There's one easy way that may do what you want - make your own
Tkinter.mainloop()
You can roll your own event loop using Tkinter's dooneevent
TCL_ALL_EVENTS = 0
while self.exit < 0:
self.root.tk.dooneevent(TCL_ALL_EVENTS)
except SystemExit:
#print 'Exit'
self.exit = 1
break
...
This has the added advantage of avoiding the 20msec. sleep in the
_tkinter mainloop C code (a big bug IMHO).
For a more complete example of this mainloop replacement, see
the CVS version of python/Demo/tix/tixwidgets.py - the mainloop/quit
code is not Tix specific.
