Access UI from QML



  • Hey,

    I'm trying to access UI elements from my QML script:

    For example accessing bt_start in the forms qml

    UI QML:

    Item {
    width: 800
    visible: true

    Column {
        id: column
        x: 0
        y: 0
        width: 800
        height: 480
        spacing: 0
    
        GroupBox {
            id: g_Preferences
            width: 800
            height: 120
            spacing: -5
            clip: false
            title: qsTr("Preferences")
    
            Column {
                id: column2
                width: 776
                height: 100
                spacing: 1
    
                Row {
                    id: row3
                    width: 800
                    height: 30
                    spacing: 20
    
                    Button {
                        id: bt_start
                        height: 20
                        text: qsTr("Start")
                        anchors.verticalCenter: parent.verticalCenter
                    }
    

    QML:

    Window
    {
    width: 800
    height: 320

    MyForm
    {
     id: qFrom
    }
    
    
    Connections
    {
    	onQmlSetDaemonEnabled(enabled)
    	{
    		bt_start.enabled: enabled //bt_start not found
    	}
    }
    
    bt_start.enabled: enabled 
    
    error: bt_start is not defined
    

    using the form:

    qForm.bt_start  
    error: TypeError: Type error
    

    can anyone help?

    I've only found those solution on stack and qt



  • ok it seems like i had to export it in QT Creator which generates an property alias for the object
