 ~QgsFieldDomainsItem () override
QString connectionUri () const
 Returns the connection URI.

 Constructor for QgsDataItem, with the specified parent item.
 ~QgsDataItem () override
virtual Q_DECL_DEPRECATED bool acceptDrop ()
 Returns whether the item accepts drag and dropped layers - e.g.

virtual QgsAbstractDatabaseProviderConnectiondatabaseConnection () const
 For data items that represent a DB connection or one of its children, this method returns a connection.
virtual void deleteChildItem (QgsDataItem *child)

virtual QgsDataItemremoveChildItem (QgsDataItem *child)
 Removes a child item and returns it without deleting it.
virtual Q_DECL_DEPRECATED bool rename (const QString &name)
 Sets a new name for the item, and returns true if the item was successfully renamed.

Constructor & Destructor Documentation

◆ QgsFieldDomainsItem()

QgsFieldDomainsItem::QgsFieldDomainsItem ( QgsDataItem parent,
const QString &  path,
const QString &  connectionUri,
const QString &  providerKey 

Constructor for QgsFieldDomainsItem, with the specified parent item.

The path argument gives the item path in the browser tree. The path string can take any form, but QgsDataItem items pointing to different logical locations should always use a different item path. The connectionUri argument is the connection part of the layer URI that it is used internally to create a connection and retrieve fields information. The providerKey string can be used to specify the key for the QgsDataItemProvider that created this item.
