I like this first one. It is least verbose, and it makes the buffer 
before it makes the view, which I prefer.

If they are all legal and all correct and equivalent, go with the one 
which is easiest to read.

Pygobject style question

[Chris Green]

Having (after lots of help from here, thank you) finally converted my
Python 2, gtk 2 program to Python 3 and pygobject gtk 3 I'm left with
a couple of what might be called style questions.

I guess it's mostly down to what feels right to me but there may be
good reasons for choosing one way over another and, if so, I'd like to
know what they are.

So, my original code had:-

...
...
self.buffer = gtk.TextBuffer()
self.view = gtk.TextView(self.buffer)
...
...


This doesn't work in gtk+ 3 (or at least I don't think it does, the
converter script changed it) and there seem to be several ways of
doing it now:-

...
...
self.buffer = Gtk.TextBuffer()
self.view = Gtk.TextView(buffer = self.buffer)
...
...


...
...
self.buffer = Gtk.TextBuffer()
self.view = Gtk.TextView.new_with_buffer(self.buffer)
...
...


...
...
self.view = Gtk.TextView()
self.buffer = self.view.get_buffer()
...
...


...
...
self.view = Gtk.TextView()
self.buffer = Gtk.TextBuffer()
self.view.set_buffer(self.buffer)
...
...

Is there any reason to prefer any one of the above over the others?

Obviously the last one is a line more but lends itself to using
several Gtk.TextBuffer objects in on Gtk.TextView.
