QML Combobox with QStringListModel

[Valerian]

Hi all,

I have a QStringListModel which is configured using the setStringList method.

I'm trying to use this model in QML Combobox.

I can't find a way to do so.

Please suggest.

@Valerian
QStringListModel::setStringList() is neither a slot nor declared invokable, thus you have no chance to call it from QML.
You would need to subclass QStringListModel class and add a callable method yourself. Don't forget to register this custom list model type.

@raven-worx But QStringListModel inherits QAbstractItemModel.

And I have exposed this model to qml using setContextProperty but I can't find the role name to be used in QML

@Valerian
k, i thought you want to call the setStringList() method from within QML.
Try to register QStringListModel class - using qmlRegisterUncreatableType() is sufficient

The missing piece is probably to specify "display" as a text role. Any QAbstractItemModel derivative model has a bunch of default roles. ComboBox doesn't know which one to show:

ComboBox {
    textRole: "display" // <==
    model: stringListModel
    anchors.centerIn: parent
}

@jpnurmi Hi,

Thanks for the reply.

Is there any way to disable selection in the combobox? I want to use the combobox to show the first item and not allow click on the item at index 1 or index 2 .

Kindly advice
