>This is not a GTK question, so wouldn't this be the wrong list? Anyway, your code will read in a number (using scanf) into a variable called "pos", which is overwritten by the next call to scanf. Since your list only stores pointers to "pos", you have four pointers to the same variable, which stores the last number entered by the user. Change your list to directly store the numbers themselves, or allocate new memory for each integer. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
