ofxNSWindower + ofxOpenCv

[ToolKid]

Hi,
when I try to use ofxNSWindower + ofxOpenCv I got EXC_BAD_ACCESS at

ofxNSWindow.mm:

//setup and display the window
[window setContentView:glview]; < -- EXC_BAD_ACCESS

OSX10.7.5 / XCODE 4.6.1

Greetings,

Getting the same error here, trying to use ofxNSWindower with ofxBox2d
@ToolKid did you manage to get yours fixed?

I'm on OSX 10.10 running XCODE 6.1

@anisharon I have tried to generate this error with ofxBox2d but I can't find it. I can't find an error with ofxOpenCv either. Everything seems to work. Could you possibly describe your error (e.g. stack trace) in more detail?

(I have added notifications so, the mouse events in ofxBox2d should work now)

@whg Thanks for getting back to me.
Here's what i have. [ typed bt in (lldb) ] Hope this helps your diagnose, it's all cryptic to me.

After having a look, I noticed a possible culprit of the EXC_BAD_ACCESS. Please can you pull and try again?

@whg it builds and runs now, but the graphics are glitchy.
Here's a screenshot,

any idea why this is happening?

Cheers.

It looks like you are drawing bits of memory that's lying around on your graphics card. Are you drawing the background in your draw function? ofxNSWindower doesn't do the hidden background drawing that the normal oF does, so you will need to call ofBackground() (or similar) yourself. If you're doing that, I'm not 100% sure what the problem is.

I have pushed a small change, removing the comment from a line that might do something, but I'm not sure if this will have any effect.

I'm not sure why you are getting such different results to me. Would it be possible for you to share a simple Xcode project that is playing up?

called ofBackground() and its working fine now.
Thanks @whg
