There's a problem with autocompletion for PyQt4 in PyDev - when using Java 7.
When I had Java 7 (u2) installed, PyQt autocompletion for PyDev didn't work.
After typing QtGui and then dot, Eclipse got frozen for a minute and then I
got the error message:
Error connecting to python process...
I couldn't find what's the problem, I found only advices about firewall and
localhost redirection, but it didn't wok for me.
But then I uninstalled Java 7 and installed Java 6u30 and now it works well
So I think there's some problem related to Java 7.
Eclipse Indigo, PyDev 2.3.0, x64 Environment: Windows 7 Ultimate( x64), Python
3.2.2 (x64), PyQt 4.9 (x64)

Have you checked if the firewall may be blocking java 7? I.e.: you may have
given java 6 permission in the firewall but not java 7.
Anyways, right now, java 6 is recommended (java 7 is not as thoroughly tested,
but from some experiments I did, it should definitely at least work at that
level, so, it may be nice checking if the firewall could be the culprit here
-- the easy way to test that would be temporarily disabling the firewall, doing
the test and later reenabling it with the proper configuration if that was the
