Clear and print text loop

[Markkyboy]

I found some code to play with, for slicing text and displaying it like it is being typed.

It suits my needs, but I'd like the printed text to be cleared and run again repeatedly.

I've tried many different ways including another timer, but I am not getting the desired result. All suggestions welcomed.

Rectangle {
        width: 1500
        height: 100
        radius: 30
        color: "dodgerblue"
        anchors.centerIn: parent

        Text {
            id: printer

            property int i
            property string sourceText: "How to clear and loop this text once printed?"

            function type() {
                text = sourceText.slice(0, ++i);
                if (text === sourceText) printer.text = text;
            }
            font.pixelSize: 72
            anchors.centerIn: parent

            Timer {
                id: timer
                interval: 100
                repeat: true
                running: true
                onTriggered: printer.type()
            }
        }
    }

The original example is confusing. What's the difference between text and printer.text? Also, at least one error has been introduced in copying it over. The original stopped the timer when text === sourceText. The version above does not.

Here's a fixed version using an Animation:

import QtQuick 2.0

Text {
    id: printer

    property int index
    property string sourceText: "This is my special string."
    text: sourceText.slice(0, index)
    NumberAnimation on index {
        from: 0
        to: printer.sourceText.length
        loops: Animation.Infinite
        duration: 1000
    }
}

@jeremy_k - Thank you. I got tired, I got muddled. I shouldn't have posted the garbage in my original thread.
