qchildevent.3qt - Man Page

#include <qevent.h>

Inherits QEvent.

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.

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.

Returns the child widget that was inserted or removed.

Returns TRUE if the widget received a new child; otherwise returns FALSE.

Returns TRUE if the object lost a child; otherwise returns FALSE.
