Qt for Python (PySide/Shiboken)

is it possible to create a new component positioned under the caller window? I have property var consoleWin: Qt.createComponent("console.qml").createObject(mainWindow, {x: mainWindow.x, y:mainWindow.x + mainWindow.height}) in mainWindow, but every time I move mainWindow, a new "consoleWin" is spawned. I don't know if something like createObject(mainWindow, {anchors.top: mainWindow.bottom}) could work
