[QT Bug? ] Layering of custom QQuickItem-based qml item and built-in qml items

okinp

Hello,

I have a problem that I am trying to solve and I've now started to believe its a bug.
I have created an item named "Node" that is derived from QQuickItem and draws a circle.

If I do something like:

@
Item {
Rectangle {
x: 50
y: 50
width: 100
height: 100
color: "#FFFF0000"
}

Node {
    x: 100
    y: 100
    radius: 20
    color: "#FFFFCC00"
}

}
@

The Node item is drawn below the Rectangle which is not what is expected. The ordering doesn't change even if I change the z-value of the Node.

If I do something like:

@
Item {
Node{
x: 50
y: 50
radius: 100
color: "#FFFF0000"
}

    Node {
        x: 100
        y: 100
        radius: 20
        color: "#FFFFCC00"
    }
}

@
Then the expected ordering is followed.
Could this be a QT bug or am I making some silly mistake??

Thanks!

-Nik.

Interesting. What happens when you do this (reparent Node as a kid of Rectangle):
@
Rectangle {
x: 50
y: 50
width: 100
height: 100
color: "#FFFF0000"

Node {
    x: 100
    y: 100
    radius: 20
    color: "#FFFFCC00"
}

}

Trying this:

@ Rectangle {
x: 50
y: 50
width: 100
height: 100
color: "#FFFF0000"

    Node {
        x: 80
        y: 80
        radius: 20
        color: "#FFFFCC00"
    }
}

Still renders Node behind the rectangle...

Edit:
I just submitted the problem to the QT Bug Tracker: https://bugreports.qt-project.org/browse/QTBUG-31043
Hopefully this will get a high priority and will get fixed soon...
