Why does Qt.quit() not close the application?

[xalam]

Why does the application doesn't close when I click in it?

@import QtQuick 2.3
import QtQuick.Window 2.2

Rectangle {
visible: true
width: 360
height: 360

ListView {
   anchors.fill: parent
   id: mainList
   model: 10
   delegate:
       Rectangle {
       width: mainList.width
       height: 30
       color: (index %2 == 0) ? "white" : "lightblue"
   }
}

MouseArea {
    anchors.fill: parent
    onClicked: {
        Qt.quit();
    }
}

Text {
    text: qsTr("Hello World")
    anchors.centerIn: parent
}

}

When I click, it dispalys the message in the output

bq. Signal QQmlEngine::quit() emitted, but no receivers connected to handle it.
