Constructor & Destructor Documentation

◆ QQmlPartsModel()

QQmlPartsModel::QQmlPartsModel ( QQmlDelegateModel model,
const QString part,
QObject parent = nullptr 
)

\qmlsignal QtQml.Models::DelegateModelGroup::changed(array removed, array inserted)

This signal is emitted when items have been removed from or inserted into the group.

Each object in the removed and inserted arrays has two values; the index of the first item inserted or removed and a count of the number of consecutive items inserted or removed.

Each index is adjusted for previous changes with all removed items preceding any inserted items.
