How do I pass a value along when attempting to execute an external process using Qt.openUrlExternally

[Marika]

I am creating an app written in QML, that has a button that when clicked runs a bat file. I can see the bat file executes, but i need to be able to pass to the batch file a value (to be used to set a folder location inside the batch file). How can I pass the value along when I execute the bat file? This is what my QML code looks like:

    MenuButton {
        labelText: "Run lupdate"
        mouseButton.onClicked: {
            Qt.openUrlExternally("run-lupdate.bat")
        }
    }

I'm looking for something like:

    Qt.openUrlExternally("run-lupdate.bat","C:\Temp")
