QgsFieldDomainsItem(parent: QgsDataItem, path: str, connectionUri: str, providerKey: str) 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.

customEvent(self, QEvent)
deferredDelete(self) bool

The item is scheduled to be deleted. E.g. if deleteLater() is called when item is in Populating state (createChildren() running in another thread), the deferredDelete() returns True and item will be deleted once Populating finished. Items with slow reateChildren() (for example network or database based) may check during createChildren() if deferredDelete() returns True and return from createChildren() immediately because result will be useless.

disconnectNotify(self, QMetaMethod)
icon(self) QIcon
Return type

QIcon

isSignalConnected(self, QMetaMethod) bool
populate(self, children: Iterable[QgsDataItem])
populate(self, foreground: bool = False) None
