[Qt-qml] Loaders, Components and ListViews

[Bartosh Wroblevksy]

 So I have this little example where data of a ListElement determines what component to load in a list view something like this




ListView {

ListModel {
    id: aModel
    ListElement {
        name: "Bill Smith"
        componentID: "redRectangle"
        number: "555 3264"
    }
    ListElement {
        name: "John Brown"
        componentID:"brownRectangle"
        number: "555 8426"
    }
    ListElement {
        name: "Sam Wise"
        componentID: "yellowRectangle"
        number: "555 0473"
    }
}

    Component{
        id: redRectangle
        Rectangle{
        width: 180; height: 200
        color:"red"
        }
    }

    Component{
        id: brownRectangle
        Rectangle{
        width: 180; height: 200
        color:"brown"
        }
    }

    Component{
        id: yellowRectangle
        Rectangle{
        width: 180; height: 200
        color:"yellow"
        }
    }

    width: 180; height: 600
    model: aModel
    delegate:Loader{
        id:myLoader
        sourceComponent: (componentID == "redRectangle")? redRectangle
        : (componentID == "yellowRectangle"? yellowRectangle
        : brownRectangle)
    }
}
This all works fine and nice. But I was wondering if 
        sourceComponent: (componentID == "redRectangle")? redRectangle        : (componentID == "yellowRectangle"? yellowRectangle        : brownRectangle)
could perhaps be more generic without all the nested stuff. Something that would ideally look like this
        sourceComponent: componentID
Any input would be great. Otherwise QML is fun, fun, fun.

Thanks,Bartosh
