My code is:

import QtQuick.Window 2.2

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Text {
        id: my_text
        text: "Hello"
        font.pixelSize:  30
    }
}

Answer 1

The task is easily solved with a Timer.

import QtQuick 2.6
import QtQuick.Window 2.2

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Text {
        id: my_text
        font.pixelSize:  30
        text: "Hello"
    }

    Timer{
        id: timer
        interval: 1000
        running: true
        repeat: true
        onTriggered: my_text.opacity = my_text.opacity === 0 ? 1 : 0
     }
}
