Signals

void delegateChanged ()
 
- Signals inherited from QQmlComponent
void statusChanged (QQmlComponent::Status)
 Emitted whenever the component's status changes.
 
void progressChanged (qreal)
 Emitted whenever the component's loading progress changes.
 
- Signals inherited from QObject
void destroyed (QObject *=nullptr)
 This signal is emitted immediately before the object obj is destroyed, after any instances of QPointer have been notified, and cannot be blocked.
 
void objectNameChanged (const QString &objectName, QPrivateSignal)
 This signal is emitted after the object's name has been changed.
