PySideQwt

Hi,

Is someone working on generating a binding for Qwt library on top of PySide ?

No-one that I know of, unfortunately. I'd love to see that happening - I've always had a soft spot for data visualization! Could even reimplement "TKK Aparat":http://aparat.sourceforge.net/ with Python+Scipy+PySide+Qwt... dreaming...

Today Python is intensively used for data analysis and visualization because this is a real free alternative to MATHLAB.
Unfortunately, for now, developpers that want the power of Qt framework for building advanced UI programs with plotting features must use PyQt and PyQwt. This work very well but having a full LGPL frameworks chain will be so Cute ...

Nobody start doing this?

halida, do you want to be a volunter? :-) We will be glad to help you with any needs regarding Qwt binding generation.

I'd like to,
but I'm not familiar about how pyside/sip/python c binding works, any guidance?
I think I should check how to create python c/c++ binding first..

halida

maybe I can start from here? emmm..

We have a tutorial about this:

Qwt would be a bit more complicated due to extensive use of C++ templates in some classes.

Yeah! it works!

I simply change the tutorial to fit qwt, and it works!
current make QwtPlot & QwtCurve,
I will upload the binding project when I can make my pyqwt project run..

Nice! You can put the code on gitorious and subscribe to PySide mailing list[1] to get help, suggestions, etc.

yes, project created:
http://gitorious.org/pysideqwt#more

todo:
first import all classes,
second found a way to use numpy.array.
