Hello, Michael.
Below is a snipped of code which I use to populate the "Recent Searches"
section of a similar NSSearchField. It works. I modified Apple's example
quite a bit.
As you can see, in my code, the menu item that is tagged with
NSSearchFieldRecentsMenuItemTag has nil action and no target. That tag makes
it a "magic" item which tells Cocoa to put the recent items there. So I think
the answer to your question of why the selector of that item never gets invoked
is that this behavior is expected. There are actually five (5) such magic
items with magic tags, which I've commented with // (*).
If I remember correctly, the way the "search" happens for a recent search is
the same as the way the search happens for a typed-in-with-keyboard search,
which is that the search field sends its action. I also had to subclass
NSSearchField to get everything working. But maybe this will get you started.
// *** Recent Searches Section
// Separator
[searchMenu insertItem:[NSMenuItem separatorItem]
atIndex:index++];
// "Recent Searches" Title Item
title = [[BkmxBasis sharedBasis] labelRecentSearches] ;
item = [[NSMenuItem alloc] initWithTitle:title
action:nil
keyEquivalent:@""];
[item setTag:NSSearchFieldRecentsTitleMenuItemTag]; // (*)
[searchMenu insertItem:item
atIndex:index++];
[item release];
// "No Recent Searches"
title = [[BkmxBasis sharedBasis] labelNoRecentSearches] ;
item = [[NSMenuItem alloc] initWithTitle:title
action:nil
keyEquivalent:@""];
[item setTag:NSSearchFieldNoRecentsMenuItemTag]; // (*)
[searchMenu insertItem:item
atIndex:index++];
[item release];
// Placeholder for the actual Recent Searches
item = [[NSMenuItem alloc] initWithTitle:title
action:nil
keyEquivalent:@""];
[item setTag:NSSearchFieldRecentsMenuItemTag]; // (*)
[searchMenu insertItem:item
atIndex:index++];
[item release];
// Separator
item = (NSMenuItem*)[NSMenuItem separatorItem];
[item setTag:NSSearchFieldRecentsTitleMenuItemTag]; // (*)
[searchMenu insertItem:item
atIndex:index++];
// Clear Recent Searches
title = [[BkmxBasis sharedBasis] labelClearRecentSearches] ;
item = [[NSMenuItem alloc] initWithTitle:title
action:nil
keyEquivalent:@""];
[item setTag:NSSearchFieldClearRecentsMenuItemTag]; // (*)
[searchMenu insertItem:item
atIndex:index++];
[item release];
