[Qt-interest] QtScript, passing a var as a QString to a slot

[Jaco Naude]

Hi Rohan, Alexandre

Thanks for your replies. Both ideas sounds good. The problem is that I want
to make "generic" functions. Functions that can be used in c++ code, Qt
Script and also future script backends (Like PythonQt for example.).

I guess I can create a function for each environment from where it is called
but I am hoping to have a more generic solution. The downside of having
different functions is that it will make usage more difficult. For example,
in Qt Script environment you would need to call the QtScript function, say
AddQt. In Python you would need to call AddPython or something like that. I
guess the use of auto completion will make it easier by presenting only
AddQt in QtScript environment, and AddPython in the Python environment. But
still the best solution will be to have only 1 function.

Thanks again, if there are any ways to do this, please let me know.
