My goal is really to programmatically call a QML function / method, not 
bind it to a custom event. Let me provide a bit of context to clarify my 
goal:

I'm working with a C++ application (using Qt / QML), to which I have 
attached a Python interpreter, mainly for testing purposes. From that 
Python interpreter, I can access and interact with the application 
state. I would like to be able to include in these interactions the 
manipulation of the GUI, and I thought a good way to achieve this would 
be to call custom QML functions (or even existing slots such as 
`onClicked` slots of buttons).

I found some mention of similar techniques, such as in the thread 
started with 
https://www.riverbankcomputing.com/pipermail/pyqt/2014-February/033815.html, 
but couldn't get this working myself yet.

Thanks,

Stefan
