ok, after thinking and analyzing what was going on, everytime i make
a new document in the running app, it created a new instance of the
window and all related stuff in the window including myOutlineView.
and then my dataSource in code remained the same that fills out these
outline views... (atleast this is my current understanding).
so my question now morphs into:
as Jens says below, he in some cases is looping through the apps
window list...
in my case, in my main document xib, i have an "outline Controller"
which is type NStreeController... and i have this defined..
IBOutlet NSTreeController *treeController which is the thing that is
controlling the outline view, and appears to be the thing i want to
update...
the question it appears to me is: that this "treeController" also is
made into multiple instances with each new Document, is there an
already defined "loop" of these? (a list of the open document's
NSTreeController *treeController;)
or do i need to make an NSMutableArray, and keep track of these
myself? and then update these instances myself by looping through
them?
thanks,
Jon.
