    Re: Global variable problem with qml

    have you moved all your global variables to a single JS file that starts with the line ".pragma library" ?

    Note also that changes to the JS variables do not automatically transfer to QML code that uses them. For example

    Code:
    // In JS file
    .pragma library
    var someText = "ABCD"
    
    // in QML file
    import "global.js" as MyVariables
    Text  { text: MyVariables.someText }
    
    // in another QML file
    import "global.js" as MyVariables
    Timer { onTrigged: MyVariables.someText = "You will not see this" ; .... }
    //
    the text is not automatically updated when "MyVariables.someText" changes. I have no idea why this limitation exists.
