[pygtk] How to retrieve all the content in the TextBuffer?

[ziwen]

Hi, all

I'm a newbie to pygtk. I'm writing an IM similar to MSN just for fun. I
use gtk.TextView as the GUI. I encountered an problem when trying to
retrieve what the user has input. I use get_slice, but get get_slice
only gets the text, no pixbuf or embedded image, they are replaced by
0xFFFC. I looked up the pygtk reference, still no clue to get all the
content(including pixbufs). Is there a convenient way to do that?

thanks,
