[Matplotlib-users] Qt integration and sip API

[Michele M. <mat...@gm...>]

Dear list,

I'm trying to to use matplotlib in a Qt application which needs the
sip API set to 2

	import sip
	sip.setapi('QString', 2)

However if I do this I get this error

	ImportError: cannot import name QString

I'm wondering if I'm the first to stumble upon this one, or this is a
known solution.

Below the whole Traceback.

Thanks,
Michele.
