SystemTrayIconComponent OSX native menus broken in 5.00 working in 4.3.1



I’ve just returned to an unfinished project which last worked ( and was being worked on ) in JUCE version 4.3.1.

It used SystemTrayIconComponent to implement an OSX menu-extra dropdown menu and was all working fine. But in 5.00 the native code in JUCE seems to have been changed considerably and I get an assertion error as soon as the system tray icon is clicked.

in in JUCE 4.3.1 function menuNeedsUpdate() calls instance->updateMenus (menu);

but in 5.00 onwards a call is made to a new version of updateTopLevelMenu() as follows:

void updateTopLevelMenu (NSMenu* menu)
NSMenu* superMenu = [menu supermenu];
auto menuNames = currentModel->getMenuBarNames();
auto indexOfMenu = (int) [superMenu indexOfItemWithSubmenu: menu] - 1;

    removeItemRecursive (menu);

    auto updatedPopup = currentModel->getMenuForIndex (indexOfMenu, menuNames[indexOfMenu]);

    for (PopupMenu::MenuItemIterator iter (updatedPopup);;)
        addMenuItem (iter, menu, 1, indexOfMenu);

    [menu update];

but this is generating an assertion because superMenu is nil. and thus indexOfMenu. is -1 - and because of this - the subsequent MenuBarModel method getMenuForIndex() fails.

I don’t know at this stage whether this requires a bugfix from your JUCE team or whether I need to do something different. but currently I don’t see any GUI examples in your JUCE Demo app which uses native OSX menus. For the SystemTrayIcon.

This was working in Juce 4 and is now broken in 5


Hmmm strange, the JUCE demo has a DemoTaskbarComponent and it seems to work well: I can’t seem to reproduce the assertion that you are seeing.


Yes but that demo uses a JUCE menu - its a black rectangle drop-down. It doesn’t use native OSX menus at all.

But the code does ( or should ) exist in JUCE to use native menu-extras style dropdown - since I was the person who requested it ( and used it successfully until now ).


This is the code in your DemoTaskbarComponent :

void timerCallback() override

    PopupMenu m;
    m.addItem (1, "Quit the JUCE demo");

    // It's always better to open menus asynchronously when possible.
    m.showMenuAsync (PopupMenu::Options(),
                     ModalCallbackFunction::forComponent (menuInvocationCallback, this));

/////////. and this is the salient bits of mine -

void MenuExtra::timerCallback()



void SystemTrayIconComponent::showDropdownMenu (const PopupMenu& menu)
if (pimpl != nullptr)
pimpl->showMenu (menu); // this ( on 4.3 ) populates a OSX native menu using contents of ‘menu’ as template info


my code calls this - in juce_mac_SystemTrayIcon.cpp - which the Demo example doesn’t.

void showMenu (const PopupMenu& menu)
    if (NSMenu* m = createNSMenu (menu, "MenuBarItem", -2, -3, true))
        setHighlighted (true);
        [statusItem popUpStatusItemMenu: m];
        startTimer (1);


I suspect it has something to do with changes here.
This is the 5.2.1 version of menuNeedsUpdate in :

 static void menuNeedsUpdate (id self, SEL, NSMenu* menu)
            getIvar<JuceMainMenuHandler*> (self, "owner")->updateTopLevelMenu (menu);

here is the 4.xx version :

    static void menuNeedsUpdate (id, SEL, NSMenu* menu)
        if (instance != nullptr)
            instance->updateMenus (menu);
