Class: QgsFeatureFilterModel¶
- class qgis.core.QgsFeatureFilterModel¶
Bases:
QgsFeaturePickerModelBase
Provides a list of features based on filter conditions. Features are fetched asynchronously.
New in version 3.0.
QgsFeatureFilterModel(parent: QObject = None) Create a new
QgsFeatureFilterModel
, optionally specifying aparent

Allows specifying one value that does not need to match the filter criteria but will still be available in the model.
The identifier field should be a unique field that can be used to identify individual features.

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).

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL
types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.
- Parameters
name (str = ...) –
revision (int = ...) –
arguments (Sequence = ...) –
- Return type
PYQT_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.
