Get the identified feature

Question

I use QgsMapToolIdentifyFeature to trap the featureIdentified signal, so i can get some information from the identified feature and show it in a panel within my plugin.

here is the code, my problem is the connection between the featureIdentified signal and my slot is not works:

def onFeatureIdentified(self, ff):
    print("feature selected")

def run(self):
    f = QgsMapToolIdentifyFeature(self.iface.mapCanvas(), self.iface.activeLayer())
    f.featureIdentified.connect(self.onFeatureIdentified)

i don't know that's the problem in my code since it doesn't raise any error.

This is a simple code for connect your QgsMapToolIdentifyFeature signal.

from qgis.gui import QgsMapToolIdentifyFeature

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

mapTool = None
mc=iface.mapCanvas()
lyr=iface.activeLayer()
mapTool = QgsMapToolIdentifyFeature(mc)
mapTool.setLayer(lyr)
mc.setMapTool(mapTool)
mapTool.featureIdentified.connect(onFeatureIdentified)

And when click in a feature print the id.

To stick with your code :

def onFeatureIdentified(self, ff):
    print("feature selected")

def run(self):
    mCanvas = self.iface.mapCanvas()
    f = QgsMapToolIdentifyFeature(mCanvas, self.iface.activeLayer())
    mCanvas.setMapTool(f)
    f.featureIdentified.connect(self.onFeatureIdentified)
