Newb attempt #2. So if I at least avoid using Repeater and hard
wire some Components then how do I reference any one of them
from the outside? I want to dynamically load up these "desktop"
containers with "applications" ie; the demos/declarative/rssnews
example into, say, "Desktop 2".

  Row {
    id: desk
    width: rootWidth
    height: rootHeight
    Desk { x: rootWidth * 0; deskTitle: "<h1>Desktop 1</h1>" }
    Desk { x: rootWidth * 1; deskTitle: "<h1>Desktop 2</h1>" }
    Desk { x: rootWidth * 2; deskTitle: "<h1>Desktop 3</h1>" }
    // [... * 10]
  }

// Desk.qml
import QtQuick 1.0
Rectangle {
  property alias deskTitle: title.text
  width: rootWidth
  height: rootHeight
  color: "#3f3f3f"
  Text {
    id: title
    anchors.centerIn: parent
  }
}

FWIW I switch between them like this below. I don't want to use
ListElements which are destroyed when they are out of view because
the "applications" could still be active and pulling in feeds in
the case of rssnews.

  property int current: 0

  Keys.onPressed: {
    switch(event.key) {
    case Qt.Key_Right: {
      current = (current == 9) ? 0 : current+1
      desk.x = -(rootWidth * current) } break;
    case Qt.Key_Left: {
      current = (current == 0) ? 9 : current-1
      desk.x = -(rootWidth * current) } break;
    }
  }
