[todo: convert into a gist, and cleanup post]
I’ll post discussion topics here discussing adding or changing the Menu, but I found out adding MainMenu.xib didn’t work correctly as I have thought during the discussions over on the forum.
Looking into where the menu is created I found out that GLFW3 actually creates its own default menu with only two Menus services(App menu) and Window. The code where it sets this menu up is found in cocoa_window.m over on github.
Once I figured this out I had to investigate how to edit the app or window menu. Looking over the window code, and searching through the various header files from within XCode I was able to add an item to the Window menu.
Update 2015-01-17: I’ve posted up an example project using cocos2d-x 3.3
void STDeviceMac::addMainMenu(GLViewImpl* glview)
NSWindow * appWindow = (NSWindow )glfwGetCocoaWindow(glview->getWindow());
// make your obj-c calls here
NSMenu menu = [NSApp windowsMenu];
NSMenuItem* menuItem = [[NSMenuItem alloc] initWithTitle:@"Check for Updates"
[menuItem setTarget:[SUUpdater sharedUpdater]];
NSMenuItem* menuItem = [[NSMenuItem alloc] initWithTitle:@"Steve's Test"
