I tried to access the wrapped gdkpixbuf inside the Gdk::Pixbuf, but i
get this, even if i #include the right header file (just to be sure):

My code looks like this:
frame_buffer = Gdk::Pixbuf::create_from_data(....);
frame_buffer->gobj()->n_channels = 4;
GdkPixbuf is an opaque structure. You are not able to access its fields
directly.
