EXC_BAD_ACCESS on currentWindow w/ latest openFrameworks (due to be 0.90)

[pkmital]

Hi Will,

I'd really love to use this in some projects I'm working on with the latest openFrameworks (due to be 0.90). I am not too familiar with how they've changed things but it definitely breaks ofxnswindower. Here is a back trace:

I also had to add some virtual methods that were not included in ofxNSWindow. I don't know if that is the right approach though. Any ideas really appreciated!

Hi Parag,

It looks like oF have started using multiple windows in the core library:

https://github.com/openframeworks/openFrameworks/blob/8138cc76ac7024ce1b06d23cbbf95517a9433c58/libs/openFrameworks/app/ofMainLoop.cpp#L43

I would recommend using this.

Hi Will, Thanks for looking into this. I didn't quite see how to easily start using nibs with their multiple window solution since they are using GLFW. ofxNSWindower would be great for this!
