Checkboxes in QTableView with my custom model

[frankiefrank]

I read a few threads on this subject but stayed kind of confused.

I have a custom model and a QTableView, and I'm using a custom class deriving from QItemDelegate for two columns I need widgets in (a QSpinBox like in the Qt example, and a QComboBox).

Now I want to add a checkbox, but unlike the combo and spinbox, where the actual widget becomes displayed only in edit mode, I want my checkboxes to be always displayed. Of course I'll also want to connect to signals emitted from checking/unchecking.

What's the best way to add these checkboxes in my new column?

QTableView can display a checkbox by default, just enable Qt::ItemIsUserCheckable flag in the model in QAbstractItemModel::flags(). For signals when checked, you need to explicitly emit signals (user defined signals) when user checks the item, i.e. from QAbstractItemModel::setData()

You'll also need this in your data(const QModelIndex &index, int role) method:

if (role == Qt::CheckStateRole)  // this shows the checkbox
        {
            bool aBool = fieldValue;
            if (aBool)
                    return Qt::Checked;
            else
                    return Qt::Unchecked;
        }

if (role == Qt::CheckStateRole)  // this shows the checkbox
        {
            bool aBool = fieldValue;
            if (aBool)
                    return Qt::Checked;
            else
                    return Qt::Unchecked;
        }

I need the ability to show checkbox, I am still confuse on this issue. How do I set the flags. QAbstractItemModel::flags() is a getter not a setter, right?
