Is QML Guaranteed to be Processed serially?

[A Former User]

I have this script:
@
import QtQuick 1.0
import FileIO 1.0
import RectData 1.0

Rectangle {
id: main
width: 360
height: 360

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

FileIO {
    id: reader
    source: "./rectangles.txt"
    onError: console.log(msg)
}

RectData {
    id: rectangles
}

 Text {
      id: mytxt
        text:"starting.."
        Component.onCompleted: {
            mytxt.text = reader.read()
            console.log (rectangles.populate(mytxt.text, width, height))
            mygrid.focus = true;
        }
 }

GridView {
    id: mygrid
    x:0
    y:0
    width: 100
    height: 100
    model: rectangles
    delegate: RectDelegate

}

}

In this QML, I want to read a txt file(C++ function rectangles.populate()) and process it before the Grid shows it. IS sequential parsing and processing guaranteed in QML? Am I implementing it correct?

QML is read first, then it's being processed in an event loop. You can't depend on that being sequential.

But if your model is done properly, the engine will detect that "rectangles" has hanged and will be updated once the changes are done.
