How to embed some application window in my application using any Python GUI framework

Question

I want some application to look like widget inside my Python application.

That's all. I dont need any interaction between them. I'm interested in solutions in any GUI toolkit for both windows and x windows.

It would be nice to have a solution with Tkinter but it's not crucial.

Using GTK on X windows (i.e. Linux, FreeBSD, Solaris), you can use the XEMBED protocol to embed widgets using gtk.Socket. Unfortunately, the application that you're launching has to explicitly support it so that you can tell it to embed itself. Some applications don't support this. Notably, I can't find a way to do it with Firefox.

Nonetheless, here's a sample program that will run either an X terminal or an Emacs session inside a GTK window:

import os
import gtk
from gtk import Socket, Button, Window, VBox, HBox

w = Window()
e = Button("Emacs")
x = Button("XTerm")
s = Socket()
v = VBox()
h = HBox()
w.add(v)
v.add(s)
h.add(e)
h.add(x)
v.pack_start(h, expand=False)

def runemacs(btn):
    x.set_sensitive(False); e.set_sensitive(False)
    os.spawnlp(os.P_NOWAIT, "emacs", 
        "emacs", "--parent-id", str(s.get_id()))

def runxterm(btn):
    x.set_sensitive(False); e.set_sensitive(False)
    os.spawnlp(os.P_NOWAIT, "xterm",
        "xterm", "-into", str(s.get_id()))

e.connect('clicked', runemacs)
x.connect('clicked', runxterm)
w.show_all()
gtk.main()
