Class: QgsFeatureFilterModel

class qgis.core.QgsFeatureFilterModel(parent: QObject = None)

Bases: QgsFeaturePickerModelBase

Create a new QgsFeatureFilterModel, optionally specifying a parent.

Provides a list of features based on filter conditions. Features are fetched asynchronously.

New in version 3.0.

Parameters

parent –

QgsFeatureFilterModel.beginInsertColumns(self, QModelIndex, int, int)

QgsFeatureFilterModel.beginInsertRows(self, QModelIndex, int, int)

QgsFeatureFilterModel.beginMoveColumns(self, QModelIndex, int, int, QModelIndex, int) -> bool

QgsFeatureFilterModel.beginMoveRows(self, QModelIndex, int, int, QModelIndex, int) -> bool

QgsFeatureFilterModel.beginRemoveColumns(self, QModelIndex, int, int)

QgsFeatureFilterModel.beginRemoveRows(self, QModelIndex, int, int)

beginResetModel(self)

QgsFeatureFilterModel.changePersistentIndex(self, QModelIndex, QModelIndex)

changePersistentIndexList(self, Iterable[QModelIndex], Iterable[QModelIndex])

childEvent(self, QChildEvent)

connectNotify(self, QMetaMethod)

QgsFeatureFilterModel.createIndex(self, int, int, object: object = 0) -> QModelIndex

customEvent(self, QEvent)

QgsFeatureFilterModel.decodeData(self, int, int, QModelIndex, QDataStream) -> bool

disconnectNotify(self, QMetaMethod)

encodeData(self, Iterable[QModelIndex], QDataStream)

endInsertColumns(self)

endInsertRows(self)

endMoveColumns(self)

endMoveRows(self)

endRemoveColumns(self)

endRemoveRows(self)

endResetModel(self)

extraIdentifierValue()

extraIdentifierValues(self) → List[Any]

Allows specifying one value that does not need to match the filter criteria but will still be available in the model.

New in version 3.10.

Return type

List[Any]

extraIdentifierValuesChanged

Allows specifying one value that does not need to match the filter criteria but will still be available in the model. [signal]

identifierField(self) → str

The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer. If there are several identifier fields defined, the behavior is not guaranteed

Deprecated since version QGIS: 3.10 use identifierFields instead

Return type

str

identifierFields(self) → List[str]

The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer.

New in version 3.10.

Return type

List[str]

identifierFieldsChanged

The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer. [signal]

isSignalConnected(self, QMetaMethod) → bool

persistentIndexList(self) → List[QModelIndex]

receivers(self, PYQT_SIGNAL) → int

requestToReloadCurrentFeature()

resetInternalData(self)

sender(self) → QObject

senderSignalIndex(self) → int

setExtraIdentifierValue()

setExtraIdentifierValueToNull(self)

Allows specifying one value that does not need to match the filter criteria but will still be available in the model as NULL value(s).

New in version 3.10.

setExtraIdentifierValueUnguarded()

setExtraIdentifierValues(self, extraIdentifierValues: Iterable[Any])

Allows specifying one value that does not need to match the filter criteria but will still be available in the model.

New in version 3.10.

Parameters

extraIdentifierValues (Iterable[Any]) –

setIdentifierFields(self, identifierFields: Iterable[str])

The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer.

Note

This will also reset identifier fields to NULL

New in version 3.10.

Parameters

identifierFields (Iterable[str]) –

timerEvent(self, QTimerEvent)
