Is there any common elements between dynamic objects?

[PawlosCK]

Hi. I have a little problem. I prepared listview and I am creating 3 the same objects with the same parameters. First object set correct value (0), and object number 2 and 3 set value 22. Why?

main.qml

 Component.onCompleted:
    {
        object_infinite.visible = true
        object_infinite.setValues(0, 23, 2)
//        object_infinite.setValues()

//        object_infinite.setGradientColor("transparent")
        object_infinite.setBorderSize(1)

        object_infinite.x=150
        object_infinite.y=150

        object_infinite.width=120
        object_infinite.height=270

////////////////////////////////////////////////////////////


        object_infinite2.visible = true

        object_infinite2.x=270
        object_infinite2.y=150

        object_infinite2.width=120
        object_infinite2.height=270

        object_infinite2.setValues(0, 23, 2)
//        object_infinite2.setValues(0, 59, 2)

        object_infinite2.setBorderSize(1)

////////////////////////////////////////////////////////////

        object_infinite3.visible = true

        object_infinite3.x=390
        object_infinite3.y=150

        object_infinite3.width=120
        object_infinite3.height=270

        object_infinite3.setValues(0, 23, 2)
//        object_infinite3.setValues(0, 59, 2)

        object_infinite3.setBorderSize(1)

    }

Problem solved

Function setValues should be run as last. Listview didn't have correct position and size.

        object_infinite.x=150
        object_infinite.y=150
        object_infinite.width=120
        object_infinite.height=270
        object_infinite.setBorderSize(1)
        object_infinite.setValues(0, 23, 2)
        object_infinite.visible = true
