PySide methods signature in Eclipse/WingIDE/PyCharm?

Is there any way to have the signature of the methods of PySide classes in Eclipse, WingIDE, PyCharm or any Python IDE? Currently, it auto-completes the classes and method names, but not the parameters of the methods. All functions are detected as functions without parameters.

I know it's a Python binding of a C++ framework so it's not that easy but is there any way to have the method signatures directly in 开发者_如何学Goan IDE?

I use PyDev (Eclipse plugin) and it works like a charm, also with function signatures.

EDIT:

I'm not 100% sure with C++ extensions, but it should work well if there's a Python wrapper for it. With pure C++ extensions there might be problems, but actually I haven't tried it.

Try running help(some-qt-method) in a Python console, what do you see? Exactly.

As far as I know, the only IDE that handles PyQt / PySide in depth is Eric, and only because it explicitly compiles signatures in its own format for autocompletion.
