
    in a place where you can call it from.

    The event filter function set here is called for all messages
    received from the platform if they are given type \eventType.
    It is \e not called for messages that are not meant for Qt objects.

    The type of event is specific to the platform plugin chosen at run-time.

    The event filter function should return \c true if the message should
    be filtered, (i.e. stopped). It should return \c false to allow
    processing the message to continue.

    By default, no event filter function is set. For example, this function
    returns a null EventFilter the first time it is called.

    \note The filter function here receives native messages,
    for example, MSG or XEvent structs. It is called by the platform plugin.
