DelegateChooser with QSqlTableModel

sandro4912

I have a TableView which displays data from a model which is based on QSQlTableModel. Now depending on the Column I want to load a different delegate.

This is the model:

class QuestionSqlTableModel : public QSqlTableModel
{
    Q_OBJECT
public:
    explicit QuestionSqlTableModel(QObject *parent = nullptr,
                                   const QSqlDatabase &db = QSqlDatabase());

    Q_INVOKABLE QVariant data(const QModelIndex &index, int role) const override;
};

Now I though I could use DelegateChooser for this:

import QtQuick 2.15
import QtQuick.Controls 2.15
import Qt.labs.qmlmodels 1.0

ListView {
    width: 200; height: 400

    ListModel {
        id: listModel
        ListElement { type: "info"; ... }
        ListElement { type: "switch"; ... }
        ListElement { type: "swipe"; ... }
        ListElement { type: "switch"; ... }
    }

    DelegateChooser {
        id: chooser
        role: "type"
        DelegateChoice { roleValue: "info"; ItemDelegate { ... } }
        DelegateChoice { roleValue: "switch"; SwitchDelegate { ... } }
        DelegateChoice { roleValue: "swipe"; SwipeDelegate { ... } }
    }

    model: listModel
    delegate: chooser
}

Now what I want to do is this to choose:

DelegateChooser {
    id: chooser
    role: "column"
    DelegateChoice { roleValue: "0"; ItemDelegate { ... } }
    DelegateChoice { roleValue: "1"; SwitchDelegate { ... } }
    DelegateChoice { roleValue: "2"; SwipeDelegate { ... } }
}

So the question Is how can I get the current column in qml ?
