copied!<p>I had the same need in early versions of HoudahSpot 2. I did get it working with one limitation: my code leaves the menu with square corners at the bottom.</p> <p>I have since abandonned this setup, as the BlitzSearch feature in HoudahSpot grew to need a complexer UI, I ran into other limitations with using NSViews in a NSMenu.</p> <p>Anyway, here is the original code taking care of those extra 3 pixels:</p> <pre><code>- (void)awakeFromNib { HIViewRef contentView; MenuRef menuRef = [statusMenu carbonMenuRef]; HIMenuGetContentView (menuRef, kThemeMenuTypePullDown, &contentView); EventTypeSpec hsEventSpec[1] = { { kEventClassMenu, kEventMenuCreateFrameView } }; HIViewInstallEventHandler(contentView, NewEventHandlerUPP((EventHandlerProcPtr)hsMenuCreationEventHandler), GetEventTypeCount(hsEventSpec), hsEventSpec, NULL, NULL); } #pragma mark - #pragma mark Carbon handlers static OSStatus hsMenuContentEventHandler( EventHandlerCallRef caller, EventRef event, void* refcon ) { OSStatus err; check( GetEventClass( event ) == kEventClassControl ); check( GetEventKind( event ) == kEventControlGetFrameMetrics ); err = CallNextEventHandler( caller, event ); if ( err == noErr ) { HIViewFrameMetrics metrics; verify_noerr( GetEventParameter( event, kEventParamControlFrameMetrics, typeControlFrameMetrics, NULL, sizeof( metrics ), NULL, &metrics ) ); metrics.top = 0; verify_noerr( SetEventParameter( event, kEventParamControlFrameMetrics, typeControlFrameMetrics, sizeof( metrics ), &metrics ) ); } return err; } static OSStatus hsMenuCreationEventHandler( EventHandlerCallRef caller, EventRef event, void* refcon ) { OSStatus err = eventNotHandledErr; if ( GetEventKind( event ) == kEventMenuCreateFrameView) { err = CallNextEventHandler( caller, event ); if ( err == noErr ) { static const EventTypeSpec kContentEvents[] = { { kEventClassControl, kEventControlGetFrameMetrics } }; HIViewRef frame; HIViewRef content; verify_noerr( GetEventParameter( event, kEventParamMenuFrameView, typeControlRef, NULL, sizeof( frame ), NULL, &frame ) ); verify_noerr( HIViewFindByID( frame, kHIViewWindowContentID, &content ) ); HIViewInstallEventHandler( content, hsMenuContentEventHandler, GetEventTypeCount( kContentEvents ), kContentEvents, 0, NULL ); } } return err; } </code></pre> <p>Sorry, I forgot that bit:</p> <pre><code>- (MenuRef) carbonMenuRef { MenuRef carbonMenuRef = NULL; if (carbonMenuRef == NULL) { extern MenuRef _NSGetCarbonMenu(NSMenu *); carbonMenuRef = _NSGetCarbonMenu(self); if (carbonMenuRef == NULL) { NSMenu *theMainMenu = [NSApp mainMenu]; NSMenuItem *theDummyMenuItem = [theMainMenu addItemWithTitle: @"sub" action: NULL keyEquivalent: @""]; if (theDummyMenuItem != nil) { [theDummyMenuItem setSubmenu:self]; [theDummyMenuItem setSubmenu:nil]; [theMainMenu removeItem:theDummyMenuItem]; carbonMenuRef = _NSGetCarbonMenu(self); } } } if (carbonMenuRef == NULL) { extern MenuRef _NSGetCarbonMenu2(NSMenu *); carbonMenuRef = _NSGetCarbonMenu2(self); } return carbonMenuRef; } </code></pre>
