◆ allowMove()

bool QAbstractItemModelPrivate::allowMove ( const QModelIndex & srcParent,
int start,
int end,
const QModelIndex & destinationParent,
int destinationStart,
Qt::Orientation orientation )

Returns whether a move operation is valid.

A move operation is not allowed if it moves a continuous range of rows to a destination within itself, or if it attempts to move a row to one of its own descendants.

◆ movePersistentIndexes()

void QAbstractItemModelPrivate::movePersistentIndexes ( const QList< QPersistentModelIndexData * > & indexes,
int change,
