Re: Image process in gdk



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

Thank you all!. I will try to re-read the Gtk docs following your advice
and I will look for the"Scribble" sample.
