Normally in the delegate class we use the model() (QAbstractItemModel) which is provided in the functions that we override. However what you set to the model()->setData() it will automatically update the item (based on the roles : DisplayRole, UserRole etc). In order to access the data you can use model->data(index,Qt::DisplayRole).toString();

thank you , got it.
so how should i got the parentWidgetItem of the currentItem?

QModelIndex parentIndex = model->parent(index);
or
QModelIndex parentIndex = index.parent();

or they are same?

Sam

Both are the same for more details you can check the documentation QAbstractItemModel::parent(const QModelIndex & index) and QModelIndex::parent()

make sure that you check if the index isValid() then only proceed with next operation.
