Setting the pixel size also changes the font family

import QtQuick 1.1

Text {
    text: "bladsajdasdsadasd"
    font: fontObject.font
    QtObject {
        id: fontObject
        property alias font: textItem.font
        property Item subItem: Text {
            id: textItem
            visible: false
            font.family: "Rosewood Std Regular"
            font.pixelSize: 44

        }
    }
}

import QtQuick 1.0

MyText {
    font.pixelSize: 40
}
