[guidata/guiqwt] pure python qwt

[Carlos Pascual]

Hi Pierre,

I just learned about your qwt implementation [1] from yesterday's email
in the list about PyQt5 support.

We, at the Taurus project [2] are currently discussing how to get rid of
our dependency on pyqwt5 (we have some code that is based directly on
PyQwt5 and some other based on guiqwt). Until now, the main candidate
was PyQtgraph or vispy (and there also was a proposal of working on a
pyqwt6 binding of Qwt6), but apparently you have already done much of
the work already ;)

So I have some questions:

- do you consider qwt ready for use by 3rd parties? (we do not mind it
being in beta stage, but we would mind if qwt was planned just as a
guiqwt-only library)

- are you open to contributions (e.g, us sending patches/pull-requests)?

- If so, which development model do you have in mind? Do you prefer to
keep control over the project (understandable) or are you willing to
encourage community-based development?

- regarding performance: have you compared performance of qwt to that of
PyQwt5? (at least: in your opinion, is guiqwt's footprint better now
using qwt or before using PyQwt5?)

- any feeling on how it compares performance-wise with PyQtGraph?

Sorry for so many questions, and thanks for sharing your work!

Cheers,

Carlos

email?
