Class: QgsFeaturePickerWidget

class qgis.gui.QgsFeaturePickerWidget

Bases: PyQt5.QtWidgets.QWidget

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 3.14.

QgsFeaturePickerWidget(parent: QWidget = None) Create a new QgsFeaturePickerWidget, optionally specifying a parent.

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.
