GdkPixbuf.PixbufDestroyNotify - NotImplementedError - python gtk3

Question

I am trying to use GdkPixbuf.Pixbuf.new_from_data() as shown in gtk 2.x and I am passing 7 arguments. But it gives me an error that I need to pass 9 arguments.

What I am doing now was working for gtk2.x . So I figured out the other 2 arguments that I need to pass.

http://developer.gimp.org/api/2.0/gdk-pixbuf/gdk-pixbuf-refcounting.html#GdkPixbufDestroyNotify

One of the arguments is of type GdkPixbuf.PixbufDestroyNotify. I don't know how to do this.

I am trying help(GdkPixbuf.PixbufDestroyNotfiy) in ipython but I am getting an error.

error: NotImplementedError.

self.img_pixbuf = GdkPixbuf.Pixbuf.new_from_data(self.img.tostring(),
                                                GdkPixbuf.Colorspace.RGB,
                                                False,
                                                self.img.depth,
                                                self.img.width,
                                                self.img.height,
                                                self.img.width*self.img.nChannels)

#Here my self.img is cv2.cv.iplimage object (OpenCV iplimage)

I am getting following error:

/home/jay/<ipython console> in <module>()

    241                 return registry[key]

    192 
    193         self.__dict__[name] = wrapper

NotImplementedError: <gi.CallbackInfo object (PixbufDestroyNotify) at 0x0x8df5b6c>

What could be the problem here ?

In PyGObject you shouldn't have to deal with DestroyNotify functions. If there is one exposed in the API, then this is a bug. You should report it to bugzilla.gnome.org.
