Qt support reworked.

[datalyze-solutions]

I've rewritten the current qtpandas model and uploaded it to my pandas fork:
https://github.com/datalyze-solutions/pandas/tree/qt4/pandas/sandbox

Its still in sandbox. An example can be found in tests named TestApp.py. I just testet Qt4 and python2.7, Qt5 might be interesting.

Any reviews are welcome! 😃

[datalyze-solutions]

Test are completeted. Custom delegates are working. Ready to go! 😃

@datalyze-solutions It is easier to see/review the changes if you open a PR. But thanks for the work!

But something else, I was wondering if this part of pandas (qtpandas) wouldn't be appropriate to live as a separate project?

Not to discourage your efforts! I rather think this can be positive: not tied to the release process/schedule of pandas, encourage that some people take ownership of the project (I think there is at the moment not really a core developer who is actively maintaining this), publicize it separately, ..
And further, I think it also doesn't fully fit in the scope of core pandas.

@datalyze-solutions @rominf would you be interested in that?

live as a separate project

I second that, all enumerated reasons make sense to me.

[rominf]

Well, I actually agree with an idea to put this into separate project. I think that the vast majority of Pandas users don't need Qt bindings, moreover, the connection between those two projects is quite weak.

I propose to name it pandas-qt (Pandas is more important that the Qt in this project and people would search by pandas I think). Of course this should be uploaded to PyPi.

I haven't looked at your work, @datalyze-solutions, but it seems that rewriting everything from scratch was worth to do.

[jreback]

yep, +1 from me as well. A separate repo is worth it.

[datalyze-solutions]

Well than, I start a seperate repo named pandas-qt.
Any recommendations which licence to use?

[jreback]

lots of projects use this: https://github.com/pydata/pandas/blob/master/LICENSE
though MIT I think is ok and Apache 2.0 as well

[datalyze-solutions]

Repo is created: https://github.com/datalyze-solutions/pandas-qt

closing as qt support is now deprecated, see #9615
