verticalCenter in ListView (Delegate) not working

[QTmox]

Hey guys! I'm currently working on an exercise that revolves around ListViews, delegates and so on.

This is what my application currently looks like:

http://www.directupload.net/file/d/4141/obiumyrm_jpg.htm

All I want is to center the second column of text just like the first column. However, I only manage to get it to the top or the bottom of the row - never in the center.

Can any of you point out my mistake why I managed to but the first column of text nicely into the row's center but can't get it to work on the second one? Thanks in advance! :)

This is my source code:

main.qml

import QtQuick 2.3
import QtQuick.Controls 1.2

ApplicationWindow {
    id: root

width: 800; height: 600   

function readFile() {
    var request = new XMLHttpRequest()

    request.open('GET', 'qrc:/Kommilitonen.txt')
    request.onreadystatechange = function(event) {


        if(request.readyState == XMLHttpRequest.DONE)
        {
            console.log(request.responseText)
            view.model = JSON.parse(request.responseText)
        }
    }

    request.send();
}

ListView {
    id: view

    property real delegateOpacity: 0.5

    anchors {fill: parent; margins: 2}

    delegate: KommiDelegate {}

    spacing: 4
    cacheBuffer: 50
}

Component.onCompleted: {
    root.visible = true
    readFile();
}

}

KommiDelegate.qml

import QtQuick 2.3

Rectangle {
id: delegate01
anchors{left: parent.left; right: parent.right}
height: 100
border.width: 2
border.color: "lightsteelblue"
radius: 10
clip: true
opacity: 0.5
scale: 0.9

NumberAnimation{
    id: animateOpacity
    target: delegate01
    properties: "opacity"
    from: 0.9
    to: 1.0
    easing {type: Easing.OutBack; overshoot: 500}
}



MouseArea {
    anchors.fill: parent
    onPressed: {
        if(parent.opacity == 0.5)
            parent.opacity = 1.0
        else
            parent.opacity = 0.5
        if(parent.scale==0.9)
            parent.scale = 1.0
        else
            parent.scale = 0.9

    }
}

    Image {
        id: img
        anchors.left: parent.left
        anchors.leftMargin: 20
        source: modelData.image
        smooth: true
        opacity: 0.3
        Behavior on opacity {NumberAnimation{easing.type:Easing.OutQuad}}

    }

    Column {
        id: column
        height: 50
        anchors.verticalCenter: parent.verticalCenter
        anchors.left: img.right
        anchors.leftMargin: 20
        Text{text: 'First Name: ' + modelData.forename}
        Text{text: 'Name: ' + modelData.name}
        Text{text: 'University Course: ' + modelData.course}
        Text{text: 'Age: ' + modelData.age}


    }





ListView
{
    anchors.left: column.right
    anchors.leftMargin: 20
    anchors.verticalCenter: parent.verticalCenter

    id: viewClass

    delegate: ClassDelegate {}

    spacing: 4
    cacheBuffer: 50

    model: modelData.modules
}

}

ClassDelegate.qml

import QtQuick 2.0


Rectangle {
    id: classDelegate
    anchors{left: parent.left; right: parent.right}
    visible: true

        Column {

            id: column2
            Text{text: 'Description: ' + modelData.name}
            Text{text: 'ID: ' + modelData.identificationCode}
            Text{text: 'Severity: ' + modelData.severity}
            Text{text: 'Group: ' + modelData.lernenGroup}
        }

}
