String List Model Example

A model may be a simple ‘list’, which provides the contents of the list via the modelData role.

stringlistmodel.py

from pathlib import Path
import sys
from PySide6.QtCore import QUrl
from PySide6.QtGui import QGuiApplication
from PySide6.QtQuick import QQuickView

# This example illustrates exposing a QStringList as a model in QML

if __name__ == '__main__':
    app = QGuiApplication(sys.argv)

    dataList = ["Item 1", "Item 2", "Item 3", "Item 4"]

    view = QQuickView()
    view.setInitialProperties({"model": dataList })

    qml_file = Path(__file__).parent / "view.qml"
    view.setSource(QUrl.fromLocalFile(qml_file))
    view.show()

    r = app.exec()
    del view
    sys.exit(r)

view.qml

import QtQuick

ListView {
    width: 100
    height: 100
    required model

    delegate: Rectangle {
        required property string modelData
        height: 25
        width: 100
        Text { text: parent.modelData }
    }
}
