[SailfishDevel] Read-only TextArea: Always keep the lines added last visible

Hi all,

I was trying to use a TextArea as a UI-visible debug log, so I can see
connection error details while I'm out using my app. The basic principle
is that the python code (pyotherside) will make a server request and
send detailed answers to the text area, which displays them. Everything
works find, except the text area doesn't auto scroll to the end when
there is more content than fits on the page. autoScrollenabled seems to
mean something entirely different, selectionStart start seems to be
read-only. I have put up an example that demonstrates, at the end of the

Does anyone know of the magic incantations needed to make sure the
latest lines are always visible?

import QtQuick 2.0
import Sailfish.Silica 1.0

Page {
    id: textAreaLogExample

    SilicaFlickable {
        TextArea {
            id: textAreaLog
            readOnly: true
            text: "Test"
            autoScrollEnabled: true

    Timer {
        interval: 500; running: true; repeat: true
        onTriggered: {
            textAreaLog.text += "\n" + new Date().getUTCSeconds() + " Log"
