Re: A kind of progress bar ?

["Nacho Martin" <newwen gmail com>]

I did sometime ago something similar for Gnomebaker.
I won't paste all the code here as it's too much. I can tell you that
I used cairo directly for the implementation, though. This way I can
have full control over the rendering.  The code is there and you can
take a look at CVS. Feel free to ask me what you don't understand.

The CVS:
http://gnomebaker.cvs.sourceforge.net/gnomebaker/gnomebaker/src/

The files:
cairofillbar.c and cairofillbar.h

Regards,

Nacho
