The QChildEvent class contains event parameters for child object events.
Child events are sent immediately to objects when children are added or removed.
In both cases you can only rely on the child being a QObject (or, if QObject::isWidgetType() returns true, a QWidget). This is because in the QEvent::ChildAdded case the child is not yet fully constructed; in the QEvent::ChildRemoved
case it might have already been destructed.
The handler for these events is QObject::childEvent().
Constructs a child event object of a particular type for the child.
type can be QEvent::ChildAdded, QEvent::ChildRemoved, or QEvent::ChildPolished.
See also child().
Returns true if type() is QEvent::ChildAdded; otherwise returns false.
Returns the child object that was added or removed.
Returns true if type() is QEvent::ChildPolished; otherwise returns false.
Returns true if type() is QEvent::ChildRemoved; otherwise returns false.
