Hi pixbyte!
In case if you use QListWidget, you can just set the widget for an item:
@QCheckBox *myItem = new QCheckBox(this);
//settings data for item
QListWidgetItem *item = new QListWidgetItem();
item->setSizeHint(QSize(0,60));
ui->listWidget->addItem(item);
ui->listWidget->setItemWidget(item,myItem);@

but if you want use QListView, you should override the QItemDelegate's paint for a view:
@if(index.column()==cbxColumnNumber)
{
bool checked = index.model()->data(index, Qt::DisplayRole).toBool();

  QStyleOptionButton check_box_style_option;
  check_box_style_option.state |= QStyle::State_Enabled;
  if (checked) {
    check_box_style_option.state |= QStyle::State_On;
  } else {
    check_box_style_option.state |= QStyle::State_Off;
  }
  check_box_style_option.rect = CheckBoxRect(option);

  QApplication::style()->drawControl(QStyle::CE_CheckBox,
                                     &check_box_style_option,
                                     painter);
}
else
{
    QItemDelegate::paint(painter, option, index);
}@

for more information see:
"http://doc.qt.digia.com/qt/qitemdelegate.html":http://doc.qt.digia.com/qt/qitemdelegate.html
or
use QStandardItemModel as a model and make items checkable with QStandardItem::setCheckable ( bool checkable ) method.

Using QListView and QStandardItemModel is the easiest option
