HI, you can read the documentation:

@
void QComboBox::setView(QAbstractItemView * itemView)

i have implemented this in customdelegate but not working

i have read, the documentation of setView in Qtassistant , he says
that if we use (QListWidget, QTableWidget or QTreeWidget) make sure to call setModel() on the combobox with the convenience widgets model before calling this function.

but i don't know how i can setModel() to Qcombobox
@
QWidget *comboBoxDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
if(index.column() != 1 )
return QStyledItemDelegate::createEditor(parent, option, index);

QComboBox* editor = new QComboBox(parent);
QTableWidget *viewTableVente = new QTableWidget(parent);
QStringList listTable;
listTable << "N° article" << "Désignation" << "Qte" << "Prix/U" <<             "Montant";
viewTableVente->setRowCount(1);
viewTableVente->setColumnCount(5);
viewTableVente->setHorizontalHeaderLabels(listTable);

editor->setModel(???????????????) ;
editor->setView(viewTableVente);
return editor;

and where is your data coming from? Why do you wanna use a QTableView in first place when you don't even have a idea how your model will look like?!

Why do you wanna use a QTableView ??
i have use Qtablewidget just for try, so i must use Qtableview because my data is not editable

in first place when you don’t even have a idea how your model will look like?!

i haven't not an idea if use the model of myQtableview or another model
Stupidity!! :)
now it working thank's

@ if(index.column() != 1 )
return QStyledItemDelegate::createEditor(parent, option, index);

QComboBox* editor = new QComboBox(parent);
editor->setStyleSheet("QComboBox { border: 1px solid gray;"
                      "border-radius: 3px;"
                       "}"
                      );

QTableView *designationTableView = new QTableView(parent);
editor->setModel(m_designationModel);
editor->setView(designationTableView);
editor->setEditable(true);
if(m_db->open())
{
    m_designationModel->setQuery("select * from Produit");
    designationTableView->setModel(m_designationModel);

}
    return editor;

}
