How does one go about taking data that has been entered in a group
of objects in a window (say, 4 Forms, 1 Button, and 1 ScrollView) and
saving them out to a file?
My current almost-working solution is to use NXWriteRootObject() and
a write method in a custom object that basically just does a [myWindow
write:myStream]. Using this method, however, I can't seem to get it to
use the correct filename...it uses the class name instead...?
Would it be better to keep the data from the window in some sort of
structure and using NXWriteType()?
I s'pose listing my code might help, but my system isn't anywhere
*near* a network, so I'd have to transcribe it by hand...
Perhaps tomorrow I'll try that...
Oh! And how the heck do you refer to individual Forms/FormCells
within a Window? I can't seem to understand how to get the id's of these
objects...I tried putting some id instance variables in my class, but I'm
not sure how it might "automagically" attach the forms to the id's in
my class (the Window id seems to do this?). This may be connected to
my filename problem, as I'm using the StringValue from one of the Forms
as my filename...or at least trying to...
Help?!?
