[Qt-qml] Loading external QML files

[Martin Jones]

Another option is to have the loaded QML expose some signals that you can 
connect to.  For example if you load:

// MyItem.qml
Item {
    id: myItem
    signal closeView

    MouseArea {
        onClicked: myItem.closeView()
    }
}

using:

Loader {
    id: myLoader
    source: "MyItem.qml"
}

then you can create a connection to handle the signal:

Connections { target: myLoader.item; onCloseView: myLoader.source = "" }
