Change signal emitted for undefined value

    XMLWordPrintable

Details

    Description

      This code triggers the onSomethingChanged signal handler each time something is set with undefined, which it already is - this is not a change.

      import QtQuick 2.3

Item {
    id: root

    property var something

    onSomethingChanged: {
        console.log("Something changed!")
    }

    Timer {
        running: true
        interval: 200
        repeat: true
        onTriggered: {
            // if (root.something !== undefined)
            root.something = undefined;
        }
    }
}
