Is there a more elegant solution to letting the user (And programatically) toggle columns on and off?

Hm. I do have something like this. Not sure I'd call it an *elegant* solution though.

It involves subclassing NSTableView *and* NSTableColumn and it uses two private methods of NSTableView - since I couldn't get autosaving to work properly without them.

Here are the interfaces:

@interface AMRemovableColumnsTableView : NSTableView {
	IBOutlet id obligatoryColumnIdentifiers; // NSArray
	NSSet *allTableColumns;
	BOOL am_respondsToControlDidBecomeFirstResponder;
}

- (NSSet *)allTableColumns;

- (NSSet *)visibleTableColumns;

- (NSSet *)hiddenTableColumns;

- (NSSet *)obligatoryTableColumns;

- (BOOL)hideTableColumn:(NSTableColumn *)column;

- (BOOL)showTableColumn:(NSTableColumn *)column;

- (BOOL)isObligatoryColumn:(NSTableColumn *)column;

@end


@interface AMRemovableTableColumn : NSTableColumn {
	IBOutlet AMRemovableColumnsTableView *mainTableView;
}

- (AMRemovableColumnsTableView *)mainTableView; - (void)setMainTableView:(AMRemovableColumnsTableView *) newMainTableView;

- (BOOL)hidden;
- (void)setHidden:(BOOL)flag;

@end

If anyone is interested, I'm gonna write a sample app and put the code on my website.
