Reviewer

Please comment on the following (full description):

Code Review

• Is the code of an acceptable quality?
• Does the code conform to the coding standards? Is it well structured with small focussed classes/methods/functions?
• Are there unit/system tests in place? Are the unit tests small and test the a class in isolation?
• If there are changes in the release notes then do they describe the changes appropriately?

Functional Tests

• Do changes function as described? Add comments below that describe the tests performed?
• How do the changes handle unexpected situations, e.g. bad input?
• Has the relevant documentation been added/updated?
• Is user-facing documentation written in a user-friendly manner?
• Has developer documentation been updated if required?
• Does everything look good? Comment with the ship it emoji but don't merge. A member of @mantidproject/gatekeepers will take care of it.

@FedeMPouzols I know you've seen a few issues with the old version. Would you mind testing this one?

[FedeMPouzols]

@martyngigg : sure, I'll have a look later today or tomorrow. Great that it was possible to fix these issues now!

The Python console works well as usual, both from MantidPlot and from the mantidplot script.
As for #13699, I can switch to the nbAgg backend in notebooks and I can see interactive plots (move around, zoom in/out, save (download)).

But I'm afraid this still crashes for me when I try to use tab autocompletion in the Python console of MantidPlot (as in #'13215):

(compiled in debug mode with VS 2015 Update 2, on windows 7).

@FedeMPouzols Thanks for looking at this. I'm out of ideas of what to do with this now. As we are hopefully moving to Qt 5 in the not too-distant future should we merge this anyway as it enables the web backend for the IPython notebook to work?

[FedeMPouzols]

@martyngigg: definitely yes. This change is good. I wouldn't worry much about the crash in debug mode. It seems to be a very persistent issue throughout several releases of several libraries.

This updates IPython on windows. All works well and now we can use interactive plots in notebooks (see comment above).

Thanks. I'll remove the fixes comments for those to crash issues.
