Class: QgsIFeatureSelectionManager

class qgis.gui.QgsIFeatureSelectionManager

Bases: PyQt5.QtCore.QObject

Is an interface class to abstract feature selection handling.

e.g. QgsVectorLayer implements this interface to manage its selections.

Methods

childEvent

connectNotify

customEvent

deselect

Deselect features by feature ids.

disconnectNotify

isSignalConnected

receivers

select

Select features by feature ids.

selectedFeatureCount

Returns the number of features that are selected in this layer.

selectedFeatureIds

Returns reference to identifiers of selected features

sender

senderSignalIndex

setSelectedFeatures

Change selection to the new set of features. Dismisses the current selection. Will emit the selectionChanged( const :py:class:`QgsFeatureIds`&, const :py:class:`QgsFeatureIds`&, bool ) signal with the clearAndSelect flag set.

select(self, ids: object)

Select features by feature ids.

Parameters

ids (object) –

selectedFeatureCount(self) int

Returns the number of features that are selected in this layer.

Return type

int

selectedFeatureIds(self) object

Returns reference to identifiers of selected features

Return type

object

Returns

A list of QgsFeatureId’s

selectionChanged

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

sender(self) QObject
senderSignalIndex(self) int
setSelectedFeatures(self, ids: object)

Change selection to the new set of features. Dismisses the current selection. Will emit the selectionChanged( const :py:class:`QgsFeatureIds`&, const :py:class:`QgsFeatureIds`&, bool ) signal with the clearAndSelect flag set.

Parameters

ids (object) – The ids which will be the new selection

timerEvent(self, QTimerEvent)
