Hi Alberto,
Glad to have feedback and success reports. I can't comment on the
technical questions you presented, but I thought I'd warn you that the
OpenBossa team is at the moment off, celebrating carnaval. They'll be
back online on Thursday, iff they survive the experience. :-)
Cheers,
ma.

Hi,
I'm currently working with shiboken to create a binding of a plot
facility for our sofware written in Qt/C++. Shiboken works pretty well
and it's easy to use (even though I had to add a lot of tricky and low
level code injections using typesystem files), but I have
questions/remarks about some features in Shiboken.
First of all, regarding the keywords support in Shiboken: When a C++
function uses some default arguments, shiboken introduces a keywords
dictionnary in the wrapped function. It checks that the keyword argument
is not already given by a "non-keyword" argument, but the user is not
warned if a wrong keyword was given. It would be nice for Shiboken to
throw an exception when the entered keyword is unknown; like the config
method of a Tkinter Label, for example, that throws a TclError when an
unknown option is used.
Furhermore, Shiboken takes the default value of the C++ function when
the associated keyword is not given. But, could it be possible to
implement a mechanism that allows more flexibility? For example, a way
to specify in the typesystem files a function that retrieves the
argument value to use: For a function using a Qt::Penstyle as an
argument with Qt::SolideLine as default value, we could tell shiboken to
use a C++ function that returns the current line style:
Currently generated by Shiboken: Qt::PenStyle cppArg1 = pyargs[1] ?
Shiboken::Converter<Qt::PenStyle >::toCpp(pyargs[1]) : Qt::SolidLine;
Here it would be preferable to have: Qt::PenStyle cppArg1 = pyargs[1] ?
Shiboken::Converter<Qt::PenStyle >::toCpp(pyargs[1]) :
cppself->lineStyle();
Also, regarding the documentation, is it possible to inject some doc
string inside a python function using the typesystem files, in order to
have documentation at runtime using the the "__doc__" attribute or help
function?
BTW, felicitation for the release, you did a great job!
