/*!
    \class QCoreApplication
    \brief The QCoreApplication class provides an event loop for console Qt
    applications.

    This class is used by non-GUI applications to provide their event
    loop. For non-GUI application that uses Qt, there should be exactly
    one QCoreApplication object. For GUI applications, see
    QApplication.

    QCoreApplication contains the main event loop, where all events
    from the operating system (e.g., timer and network events) and
    other sources are processed and dispatched. It also handles the
    application's initialization and finalization, as well as
    system-wide and application-wide settings.

    \section1 The Event Loop and Event Handling

    The event loop is started with a call to exec(). Long running
    operations can call processEvents() to keep the application
    responsive.

    In general, we recommend that you create a QCoreApplication or a
    QApplication object in your \c main() function as early as
    possible. exec() will not return until the event loop exits; e.g.,
    when quit() is called.

    Several static convenience functions are also provided. The
    QCoreApplication object is available from instance(). Events can
    be sent or posted using sendEvent(), postEvent(), and
    sendPostedEvents(). Pending events can be removed with
    removePostedEvents() or flushed with flush().

    The class provides a quit() slot and an aboutToQuit() signal.

    \section1 Application and Library Paths

    An application has an applicationDirPath() and an
    applicationFilePath(). Library paths (see QLibrary) can be retrieved
    with libraryPaths() and manipulated by setLibraryPaths(), addLibraryPath(),
    and removeLibraryPath().

    \section1 Internationalization and Translations

    Translation files can be added or removed
    using installTranslator() and removeTranslator(). Application
    strings can be translated using translate(). The QObject::tr()
    and QObject::trUtf8() functions are implemented in terms of
    translate().

    \section1 Accessing Command Line Arguments

    The command line arguments which are passed to QCoreApplication's
    constructor should be accessed using the arguments() function.
    Note that some arguments supplied by the user may have been
    processed and removed by QCoreApplication.

    In cases where command line arguments need to be obtained using the
    argv() function, you must convert them from the local string encoding
    using QString::fromLocal8Bit().

    \section1 Locale Settings

    On Unix/Linux Qt is configured to use the system locale settings by
    default. This can cause a conflict when using POSIX functions, for
    instance, when converting between data types such as floats and
    strings, since the notation may differ between locales. To get
    around this problem, call the POSIX function \c{setlocale(LC_NUMERIC,"C")}
    right after initializing QApplication or QCoreApplication to reset
    the locale that is used for number formatting to "C"-locale.

  Sends \a event to \a receiver: \a {receiver}->event(\a event).
  Returns the value that is returned from the receiver's event
  handler. Note that this function is called for all events sent to
  any object in any thread.

  For certain types of events (e.g. mouse and key events),
  the event will be propagated to the receiver's parent and so on up to
  the top-level object if the receiver is not interested in the event
  (i.e., it returns false).

  There are five different ways that events can be processed;
  reimplementing this virtual function is just one of them. All five
  approaches are listed below:
  \list 1
  \i Reimplementing paintEvent(), mousePressEvent() and so
  on. This is the commonest, easiest and least powerful way.

  \i Reimplementing this function. This is very powerful, providing
  complete control; but only one subclass can be active at a time.

  \i Installing an event filter on QCoreApplication::instance(). Such
  an event filter is able to process all events for all widgets, so
  it's just as powerful as reimplementing notify(); furthermore, it's
  possible to have more than one application-global event filter.
  Global event filters even see mouse events for
  \l{QWidget::isEnabled()}{disabled widgets}. Note that application
  event filters are only called for objects that live in the main
  thread.

  \i Reimplementing QObject::event() (as QWidget does). If you do
  this you get Tab key presses, and you get to see the events before
  any widget-specific event filters.

  \i Installing an event filter on the object. Such an event filter gets all
  the events, including Tab and Shift+Tab key press events, as long as they
  do not change the focus widget.

    Returns the translation text for \a sourceText, by querying the

    from the most recently installed file back to the first
    installed file.

    QObject::tr() and QObject::trUtf8() provide this functionality
    more conveniently.

    \a context is typically a class name (e.g., "MyDialog") and \a
    sourceText is either English text or a short identifying text.

    \a disambiguation is an identifying string, for when the same \a
    sourceText is used in different roles within the same context. By
    default, it is null.

    See the \l QTranslator and \l QObject::tr() documentation for
    more information about contexts, disambiguations and comments.

    \a encoding indicates the 8-bit encoding of character strings.

    \a n is used in conjunction with \c %n to support plural forms.
    See QObject::tr() for details.

    If none of the translation files contain a translation for \a
    sourceText in \a context, this function returns a QString
    equivalent of \a sourceText. The encoding of \a sourceText is
    specified by \e encoding; it defaults to CodecForTr.

    This function is not virtual. You can use alternative translation
    techniques by subclassing \l QTranslator.

    \warning This method is reentrant only if all translators are
    installed \e before calling this method. Installing or removing
    translators while performing translations is not supported. Doing
    so will most likely result in crashes or other undesirable
    behavior.

    Usually arguments().at(0) is the program name, arguments().at(1)
    is the first argument, and arguments().last() is the last
    argument. See the note below about Windows.

    Calling this function is slow - you should store the result in a variable
    when parsing the command line.

    \warning On Unix, this list is built from the argc and argv parameters passed
    to the constructor in the main() function. The string-data in argv is
    interpreted using QString::fromLocal8Bit(); hence it is not possible to
    pass, for example, Japanese command line arguments on a system that runs in a
    Latin1 locale. Most modern Unix systems do not have this limitation, as they are
    Unicode-based.

    On NT-based Windows, this limitation does not apply either.
    On Windows, the arguments() are not built from the contents of argv/argc, as
    the content does not support Unicode. Instead, the arguments() are constructed
    from the return value of
    \l{http://msdn2.microsoft.com/en-us/library/ms683156(VS.85).aspx}{GetCommandLine()}.
    As a result of this, the string given by arguments().at(0) might not be
    the program name on Windows, depending on how the application was started.

    For Symbian applications started with \c RApaLsSession::StartApp one can specify
    arguments using \c CApaCommandLine::SetTailEndL function. Such arguments are only
    available via this method; they will not be passed to \c main function. Also note
    that only 8-bit string data set with \c CApaCommandLine::SetTailEndL is supported

    \fn void qAddPostRoutine(QtCleanUpFunction ptr)
    \relates QCoreApplication

    Adds a global routine that will be called from the QApplication
    destructor. This function is normally used to add cleanup routines
    for program-wide functionality.

    The function specified by \a ptr should take no arguments and should
    return nothing. For example:

    \snippet doc/src/snippets/code/src_corelib_kernel_qcoreapplication.cpp 4

    Note that for an application- or module-wide cleanup,
    qAddPostRoutine() is often not suitable. For example, if the
    program is split into dynamically loaded modules, the relevant
    module may be unloaded long before the QApplication destructor is
    called.

    For modules and libraries, using a reference-counted
    initialization manager or Qt's parent-child deletion mechanism may
    be better. Here is an example of a private class that uses the
    parent-child mechanism to call a cleanup function at the right
    time:

    \snippet doc/src/snippets/code/src_corelib_kernel_qcoreapplication.cpp 5

    By selecting the right parent object, this can often be made to
    clean up the module's data at the right moment.

    \macro Q_DECLARE_TR_FUNCTIONS(context)
    \relates QCoreApplication

    The Q_DECLARE_TR_FUNCTIONS() macro declares and implements two
    translation functions, \c tr() and \c trUtf8(), with these
    signatures:

    \snippet doc/src/snippets/code/src_corelib_kernel_qcoreapplication.cpp 6

    This macro is useful if you want to use QObject::tr() or
    QObject::trUtf8() in classes that don't inherit from QObject.

    Q_DECLARE_TR_FUNCTIONS() must appear at the very top of the
    class definition (before the first \c{public:} or \c{protected:}).
    For example:

    \snippet doc/src/snippets/code/src_corelib_kernel_qcoreapplication.cpp 7

    The \a context parameter is normally the class name, but it can
    be any string.
