Need help in Mobility API

[doforumda]

hi i am trying and example on this link "Your text to link here...":http://www.forum.nokia.com/document/Mobile_Hands-on_Labs/Qt/MobilityLocation/03_01.html. When i run this code it does not give any errors but it also does not run properly. It does not show location as well as does not fetch maps from google maps. I am trying this in Qt Simulator
here is the complete code
mainwindow.h

Have you debugged and checked if the map is being fetched
