The docs are out of date.  If you check out the example, you'll see it
should be:

    AnchorChanges {
        target: rectangle15
        anchors.bottom: undefined
        anchors.left: image4.left
        anchors.top:homebar.top
    }

The margins can be changed using the PropertyChanges{} element.

Cheers,

Aaron
