Class: QgsAbstractGeocoderLocatorFilter

class qgis.core.QgsAbstractGeocoderLocatorFilter(name: str, displayName: str, prefix: str, geocoder: QgsGeocoderInterface)

Bases: QgsLocatorFilter

Constructor for QgsAbstractGeocoderLocatorFilter.

The name argument specifies a unique name for the filter. This should be an untranslated string identifying the filter.

The displayName argument must specify a translated, user-friendly name for the filter.

The prefix argument specifies the prefix character(s) for this filter. Prefixing a search with these characters will restrict the locator search to only include results from this filter. The prefix must consist of at least three characters.

The geocoder must specify an instance of a class which implements the QgsGeocoderInterface interface. Ownership of geocoder is not transferred, and the caller must ensure that geocoder exists for the lifetime of this filter.

An abstract base class which implements a locator filter populated from a QgsGeocoderInterface.

This base class implements the required logic to bridge a class which implements the QgsGeocoderInterface interface to a QgsLocatorFilter. It allows easy creation of a locator filter from a geocoder.

Note

This is a low-level API, designed for use by client applications which do not utilize the QGIS gui library. Usually the concrete class QgsGeocoderLocatorFilter from the gui library should be used instead.

New in version 3.18.
