[PyQt] sip fails with "[CLASSNAME] has not been defined"

[tuxor1337 at web.de]

I think, I can answer my own question. But only with respect to the 
_reason_ for this behaviour. I have to admit, that I don't like this 
behaviour:

The problem is the "namespace ui". Because OnyxDialog is defined in that 
namespace, it has to be referred to as ui::OnyxDialog in 
"message_dialog.sip", even though it's being referred to in the very 
same namespace.

What I don't like about that revelation: It seems like there is no way 
to teach SIP to cut off the "ui" from the namespace. In Python, I will 
always have to refer to the classes via PyOnyx.ui.ui.MessageDialog. Of 
course, that alone is not the problem. But the problem is, that I can do 
things like "from PyOnyx.ui import ui", but not something like "from 
PyOnyx.ui.ui import *". And later, when I have a namespace called "sys", 
this is even going to conflict with the Python module of the same name.

I would love to have a module called "PyOnyx.ui" and the classes 
"MessageDialog" and "OnyxDialog" as direct parts of that module. Is 
there any possibility to achieve this with SIP 4.12.2?
