Class: QgsFeatureListComboBox

class qgis.gui.QgsFeatureListComboBox(parent: QWidget = None)

Bases: PyQt5.QtWidgets.QComboBox

Create a new QgsFeatureListComboBox, optionally specifying a parent.

This offers a combobox with autocompleter that allows selecting features from a layer.

It will show up to 100 entries at a time. The entries can be chosen based on the displayExpression and whenever text is typed into the combobox, the completer and popup will adjust to features matching the typed text.

New in version 3.0.
