PopupMenu + alt key = hidden choices

General JUCE discussion

This can’t be used with a MenuBarComponent.

What I need is

int MenuBarComponent::getCurrentPopupIndex() const { return currentPopupIndex; }

which doesn’t exist.

I got it working when I added that function to MenuBarComponent though:
popupMenu

That’s via this:

void MenuBarUpdater::timerCallback()
{
    if( mbc != nullptr )
    {
        auto& desktop = Desktop::getInstance();
        bool isAltDown = desktop.getMainMouseSource().getCurrentModifiers().isAltDown();

        if( isAltDown != lastAltStatus )
        {
            lastAltStatus = isAltDown;
            auto currentMenuIndex = mbc->getCurrentPopupIndex();
            if( isAltDown && currentMenuIndex >= 0 )
                activeMenuIndex = currentMenuIndex;
                
            refresh();
        }
    }
}

void MenuBarUpdater::refresh()
{
    mbc->showMenu(-1); //closes current menu
    DBG( "activeMenuIndex: " << activeMenuIndex );
    mbc->showMenu(activeMenuIndex); //forces current menu to be recreated.
}

and doing this in getMenuForIndex():

        if( Desktop::getInstance().getMainMouseSource().getCurrentModifiers().isAltDown() )
        {
            menu.addSeparator();
            menu.addSubMenu("Font",
                            createFontMenu(settingsTree));
        }

CC: @t0m @jules I’ll be submitting a pull request for that MenuBarComponent index getter.
