Plz Help, Is that grid effect can only be apply to the whole screen???

cocos2d-x C++
#1

Am I correct that grid based effects can only be apply to the whole scene?
Is there a way to apply a grid based effect to a child node or some sprite which only occupy a small area of the screen?

I’ve been read this thread
http://www.cocos2d-iphone.org/forum/topic/29684

// inside application:didFinishLaunchingWithOptions:
EAGLView *glView = [EAGLView viewWithFrame:[window bounds] pixelFormat:kEAGLColorFormatRGBA8 depthFormat:GL_DEPTH_COMPONENT16_OES];

How can i implement this code in Cocos2d-x?

Is it possible in cocos2d-x in android ?

I did an update to version 2 and it worked fine.
