All,
I'm new to Cocoa (surprise) and I'm now working on a little app, and
I've come up with a solution to an issue and I'd like some feedback on
that solution. Here's the problem description:
I have an NSTableView, bound to an NSArrayController, which is bound
to my custom object. So far so good. I can change attributes, add,
remove, all that good stuff. Now, my custom object can have one
property changed programmatically by an NSTimer. Of course, when the
change happens, the object is updated but not the NSTableView.
So, I implemented a notification in the set method for that property,
and registered a notification listener in my app controller. Now, when
the app controller sees the update to that property, it calls
reloadData method on the NSTableView. That seems to work nicely.
Except one thing: if I'm in the middle of editing a different row when
the NSTableView:reloadData method is called, the editing is ended. One
obvious way around this is to not allow in-line editing of the data in
the table, but rather in a separate set of controls for the object for
the selected row. That's where I am currently.
So, my first question is, am I missing something fundamental here? Is
this the "right" way of doing it, or is there a better way? I thought
maybe KVO might be a solution, but it didn't really seem appropriate
to this situation. I suppose you could try to manually update just the
cell, right?
My second question is more general. I've basically just completed the
Cocoa Programming book by Hillegass. Is there a "next" logical book/
document to read, or is it just time to write lots of experimental
code and ask questions?
Thanks!
jay
