What is the equivalent of QgsMapToolIdentifyFeature in PyQGIS 3?

Question

I was trying to use the QgsMapToolIdentifyFeature() tool as shown in an answer of StackOverflow, but when executed it gave the error:

'QgisInterface' object has no attribute 'QgsMapToolIdentifyFeature'

I am assuming it was deprecated, in that case how do I call this tool in PyQgis3.4?

Answer 1

QgsMapToolIdentifyFeature is not deprecated in QGIS 3

https://qgis.org/api/classQgsMapToolIdentifyFeature.html

self.iface.QgsMapToolIdentifyFeature(atriVector, f) is not correct way,you need create a instance for QgsMapToolIdentifyFeature and set map tool after.

I add a minimal example

from qgis.gui import QgsMapToolIdentifyFeature
from PyQt5.QtGui import QColor

def onFeatureIdentified(feature):
    fid = feature.id()
    print ("feature selected : " + str(fid))

layer = iface.activeLayer()
mc=iface.mapCanvas()
mapTool = QgsMapToolIdentifyFeature(mc)
mapTool.setLayer(layer)
mc.setMapTool(mapTool)
mapTool.featureIdentified.connect(onFeatureIdentified)
