Member Function Documentation

virtual void QgsIFeatureSelectionManager::deselect ( const QgsFeatureIds ids)
pure virtual

Deselect features.

Parameters
idsFeature ids to deselect

Implemented in QgsVectorLayerSelectionManager, and QgsGenericFeatureSelectionManager.

virtual void QgsIFeatureSelectionManager::select ( const QgsFeatureIds ids)
pure virtual

Select features.

Parameters
idsFeature ids to select

Implemented in QgsVectorLayerSelectionManager, and QgsGenericFeatureSelectionManager.

See Also
selectedFeatures()

Implemented in QgsVectorLayerSelectionManager, and QgsGenericFeatureSelectionManager.

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

This signal is emitted when selection was changed.

Parameters
selectedNewly selected feature ids
deselectedIds of all features which have previously been selected but are not any more
clearAndSelectIn case this is set to true, the old selection was dismissed and the new selection corresponds to selected
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( QgsFeatureIds, QgsFeatureIds, bool ) signal with the clearAndSelect flag set.

Parameters
idsThe ids which will be the new selection

Implemented in QgsVectorLayerSelectionManager, and QgsGenericFeatureSelectionManager.
