Re: rebuilding wx widgets with accessible addons

Hi Nathan,

I think the changed behaviour is related to this wxPython pull request:
https://github.com/wxWidgets/wxWidgets/pull/340
wxPython 4.0.7 has the old implementation where a wxWindowAccessible 
would be created where the new implementation relies on the behaviour of 
the Windows control.
I will check some things, e.g. why a slider gets the default name 
'slider' instead of the argument provided to the wxSlider constructor.

Regards,
Dietmar
