Okay, I am realizing that my original post was misleading about what the main
issue is. The main point I should have made is that [self delegate] is not
being allowed to handle my custom delegate methods. It is expecting a method
from NSOutlineViewDelegate. The error I am getting is....
No known instance method for selector 'outlineView:enterKetPressedForRow:'
Can I make a category on NSOutlineViewDelegate? Here's my original code with
corrected [self delegate]
--------------------------------------------------------------------
HEADER
--------------------------------------------------------------------
#import <Cocoa/Cocoa.h>
@class TKOutlineView; // lets compiler know the @interface deleration is coming
since we put @protocol before it
// delegate protocol
@protocol TKOutlineViewDelegate <NSObject> // <NSObject> because we need to use
"respondsToSelector"
@optional
-(void)outlineView:(NSOutlineView *)theOutlineView
enterKeyPressedForRow:(NSInteger)theRow;
-(void)outlineView:(NSOutlineView *)theOutlineView
deleteKeyPressedForRow:(NSInteger)theRow;
@end
@interface TKOutlineView : NSOutlineView {}
@end
--------------------------------------------------------------------
IMPLEMENTATION
--------------------------------------------------------------------
#import "TKOutlineView.h"
@implementation TKOutlineView
-(void)keyDown:(NSEvent *)theEvent
{
if ([[theEvent characters] length] == 0)
{
// dead key
return;
}
else if ([[theEvent characters] length] == 1 && [[theEvent characters]
characterAtIndex:0] == NSEnterCharacter && [[self delegate]
respondsToSelector:@selector(outlineView: enterKeyPressedForRow:)])
{
[[self delegate] outlineView:self enterKeyPressedForRow:[self
selectedRow]]; /* ERROR THIS LINE */
}
else if ([[theEvent characters] length] == 1 && [[theEvent characters]
characterAtIndex:0] == NSDeleteCharacter && [[self delegate]
respondsToSelector:@selector(outlineView: deleteKeyPressedForRow:)])
{
[[self delegate] outlineView:self deleteKeyPressedForRow:[self
selectedRow]]; /* ERROR THIS LINE */
}
else
{
[super keyDown:theEvent];
}
}
@end
How can I get [self delegate] to recognize my custom methods?
