To get rid of the ReferenceError: systemSettings is not defined issue, you will just need set the contextproperty before loading the qml file.
And to make the ConnectSendStatisticsChanged signal work you can listen on the onClicked signal of the checkbox.
And about some way to catch the ConnectXChanged on the whole SystemSettings object.
For that I would just create a new signal and manually call that every time one of the settings changed.
This should work:

I am passing an object that is supposed to be the users settings within my app to the front end so that I can set some check boxes based on the saved settings:
In main I have
Where UserSettings are:
Strangely I get an error of
Even though the checkboxes are correctly set based on the boolean values from above. Any idea why that might be? Secondly, the
ConnectSendStatisticsChangeddoesn't detect the change at all, and I'm wondering whether its because Controller sits between qml and the System settings possibly?And lastly, I am possibly going to have alot of settings, is there a tidier way I can do a
ConnectXChangedon the whole SystemSettings object (and then save all the fields to my database) in one go, as I think i am going to have to save each one individiually which is quite large and messy when at the end of the day they are just boolean values?I added it as an example here https://github.com/amlwwalker/qml-settings-example
Thanks
