Shiboken2: std::function or any "SLOT" type

Fabien-B

Hello,
I am trying to generate shiboken bindings for a lib that use std::function. How can I do that ?

I have this struct:

struct Callback {
    std::function<void(Peer* sender, QStringList params)> cb;
    QObject* context;
};

When I generate shiboken bindings for it, the cb field disappear, as seen in this extract of the python help:

 |  ----------------------------------------------------------------------
 |  Data descriptors defined here:
 |  
 |  context

I can modify the original library is needed, so I have two questions:

How can I generate bindings for std::function?
If this is not possible or hard to do, is there a way to declare a slot type?

Thanks

Hey,
you can check the code of existing bindings that workaround std::function arguments. You can look into the implementation of QThreadPool.start(std::function) binding, which internally accepts a PyCallable.
Here you have the change: https://codereview.qt-project.org/c/pyside/pyside-setup/+/369427
