NSView’s have a method to associate an event with a context menu ( menuForEvent:). Here’s an example of how you can use this method: –zootbobbalu

some custom view

• (void)copyToPasteboard:(id)sender {NSLog(@”copyToPasteboard”);}
• (void)deleteFile:(id)sender {NSLog(@”deleteFile”);}
• (void)openInTextEdit:(id)sender {NSLog(@”openInTextEdit”);}

• (void)showInFinder:(id)sender {NSLog(@”showInFinder”);}

• (NSMenu *)menuForRightMouseDownEvent { NSDictionary *editInfo, *info; editInfo = [NSMenu infoWithTitle:@”Edit” items:@”Copy to Pasteboard/copyToPasteboard:”, @”Delete File/deleteFile:”, nil]; info = [NSMenu infoWithTitle:@”” items:editInfo, @”Open in TextEdit/openInTextEdit:”, @”Show in Finder/showInFinder:”, nil]; return [NSMenu popUpMenuWithInfo:info target:self]; }

• (NSMenu *)menuForEvent:(NSEvent *)theEvent { if ([theEvent type] == NSRightMouseDown) return [self menuForRightMouseDownEvent]; return nil; }

category addition to NSMenu to help create a quick PopUpMenu

@interface NSMenu (NSMenu_PopUpAdditions)

• (NSMenu *)popUpMenuWithInfo:(NSDictionary *)plist target:(id)target;
• (NSDictionary *)infoWithTitle:(NSString *)title items:(id)item, …; @end NSMenu (NSMenu_PopUpAdditions)

@implementation NSMenu (NSMenu_PopUpAdditions)

• (NSMenu *)popUpMenuWithInfo:(NSDictionary *)info target:(id)target { if (![info isKindOfClass:[NSDictionary class]]) return nil; NSString *title = [info objectForKey:@”title”]; NSArray *items = [info objectForKey:@”items”]; if (!title) title = @””; if (![items isKindOfClass:[NSArray class]]) return nil; NSMenu *menu = [[[NSMenu alloc] initWithTitle:title] autorelease]; NSEnumerator *itemEnum = [items objectEnumerator]; id item; while (item = [itemEnum nextObject]) { if ([item isKindOfClass:[NSDictionary class]]) { NSMenu *submenu = [self popUpMenuWithInfo:item target:target]; if (!submenu) continue; NSMenuItem *subItem = [[[NSMenuItem alloc] init] autorelease]; [subItem setTitle:[submenu title]]; [subItem setSubmenu:submenu]; [menu addItem:subItem]; } else if ([item isKindOfClass:[NSString class]]) { NSArray *comps = [item componentsSeparatedByString:@”/”]; if ([comps count] < 2) continue; NSMenuItem *menuItem = [menu addItemWithTitle:[comps objectAtIndex:0] action:NSSelectorFromString([comps lastObject]) keyEquivalent:@””]; [menuItem setTarget:target]; } } return menu; }

• (NSDictionary *)infoWithTitle:(NSString *)title items:(id)item, … { va_list ap; va_start(ap, item); id nextItem = nil; NSMutableDictionary *info = [NSMutableDictionary dictionary]; [info setValue:title forKey:@”title”]; NSMutableArray *items = [NSMutableArray array]; if (item) [items addObject:item]; while (nextItem = va_arg(ap, id)) [items addObject:nextItem]; [info setValue:items forKey:@”items”]; va_end(ap); return info; }
