Overview
Contact data can be read through QContactDetail and all of its subclasses.
Qt project file
CONFIG += mobility
MOBILITY = contacts
symbian {
TARGET.CAPABILITY = ReadUserData WriteUserData
}
Header
// QtMobility
#include <qcontactmanager.h>
#include <qcontact.h>
#include <qcontactdetailfilter.h>
#include <qcontactphonenumber.h>
#include <qcontactemailaddress.h>
QTM_USE_NAMESPACE
private:
QPointer<QContactManager> m_contactManager;
Source
1) Create manager first, see more in Finding contact manager in Qt.
// Create manager (Symbian backend)
m_contactManager = new QContactManager("symbian");
2) Search one contact, see more in Searching contact in Qt.
QContact contact = searchContact("1234567890");
3) Reading contact detail data
3.1) Data can be read using QContactDetail subclasses (for instance, QContactDisplayLabel and QContactEmailAddress).
QContactDisplayLabel displayLabel = contact.detail(QContactDisplayLabel::DefinitionName);
QMessageBox::information(this,"QContactDisplayLabel",displayLabel.label());
QContactEmailAddress email = contact.detail(QContactEmailAddress::DefinitionName);
QMessageBox::information(this,"QContactEmailAddress",email.emailAddress());
3.2) Looping through all QContactDetail of QContact
QString s;
QList<QContactDetail> allDetails = contact.details();
foreach (const QContactDetail& detail, allDetails) {
s += detail.definitionName();
s += " : ";
QVariantMap fieldValues = detail.variantValues();
QStringList keys = fieldValues.keys();
foreach (const QString& key, keys) {
s += key + "=" + detail.value(key) + ";";
}
s += "\n";
}
// Show all QContactDetail data to the user
QMessageBox::information(this,"QContactDetail",s);
Postconditions
QContactDetail data is searched and shown to the user.
