This article shows how to use native dialogs for displaying contact information on Maemo 5 devices. Note that at time of writing Qt Mobility contacts back-end allows contact management but does not allow the possibility of contact display using native dialogs. There is an outstanding bug for this functionality here: QTMOBILITY-223.

Source code

The QOssoAbookDialog class has several static methods that can be used to display Maemo5 native dialogs. Here how this class can be used:

#include "qossoabookdialog.h"
#include <QtGui>
 
int main (int argc, char **argv)
{
    QApplication app(argc, argv);
 
    QStringList IDs = QOssoABookDialog::contactChooser("Please select a contact");
    qDebug() << "MY ID" << IDs;
    foreach(QString id, IDs){
        QOssoABookDialog::contactEditor(id);
    }
 
    return app.exec();
}
