selectedFeatures()

Implemented in QgsVectorLayerSelectionManager, and QgsGenericFeatureSelectionManager.

selectionChanged

void QgsIFeatureSelectionManager::selectionChanged ( const QgsFeatureIds &  selected, const QgsFeatureIds &  deselected, const bool  clearAndSelect  )

signal

This signal is emitted when selection was changed.

Parameters

selected	Newly selected feature ids
deselected	Ids of all features which have previously been selected but are not any more
clearAndSelect	In case this is set to true, the old selection was dismissed and the new selection corresponds to selected

setSelectedFeatures()

virtual void QgsIFeatureSelectionManager::setSelectedFeatures ( const QgsFeatureIds &  ids )

pure virtual

Change selection to the new set of features.

Dismisses the current selection. Will emit the selectionChanged( const QgsFeatureIds&, const QgsFeatureIds&, bool ) signal with the clearAndSelect flag set.

Parameters

ids	The ids which will be the new selection
