I'm new to QGIS and python as well.

I need attributes and their values of a selected vector layer, in the similar manner as Identify Feature works only difference is I don't wish to show them in a dialog box.

For a better approach I went through Cookbook and few of posts on GIS and have tried function like getFeatures() but no success.

if rect is a Qgsrectangle centered in the point clicked on canvas, then the code is synthetically

request = QgsFeatureRequest(rect)
for feat in layer.getFeatures(request):
    <yout code> of the QgsFeature "feat"
0
def changeValue(self,point,button):
    request = QgsFeatureRequest()
    self.dlg.lineEdit.setText(str(request))
    self.dlg.show()

Above function resulted to the string below in lineEdit

  • @NathanW First of all thnkx for answering now following Luigi's answer when I tried the code I've posted above this string appeared in the code below <qgis.core.QgsFeatureRequest object at 0X048E2DB0> – Prashant Oct 16 '14 at 5:38
  • That is because you are not mean to use it like that. Do exactly what Luigi posted. – Nathan W Oct 19 '14 at 7:18
