QTableView make one colmum editable

[Andy314]

I found a lot in the internet about it, but I have one problem.
I made a QFilterSortProxyModel and want overwrite the flags.
Is there a more easy solution for this common task ?

class SpecialProxy: public QSortFilterProxyModel
{public:
    SpecialProxy(QObject* o):QSortFilterProxyModel(o) {}
    virtual Qt::ItemFlags flags(const QModelIndex& index) const override
        {
           Qt::ItemFlags result = this->sourceModel()->flags(index);
           if (index.column() == 3) 
           {
               result |= Qt::ItemIsEditable;
           }
           return result;
        }

Must I enable all edit flags in the QTableView and disable the editable-flag in proxy model ? How get I the default flags ?
The sourcemodel seen to have not the correct flags! If I use the code above no selection of the whole table works (nor editing works). Why that ?

Just call the base class version

class SpecialProxy: public QSortFilterProxyModel
{public:
    SpecialProxy(QObject* o):QSortFilterProxyModel(o) {}
    virtual Qt::ItemFlags flags(const QModelIndex& index) const override
        {
           Qt::ItemFlags result = QSortFilterProxyModel::flags(index);
           if (index.column() == 3) 
           
               result |= Qt::ItemIsEditable;
           
else
result &= ~Qt::ItemIsEditable; // All other columns not editable
           return result;
        }

Hello @VRonin,
ok thank you this works.

But the changing in the database does not. After refresh I get once a again the same data.

    TPModel = new QSqlTableModel (this);
    TPModel->setTable("qryTransportGUI");
    SpecialProxy *Proxy = new SpecialProxy(this);
    Proxy->setSourceModel(TPModel);
    ui->TPView->setModel(Proxy);

The edit action does not write in the queried data !

Hi,

Did you check the edit strategy of your model ?
