An NSDocument object has an NSTableview IBOutlet.
The data source of the NSTableView outlet is another object - an
NSObject object.
The NSObject object implements the data source methods - say
tableView:(NSTableView *)setObjectValue:(id) forTableColumn:
(NSTableColumn *) row:(int).
In the implementation of this data source method, I can easily
refer to the NSTableView object which comes as a parameter, but how
can I refer to the NSDocument object of which the NSTableView
object is an outlet ?
This is in order to be able to say to the NSDocument object that is
has been edited - through the data source method
tableView:setObjectValue:forTableColumn:row: - by doing something
like [theDocumentObject updateChangeCount:NSChangeDone].
If you have a NSWindowController that is the delegate of the window
in which the table view resides, you can probably do something like
this:
MyDocument *d = [[[theTableView window] delegate] document];
Another way is of course to have a reference from the table view data
source to the document itself. It would probably make sense in most
implementations.
