QtCore Settings does not support ini files located in resources

Richard Buchmann

Hi,

Qt.labs.settings (Qt5.15) supports read/write from/to files located in resources.
After upgrading to Qt6.2, my legacy code still works.
After upgrading to Qt6.5.1/Qt6.5.2, my application crashes in QQmlApplicationEngine::load function.
QtCore Settings seems to have the same behavior.

I wrote an application sample to show you:

import QtQuick
import QtQuick.Controls
import QtQuick.Window

import QtCore  // for Settings (Qt >= 6.5)
// import Qt.labs.settings 1.0  // for Settings (Qt < 6.5)

Window {
    width: 640
    height: 480
    visible: true

    Rectangle {
        width: 100
        height: 100
        color: "red"
        border.color: "black"
        border.width: 5
        radius: 10
        Label {
            id: label
            anchors.centerIn: parent
            text: "TBD"

            Settings {
                category: "test"
                location: ":/test_settings.ini"  // NOK (Qt == 6.5)
                // location: encodeURIComponent(":test_settings.ini")  // NOK (Qt == 6.5)
                // location: "qrc://test_settings.ini"  // NOK (Qt == 6.5)
                // no location                      // OK (Qt == 6.5)
                // fileName: ":/test_settings.ini"  // OK (Qt < 6.5)                                     
                property alias text: label.text
            }
        }
    }
}

# ini file in resources
[test]
text=from resource

# ini file in local storage
[test]
text=from local

In this example, the application displays the wrong text. In Qt6.5, it always read from local storage. Never from resources.

Thank you for your answer in advance!

@Richard-Buchmann I guess I put this issue in the wrong place. I send a bug report there : https://bugreports.qt.io/browse/QTBUG-116681
