Hi
I need to use a NSTableView to control data input by the user. The
table has two columns, labeled "Title" and "Content". The number of
columns is fixed.
I've read what I can find on the internet, but a lot of it goes way
over my head (I'm fairly new at ObjC and xCode -- coming from Java).
I understand (from assorted hints I've seen online) that one may use a
NSDictionaryController to handle data input/output/display/saving etc
from a table.
I really have no idea how to do this, and haven't found a tutorial
that speaks to my tiny brain.
I was hoping one of you Cocoa masters would have a tip or two?
This is what I've got:
a bunch of code that works (it creates html for a webpage based on
user selection/input). a NSTextArea, NSTextField and NSTableView that
are currently inert.
A NSDictionaryController sitting idle.
I want it to store data in key(title)value(content) pairs. Initially
there are no key/vals, until the user creates a new entry. This
should be handled by a little '+' button that I've placed below the
NSTableview. Removal of the entries should be handled buy the '-'
button at its side.
I feel confident that I could do all this, if I had any idea where to
start. How do I "link" the NSDict... to my *.m *.h files so that I
can save/load/ otherwise manipulate the data? How do I shove data
into the nsdict....? Is it even an instance of nsdictionary? Do I
need to make an NSMutableDictionary and somehow introduce them to each
other?
Any help would be appreciated, I'm stuck in a bit of a hole here.
Thanks,
Mike
