Hi,
thanks, it worked.
Another question: if my widget is put into a GtkFixed and:
gtk_container_remove(GTK_CONTAINER(window), fixed); gtk_container_add(GTK_CONTAINER (window), fixed);
then the timeout source (whose data pointer is my scrolling label) isdestroyed.Why is that?
Thanks in advance,Zoltán Böszörményi
