273 friend class TestQgsFeatureListComboBox;
Animated icon is keeping an animation running if there are listeners connected to frameChanged.
Provides a list of features based on filter conditions.
This offers a combobox with autocompleter that allows selecting features from a layer.
void allowNullChanged()
Determines if a NULL value should be available in the list.
void modelUpdated()
The underlying model has been updated.

The identifier value of the currently selected feature.
void sourceLayerChanged()
The layer from which features should be listed.
void currentFeatureChanged()
Emitted when the current feature changes.

void identifierFieldChanged()
Field name that will be used to uniquely identify the current feature.
void filterExpressionChanged()
An additional expression to further restrict the available features.
This class wraps a request for features to a vector layer (or directly its vector data provider).
