I have an array (actually, a std::vector) of structures (actually, C++
classes) that I would like to display in an NSTableView (with each
column representing a different property of the strucutre. What would
be the best strategy to do so with Cocoa Bindings?
Seems to me that just writing controller data source methods that
fetch/store data using the C++ array would be easier.
But anyway, if you must use bindings, you might try creating an NSArray
subclass and using that in your model. In your subclass, store a
reference to the C++ array as an instance variable, and access that in
your version of the required primitive methods. NSArray is a member of
a class cluster, so subclassing is seldom recommended - as a rule of
thumb, I only do so when I'd be overriding the primitive methods
anyway, to provide a custom low-level data storage while keeping the
standard NSArray interface.
The primitive methods you need to override are listed in the NSArray &
NSMutableArray docs. If you'd like an example of an NSArray subclass
that acts as a wrapper around a "foreign" array, have a look at the
CBPerlArray class in CamelBones. Link's in my .sig.
