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.

The GdkPixbuf *is* a private structure, so it's ok that the file is not installed. You reference a GdkPixbuf by its pointer, so you don't need the actual structure layout. How are you trying to use it? Sounds like you're trying to malloc() a GdkPixbuf or allocate it in the stack. You can't do these things. A GdkPixbuf is a ref counted object, which you
create using functions like gdk_pixbuf_new().
