Class: QgsFeatureSelectionModel¶
- class qgis.gui.QgsFeatureSelectionModel(model: QAbstractItemModel, featureModel: QgsFeatureModel, featureSelectionHandler: QgsIFeatureSelectionManager, parent: QObject)¶
Bases:
PyQt5.QtCore.QItemSelectionModel
Methods
emitSelectionChanged
Enables or disables synchronisation to the
QgsVectorLayer
When synchronisation is disabled, any selection change will be buffered inside this selection model.Returns the selection status of a given feature id.
Overwritten to do NOTHING (we handle selection ourselves)
Select features on this table.
- param featureSelectionManager:
Signals
pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL
- childEvent(self, QChildEvent)¶
- connectNotify(self, QMetaMethod)¶
- customEvent(self, QEvent)¶
- disconnectNotify(self, QMetaMethod)¶
- QgsFeatureSelectionModel.emitSelectionChanged(self, QItemSelection, QItemSelection)
- enableSync(self, enable: bool)¶
Enables or disables synchronisation to the
QgsVectorLayer
When synchronisation is disabled, any selection change will be buffered inside this selection model. When enabled, any buffered changes are communicated to the layer and the buffer is emptied. Mainly to be used for performance reasons, because selection change on the layer can cost time as it repaints the layer.- Parameters:
enable (bool) – The synchronisation status to set.
- isSelected(self, fid: int) bool ¶
Returns the selection status of a given feature id.
- Parameters:
fid (int) – The featureid to determine the selection status of
- Returns:
The selection status
isSelected(self, index: QModelIndex) -> bool Returns the selection status of a given QModelIndex.
- Parameters:
index – The index to determine the selection status of
- Return type:
bool
- Returns:
The selection status
- isSignalConnected(self, QMetaMethod) bool ¶
- receivers(self, PYQT_SIGNAL) int ¶
- requestRepaint¶
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

- selectFeatures(self, selection: QItemSelection, command: QItemSelectionModel.SelectionFlags | QItemSelectionModel.SelectionFlag)¶
Select features on this table. Is to be used in favor of the stock select methods.
- Parameters:
selection (QItemSelection) – The QItemSelection which will be selected
command (Union[QItemSelectionModel.SelectionFlags) – The command to apply. Select, Deselect and ClearAndSelect are processed.
