/*!
    \class QObject qobject.h
    \brief The QObject class is the base class of all Qt objects.

    \ingroup objectmodel
    \mainclass
    \reentrant

    QObject is the heart of the \link object.html Qt object model.
    \endlink The central feature in this model is a very powerful
    mechanism for seamless object communication called \link
    signalsandslots.html signals and slots \endlink. You can
    connect a signal to a slot with connect() and destroy the
    connection with disconnect(). To avoid never ending notification
    loops you can temporarily block signals with blockSignals(). The
    protected functions connectNotify() and disconnectNotify() make it
    possible to track connections.

    QObjects organize themselves in object trees. When you create a
    QObject with another object as parent, the object will
    automatically do an insertChild() on the parent and thus show up
    in the parent's children() list. The parent takes ownership of the
    object i.e. it will automatically delete its children in its
    destructor. You can look for an object by name and optionally type
    using child() or queryList(), and get the list of tree roots using
    objectTrees().

    Every object has an object name() and can report its className()
    and whether it inherits() another class in the QObject inheritance
    hierarchy.

    When an object is deleted, it emits a destroyed() signal. You can
    catch this signal to avoid dangling references to QObjects. The
    QGuardedPtr class provides an elegant way to use this feature.

    QObjects can receive events through event() and filter the events
    of other objects. See installEventFilter() and eventFilter() for
    details. A convenience handler, childEvent(), can be reimplemented
    to catch child events.

    Last but not least, QObject provides the basic timer support in
    Qt; see QTimer for high-level support for timers.

    Notice that the Q_OBJECT macro is mandatory for any object that
    implements signals, slots or properties. You also need to run the
    \link moc.html moc program (Meta Object Compiler) \endlink on the
    source file. We strongly recommend the use of this macro in \e all
    subclasses of QObject regardless of whether or not they actually
    use signals, slots and properties, since failure to do so may lead
    certain functions to exhibit undefined behaviour.

    All Qt widgets inherit QObject. The convenience function
    isWidgetType() returns whether an object is actually a widget. It
    is much faster than inherits( "QWidget" ).

    Some QObject functions, e.g. children(), objectTrees() and
    queryList() return a QObjectList. A QObjectList is a QPtrList of
    QObjects. QObjectLists support the same operations as QPtrLists
    and have an iterator class, QObjectListIt.

    You can find an object by name (and type) using child(). You can

    future.

    If the object does not have a name, the name() function returns
    "unnamed", so printf() (used in qDebug()) will not be asked to
    output a null pointer. If you want a null pointer to be returned
    for unnamed objects, you can call name( 0 ).

/*!
    Starts a timer and returns a timer identifier, or returns zero if
    it could not start a timer.

    A timer event will occur every \a interval milliseconds until
    killTimer() or killTimers() is called. If \a interval is 0, then
    the timer event occurs once every time there are no more window
    system events to process.

    The virtual timerEvent() function is called with the QTimerEvent
    event parameter class when a timer event occurs. Reimplement this
    function to get timer events.

    If multiple timers are running, the QTimerEvent::timerId() can be
    used to find out which timer was activated.

    Example:
    \code
    class MyObject : public QObject
    {
	Q_OBJECT
    public:
	MyObject( QObject *parent = 0, const char *name = 0 );

    protected:
	void timerEvent( QTimerEvent * );
    };

    MyObject::MyObject( QObject *parent, const char *name )
	: QObject( parent, name )
    {
	startTimer( 50 );    // 50-millisecond timer
	startTimer( 1000 );  // 1-second timer
	startTimer( 60000 ); // 1-minute timer
    }

    void MyObject::timerEvent( QTimerEvent *e )
    {
	qDebug( "timer event, id %d", e->timerId() );
    }
    \endcode

    Note that QTimer's accuracy depends on the underlying operating
    system and hardware. Most platforms support an accuracy of 20 ms;
    some provide more. If Qt is unable to deliver the requested
    number of timer clicks, it will silently discard some.

    The QTimer class provides a high-level programming interface with
    one-shot timers and timer signals instead of events.

    default), all object names match.

    If \a regexpMatch is TRUE (the default), \a objName is a regular
    expression that the objects's names must match. The syntax is that
    of a QRegExp. If \a regexpMatch is FALSE, \a objName is a string
    and object names must match it exactly.

    Note that \a inheritsClass uses single inheritance from QObject,
    the way inherits() does. According to inherits(), QMenuBar
    inherits QWidget but not QMenuData. This does not quite match
    reality, but is the best that can be done on the wide variety of
    compilers Qt supports.

    Finally, if \a recursiveSearch is TRUE (the default), queryList()
    searches \e{n}th-generation as well as first-generation children.

    Installs an event filter \a filterObj on this object. For example:
    \code

    \endcode

    An event filter is an object that receives all events that are
    sent to this object. The filter can either stop the event or
    forward it to this object. The event filter \a filterObj receives
    events via its eventFilter() function. The eventFilter() function
    must return TRUE if the event should be filtered, (i.e. stopped);
    otherwise it must return FALSE.

    If multiple event filters are installed on a single object, the
    filter that was installed last is activated first.

    Here's a \c KeyPressEater class that eats the key presses of its
    monitored objects:
    \code
    class KeyPressEater : public QObject
    {
	...
    protected:
	bool eventFilter( QObject *o, QEvent *e );
    };

    bool KeyPressEater::eventFilter( QObject *o, QEvent *e )
    {
	if ( e->type() == QEvent::KeyPress ) {
	    // special processing for key press
	    QKeyEvent *k = (QKeyEvent *)e;
	    qDebug( "Ate key press %d", k->key() );
	    return TRUE; // eat event
	} else {
	    // standard event processing
	    return FALSE;
	}
    }
    \endcode

    And here's how to install it on two widgets:
    \code
	KeyPressEater *keyPressEater = new KeyPressEater( this );
	QPushButton *pushButton = new QPushButton( this );
	QListView *listView = new QListView( this );

	pushButton->installEventFilter( keyPressEater );
	listView->installEventFilter( keyPressEater );
    \endcode

    The QAccel class, for example, uses this technique to intercept
    accelerator key presses.

    \warning If you delete the receiver object in your eventFilter()
    function, be sure to return TRUE. If you return FALSE, Qt sends
    the event to the deleted object and the program will crash.

/*!
    Connects \a signal from the \a sender object to \a member in object
    \a receiver, and returns TRUE if the connection succeeds; otherwise
    returns FALSE.

    You must use the SIGNAL() and SLOT() macros when specifying the \a signal
    and the \a member, for example:
    \code
    QLabel     *label  = new QLabel;
    QScrollBar *scroll = new QScrollBar;
    QObject::connect( scroll, SIGNAL(valueChanged(int)),
                      label,  SLOT(setNum(int)) );
    \endcode

    This example ensures that the label always displays the current
    scroll bar value. Note that the signal and slots parameters must not
    contain any variable names, only the type. E.g. the following would
    not work and return FALSE:
    QObject::connect( scroll, SIGNAL(valueChanged(int v)),
                      label,  SLOT(setNum(int v)) );

    A signal can also be connected to another signal:

    \code
    class MyWidget : public QWidget
    {
	Q_OBJECT
    public:
	MyWidget();

    signals:
	void myUsefulSignal();

    private:
	QPushButton *aButton;
    };

    MyWidget::MyWidget()
    {
	aButton = new QPushButton( this );
	connect( aButton, SIGNAL(clicked()), SIGNAL(myUsefulSignal()) );
    }
    \endcode

    In this example, the MyWidget constructor relays a signal from a
    private member variable, and makes it available under a name that
    relates to MyWidget.

    A signal can be connected to many slots and signals. Many signals
    can be connected to one slot.

    If a signal is connected to several slots, the slots are activated
    in an arbitrary order when the signal is emitted.

    The function returns TRUE if it successfully connects the signal
    to the slot. It will return FALSE if it cannot create the
    connection, for example, if QObject is unable to verify the
    existence of either \a signal or \a member, or if their signatures
    aren't compatible.

    A signal is emitted for \e{every} connection you make, so if you
    duplicate a connection, two signals will be emitted. You can
    always break a connection using \c{disconnect()}.

/*!
    Disconnects \a signal in object \a sender from \a member in object
    \a receiver.

    A signal-slot connection is removed when either of the objects
    involved are destroyed.

    disconnect() is typically used in three ways, as the following
    examples demonstrate.
    \list 1
    \i Disconnect everything connected to an object's signals:
       \code
       disconnect( myObject, 0, 0, 0 );
       \endcode
       equivalent to the non-static overloaded function
       \code
       myObject->disconnect();
       \endcode
    \i Disconnect everything connected to a specific signal:
       \code
       disconnect( myObject, SIGNAL(mySignal()), 0, 0 );
       \endcode
       equivalent to the non-static overloaded function
       \code
       myObject->disconnect( SIGNAL(mySignal()) );
       \endcode
    \i Disconnect a specific receiver:
       \code
       disconnect( myObject, 0, myReceiver, 0 );
       \endcode
       equivalent to the non-static overloaded function
       \code
       myObject->disconnect(  myReceiver );
       \endcode
    \endlist

    0 may be used as a wildcard, meaning "any signal", "any receiving
    object", or "any slot in the receiving object", respectively.

    The \a sender may never be 0. (You cannot disconnect signals from
    more than one object in a single call.)

    If \a signal is 0, it disconnects \a receiver and \a member from
    any signal. If not, only the specified signal is disconnected.

    If \a receiver is 0, it disconnects anything connected to \a
    signal. If not, slots in objects other than \a receiver are not
    disconnected.

    If \a member is 0, it disconnects anything that is connected to \a
    receiver. If not, only slots named \a member will be disconnected,
    and all other slots are left alone. The \a member must be 0 if \a
    receiver is left out, so you cannot disconnect a
    specifically-named slot on all objects.
