QSize CSmsThreadListWidgetItem::sizeHint ( const QStyleOptionViewItem & option, const QModelIndex & index ) const{
return QSize(200, 100); // very dumb value
}

item = new QListWidgetItem();
item->setData(Qt:isplayRole, title);
item->setData(Qt::UserRole, sms->getMessage());
item->setData(Qt::UserRole +1, sms->getDateAndTime());
item->setData(Qt:ecorationRole, QPixmap(fileimage_));
this->listWidget->addItem(item);
