[Qt-qml] setData from QML on a qabstractitemmodel

[michael.brasser at nokia.com]

Hi,

Unfortunately there is no automatic way to do this at the moment (http://bugreports.qt.nokia.com/browse/QTBUG-7932 is the issue that tracks this). One solution at this point would be to add a custom slot (or Q_INVOKABLE) to your model that can be called from QML -- this is how the ListModel element handles it. For example, something like

void setModelProperty(int index, QString property, QVariant value);

could be called from your delegate:

Item {
    id: delegate
    ...
    TextInput { id: label; ... }
    MouseArea {
        anchors.fill: parent
        // assuming your model has been exposed to QML as "myModel", and has a role name "name" which takes a string
        onClicked: myModel.setModelProperty(index, "name", label.text)
    }
}

Regards,
Michael
