Please help me extend my understanding of bindings...I grasp the
simple stuff, but not yet to an extent to be able to apply that to
complex situations.
In my main window (which resides in it's own nib, and is controlled by
a custom window controller), I have a combobox. I'd like to populate
the contents of that via bindings.
In my main nib file is where the controller lives that maintains the
information that I want to populate that combobox with. This
controller has a dictionary ("infoDictionary"), and the keys of that
dictionary are what I want displayed in the combobox.
My main window class has a member variable (I'm calling this
"infoController") that is a link to that information controller. So,
I attempted to set up the binding on the combobox as:
Bind to: File's Owner (which is my custom window controller)
Model Key Path: infoController.infoDictionary.allKeys
Truth be told, I didn't really expect that work (and I wasn't
disappointed), but I'm really clueless as to what *should* work.
As another stab in the dark, when I set the contents of that
dictionary, I tried wrapping that code around calls to:
[self willChangeValueForKey:@"infoController.infoDictionary.allKeys"];
<populate the dictionary here>
[self didChangeValueForKey:@"infoController.infoDictionary.allKeys"];
and that likewise didn't work; the combobox remains empty. (I also
tried throwing a "self." at the beginning of the Model Key Path to no
avail.)
I also get no output in my debugger console that might lead me to a
clue as to what I'm doing wrong.
Help, please? Thanks!
