I wanted to have an object wish is derived from XfconfChannel object and
contains more data and functions to be used in my application, then i can
call the *channel_get* and *channel_set* functions by casting the object to
XfconfChannel type, just like a GtkWidget and GtkButton for example.

I'm not asking any change, if this will stay like that i'll respect the API
of xfconf ( but i rarely see the object struct and class struct defined in
the .c source), but it's not a big issue, anyway xfconf is alreay a perfect
application to use.

Note: xfconf-query gives segmentation fault if the daemon is not running.

Many thanks,
Best Regards,
Ali. ( Sorry for sending this message two times).
