Just replying to say I got it working 100% as I expected, while still registering my object as a singleton! I just added a Connections element to my QML code, with the singleton object as its target. Thank you for your help, @mrjj

hi @cc672012 you may have several problems, but the first one is that you assigned a 32bit compiler to a 64bit Qt version. That will not work.

You can take a look at the "Chip" class in the 40000 chips example. Or the classes in the Drag Drop Robot example. They don't use text, but the principles are the same.
