No matter the bad typecast, you are trying to save a NULL pointer. So what else you can expect than a segfault? And to the bad typecast. Neither of GdkPixbuf, GdkPixmap is a child of the other. See gdk_pixbuf_get_from_drawable() for how to get a GdkPixbuf from a drawable. Yeti -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing?
