我写了一个小程序，实现页面循环的滑动:

PetsModel.qml文件:

import QtQuick 2.0
ListModel {

ListElement {
name: "Polly"
type: "Parrot"
age: 12
size: "Small"
}
ListElement {
name: "Penny"
type: "Turtle"
age: 4
size: "Small"
}
}

HightRange.qml文件:

import QtQuick 2.0

Rectangle {
id: root
property int current: 0
property bool increasing: true
property int count: 0

PathView {
id: view
anchors.fill: parent
snapMode: PathView.SnapOneItem
highlightRangeMode: PathView.StrictlyEnforceRange
currentIndex: -1
model: PetsModel {id: aModel}

delegate: petDelegate
path: Path {

startX: -view.width / 2 // let the first item in left
startY: view.height / 2 // item's vertical center is the same as line's
PathLine {
relativeX: view.width * view.model.count // all items in lines
relativeY: 0
}
}

}

Component {
id: petDelegate
Item {
width: 480
height: 800

Rectangle{
anchors.fill: parent
Text {
id: first
width: parent.width
height: parent.height / 3
anchors.top:parent.top
text: name
}
Text {
id: second
anchors.top:first.bottom
width: parent.width
height: parent.height / 3
text: type
}
Text {
id: third
anchors.top:second.bottom
width: parent.width
height: parent.height / 3
text: age
}
}

MouseArea {
anchors.fill: parent
onClicked: root.current = index
}
}
}
}

main.qml文件：

import QtQuick 2.9
import QtQuick.Window 2.2

Window {
visible: true
width: 480
height: 800
title: qsTr("Hello World")
HightRange {
anchors.fill:parent
}
}

这样出来的界面上显示的信息是固定的，无法改变，我想实现界面上的信息定时改变该怎么做?例如在不滑动界面的情况下每秒age加一
