| virtual QVector< QgsDataItem * > | createChildren () |
| Create children. | |
| virtual QgsAbstractDatabaseProviderConnection * | databaseConnection () const |
| For data items that represent a DB connection or one of its children, this method returns a connection. | |
| virtual void | deleteChildItem (QgsDataItem *child) |
