Re: simple example of using gdk_pixbuf_new_from_file

[Muthiah Annamalai <dearestchum yahoo co in>]

Like Ive been always yapping around my tutorial,
see this http://cybernetics.freewebspace.com/gtk/
for  some tip on GdkPixbuf.

Your problem might be to change this line
> gtk_init (&argc, &argv); 
as
> gtk_init (NULL,NULL);


Cheers
Muthu.
