It would be great to add rope plugin autocompletion for eric6.

So here is the result of my "research":

I have tried
  - the general code, which was part of my previous messages
  - small PyQt4 application please see code:
https://github.com/spyder-ide/spyder/issues/2203
  - new style of PyQt4 signals please issue in:
https://github.com/spyder-ide/spyder/issues/2203 (in Spyder works with
rope (not with jedi)

- ----------------------------------------------------------------
IDE		general code	PyQt4	PyQt4-signals	Library
- ----------------------------------------------------------------
KDevelop	works		works	works		don't know
Spyder		works		works	works		rope
Spyder		works		works	fail		jedi
PyCharm		works		works	fail		don't know
PyDev		works		works	fail		don't know
WingIDE		works		works	fail		don't know
- ------------------------------------------------------------------

Spyder now uses both rope and jedi b/c as I read somewhere in reported
issues rope does not cope with opencv.
