Re: Image process in gdk

["Luis Ramirez" <luisramirez22 gmail com>]

Problem solved! :

As I viewed first time an image with gtk_image_new_from_pixbuf,
when I tried to change that image later after pushing a button, nothing
happened, but
by using gtk_image_set_from_pixbuf instead, the image changes to the new one
(no need to use expose_event at all)

Thank you
