# qchildevent(3qt)

Event parameters for child object events

## 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.
