I tried (which it isn't recommended to do) archive the object and read it back with the subclass read: method. it crashed. so how can i do this short of writing the super class in Objective-C and creating the controls? i've written a super class like that before. it was a pain to adjust matrices to fit in boxes and i never did figure out how no make a bold title for a box once it got the box's font object. (how does one do that?) 2. i need a tutorial on scroll views. i can't find any examples. i want to create a scroll view of buttons much like the digital librarian does in the summary area. could some one point me in the right direction? it is probably so easy that my simple mind doesn't see it.
