[edit] Qt project file

CONFIG += mobility
MOBILITY = contacts
symbian {
TARGET.CAPABILITY = ReadUserData WriteUserData
}

[edit] Header

#include <QtGui/QMainWindow>
#include <QPointer>
 
// QtMobility
#include <qcontactmanager.h>
#include <qcontact.h>
QTM_USE_NAMESPACE
 
class qtSnippets : public QMainWindow
{
Q_OBJECT
 
public:
qtSnippets(QWidget *parent = 0);
~qtSnippets();
 
private slots:
void createManager();
 
private:
QPointer<QContactManager> m_contactManager;
};

[edit] Source

#include <QTimer>
#include <QMessageBox>
 
qtSnippets::qtSnippets(QWidget *parent)
: QMainWindow(parent)
{
// Let application to startup fully and then
// create manager
QTimer::singleShot(0, this, SLOT(createManager()));
}
 
qtSnippets::~qtSnippets()
{
delete m_contactManager;
}
 
void qtSnippets::createManager()
{
// Get list of different contact back-ends
QStringList availableManagers = QContactManager::availableManagers();
 
QList<QContactLocalId> contactIds;
// Try to find contacts from some back-end
while (!availableManagers.isEmpty()) {
// Get some manager
m_contactManager = new QContactManager(availableManagers.first());
availableManagers.removeFirst();
 
// Contacts exists?
contactIds = m_contactManager->contactIds();
if (!contactIds.isEmpty()) {
// Contact found
availableManagers.clear();
break;
}
else {
// Not found, try the next manager
delete m_contactManager;
m_contactManager = 0;
}
}
 
// Use default if no contact found from any back-end
if (!m_contactManager) {
m_contactManager = new QContactManager();
}
 
// Show message to the user
QString msg = QString("Manager %1 created, that has %2 contacts")
.arg(m_contactManager->managerName()).arg(contactIds.count());
QMessageBox::information(this,"Contacts",msg);
}

You can also create QContactManager to stack using symbian or maemo5 backend keys:

// Create manager (Symbian backend)
QContactManager contactManager("symbian");
// Create manager (Maemo 5, Nokia N900 backend)
QContactManager contactManager("maemo5");


[edit] Postconditions

Contact manager is found.
