Overview
This code example shows how to read contacts from contact book (phonebook). User might need to read contacts programmatically by one or more reason, this code example shows how to use QtMobility Contacts APIs to read contacts from contact book.
This snippet requires ReadUserData, ReadDeviceData capabilities. Self-signing is not possible, a Developer certificate is needed to sign application for testing.
Prerequisite
- Install Qt for Symbian:Installing Qt on Symbian
- Install QtMobility APIs:Setting up environment for Qt Mobility API
Headers required
#include <qtcontacts.h>.pro file
Modify your .pro file as follows.
INCLUDEPATH += D:/QtMobility/src/contacts \
INCLUDEPATH += D:/QtMobility/src/contacts/filters \
INCLUDEPATH += D:/QtMobility/src/contacts/requests \
INCLUDEPATH += D:/QtMobility/src/contacts/details
INCLUDEPATH += D:/QtMobility/src/global
CONFIG += mobility
MOBILITY = contacts
symbian::TARGET.CAPABILITY = ReadUserData \
ReadDeviceData

}
