Re: core data - beyond the simple example

I've followed some tutorials to get started but somehow I am a bit lost when I want to do some more complex things. This might actually be more because of bindings than because of core data. Or maybe I just did not look at the right place. Maybe you guys can give me some hints links and so

Re: core data - beyond the simple example

Any thoughts on that? Yes. Remember the prerequisites I mentioned? 4 - Bindings (and probably the required KVC/KVO concepts). This means "Key Value Coding" / "Key Value Observing". Lack of proper KVO encapsulation is

Re: core data - beyond the simple example

OK ...so predicate filter I got working - sort of. I've bound the predicate in the AppDelegate to the NSArrayController. When I start up the application it filters just fine. I've also got the "add" and "remove" actions bound to buttons. But as soon as I call "add" the filtered objects re-app

> I'll give that a go, thanks. May I ask why NSImageCell? Actually, that was an incomplete thought. Using an NSImageCell would negate the need to subclass anything. You could just drag one into the appropriate column in Interface Builder, then bind the column to your color property. You can the

Re: core data - beyond the simple example

Again me not being precise enough. So IIUC the NSTableView has NSTableColumns which have NSTableCells. I would have assumed that NSTableCells is also a view - which is why I talked about views. Right now the cell is a NSTextFieldCell. I somehow need to replace that with something bigger. Somet
