How do I customize the OS X Menu Bar options in openFrameworks?

Question

Newbie question... I'm new to xcode and OpenFrameWorks, but I have experience in C++. I'm trying to add a Main Menu File to the project but it doesn't make any modification to the menu already there by default. How I tell xCode to use my MainMenu.xib instead of whatever it's using? I'm using Xcode 4.2.1 and the example openFramework app downloaded from the webpage. Thanks!!!

Currently (by default in openFrameworks 0.8.0+), openFrameworks is using GLFW for its windowing system on OS X.

GLFW doesn't load xibs/nibs, but sets up menus in the source. You can see where GLFW sets up the menu bar here:

https://github.com/glfw/glfw/blob/76afd4172727892286fe5728580021a26d198c49/src/cocoa_window.m#L738

If you would like to modify any aspect of the the Cocoa Window, GLFW offers a window handle, which is accessible in openFrameworks in the following way (this will only work on OS X of course, but native window handles are available for X11 and Windows as well):

#include <Cocoa/Cocoa.h>

// ...
NSWindow * appWindow = (NSWindow *)ofGetCocoaWindow();
if(appWindow) {
    // make your obj-c calls here
}

Also, you may need to make sure you source files are named with the .mm suffix or set up to be interpreted as objective-c++ in the project settings.

Good luck!
