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.
