• def polished ()

• def removed ()

Detailed Description

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 isWidgetType() returns true , a QWidget ). This is because in the ChildAdded case the child is not yet fully constructed; in the ChildRemoved case it might have already been destructed.

The handler for these events is childEvent() .
