Re: Re: Gdk-Pixbuf Problem

Thanks, It worked. I declared it as a pointer and i was able to 
compile properly.
Now there is other problem.
I am using gdk_pixbuf_xlib_get_from_drawable(...) to get the
image from XDrawableArea to GdkPixbuf.
I wanted to see the values I have got in GdkPixbuf using 
workshop
(which is a graphical version of dbx), but it reported "forward 
reference _GdkPixbuf' not defined.
How can I print the contents of GdkPixbuf.

Thanks,
anita
