NAME

       QChildEvent - Event parameters for child object events

SYNOPSIS

       #include <qevent.h>

       Inherits QEvent.

   Public Members
       QChildEvent ( Type type, QObject * child )
       QObject * child () const
       bool inserted () const
       bool removed () const

DESCRIPTION

       The QChildEvent class contains event parameters for child object events.

       Child events are sent to objects when children are inserted or removed.

       A ChildRemoved event is sent immediately, but a ChildInserted event is posted (with QApplication::postEvent()).

       Note that if a child is removed immediately after it is inserted, the ChildInserted event may be suppressed, but the ChildRemoved event
       will always be sent. In this case there will be a ChildRemoved event without a corresponding ChildInserted event.

       The handler for these events is QObject::childEvent().

       See also Event Classes.

MEMBER FUNCTION DOCUMENTATION

QChildEvent::QChildEvent ( Type type, QObject * child )
       Constructs a child event object. The child is the object that is to be removed or inserted.

       The type parameter must be either QEvent::ChildInserted or QEvent::ChildRemoved.

QObject * QChildEvent::child () const
       Returns the child widget that was inserted or removed.

bool QChildEvent::inserted () const
       Returns TRUE if the widget received a new child; otherwise returns FALSE.

bool QChildEvent::removed () const
       Returns TRUE if the object lost a child; otherwise returns FALSE.

NAME

       QTimerEvent - Parameters that describe a timer event

SYNOPSIS

       #include <qevent.h>

       Inherits QEvent.

   Public Members
       QTimerEvent ( int timerId )
       int timerId () const

DESCRIPTION

       The QTimerEvent class contains parameters that describe a timer event.

       Timer events are sent at regular intervals to objects that have started one or more timers. Each timer has a unique identifier. A timer is
       started with QObject::startTimer().

       The QTimer class provides a high-level programming interface that uses signals instead of events. It also provides one-shot timers.

       The event handler QObject::timerEvent() receives timer events.

       See also QTimer, QObject::timerEvent(), QObject::startTimer(), QObject::killTimer(), QObject::killTimers(), and Event Classes.

MEMBER FUNCTION DOCUMENTATION

QTimerEvent::QTimerEvent ( int timerId )
       Constructs a timer event object with the timer identifier set to timerId.

int QTimerEvent::timerId () const
       Returns the unique timer identifier, which is the same identifier as returned from QObject::startTimer().

       Example: dclock/dclock.cpp.
