want to use the existing “qtruby” ).

I have a question. Why write your own, and not use the existing one?  
Or why not modify (either just for yourself, or publish the changes  
back) qtruby for your purposes?

I imagine that writing an extension for all Qts classes might be a lot  
of work, and not something that’s too quickly done, so not reinventing  
the wheel might save you a lot of time and effort that could better be  
spent on something else.

Dear Per Christian Viken,

many Thanks for your reply.  
now my requirement is its enough to write QPainter alone.  
I don’t know how and where to start with. ( but I have done a general  
sample from the link -  
[http://www.rubyinside.com/how-to-create-a-ruby-extension-in-c-in-under-5-minutes-100.html](http://www.rubyinside.com/how-to-create-a-ruby-extension-in-c-in-under-5-minutes-100.html)  
(but inwindows)

NOTE:  
I am trying this in windows.

Regards.
