You need to set the currentIndex
as well.
testme.qml
import QtQuick 2.2
import QtQuick.Controls 1.1
import QtQuick.Window 2.0
ApplicationWindow {
title: qsTr("Hello World")
width: 300
height: 240
ScrollView {
anchors.fill: parent
ListView {
anchors.fill: parent
id: messageList
model: messageModel
delegate: Text { text: mytextrole }
highlight: Rectangle { color: "red" }
highlightMoveDuration: 0
onCountChanged: {
var newIndex = count - 1 // last index
positionViewAtEnd()
currentIndex = newIndex
}
}
}
ListModel {
id: messageModel
ListElement { mytextrole: "Dog"; }
ListElement { mytextrole: "Cat"; }
}
Timer {
property int counter: 0
running: true
interval: 500
repeat: true
onTriggered: {
messageModel.append({"mytextrole": "Line" + (counter++)})
}
}
}
There is still some jumping to the first element and jumping back down for a fraction of a second.
