[pygtk] Updating a TextBuffer line by line

[diafygi at gmail.com]

Thanks John! That did the trick. I'm just about finished with a gui
for ImapGrab.

Here's my final generic code:
--------------------------
 gobject.io_add_watch(command.stdout, gobject.IO_IN | gobject.IO_HUP,
self.read_output)
....

def read_output(self, source, condition):
 if condition == gobject.IO_IN:
   line = source.readline()
   self.txtbuffer.insert_at_cursor(line)
   self.txtview.scroll_to_mark(self.txtbuffer.get_insert(), 0)
 if condition == gobject.IO_HUP:
   self.txtbuffer.insert_at_cursor("Command finished.")
   return False
 return True
--------------------------

Avast!
