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

	/* appens it to list widget to display on screen*/
	foreach (const QContactLocalId& id, contactIds) 
	{
        currContact = contactManager->contact(id);
        QString nameAndNumber(currContact.displayLabel() + ": " + currContact.detail(QContactPhoneNumber::DefinitionName).value(QContactPhoneNumber::FieldNumber));   
        listWidget->addItem(nameAndNumber);
    }
}
