QCombobox as QTableView delegate

[martonmiklos]

Hello all,

I would like to display a QComboBox in my QTableView.
I have tried to use the QItemDelegate, but it only shows it when I editing the cell.
Now I am using the QStyledItemDelegate in the following way:

void FuseDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    painter->save();
    switch(index.model()->data(index, Qt::UserRole).toInt())  {
    case FuseBitField_boolean: {
            QCheckBox *editor = new QCheckBox();
            editor->setGeometry(option.rect);
            editor->render(painter);
        } break;
    case FuseBitField_enum: {
            QComboBox *editor = new QComboBox();
            editor->setGeometry(option.rect);
            editor->render(painter);
        } break;
    default:
        return QStyledItemDelegate::paint(painter, option, index);
    }
    painter->restore();
}

void FuseDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    painter->save();
    switch(index.model()->data(index, Qt::UserRole).toInt())  {
    case FuseBitField_boolean: {
            QCheckBox *editor = new QCheckBox();
            editor->setGeometry(option.rect);
            editor->render(painter);
        } break;
    case FuseBitField_enum: {
            QComboBox *editor = new QComboBox();
            editor->setGeometry(option.rect);
            editor->render(painter);
        } break;
    default:
        return QStyledItemDelegate::paint(painter, option, index);
    }
    painter->restore();
}

To copy to clipboard, switch view to plain text mode 

But it does not displays anything. Editing works fine.

Is it possible to show a a widget with a delegate in non editing mode, or I should base my design on QTableWidget, and use addCellWidget()?
