Here's a snippet I have laying around. It doesn't exactly do what you
ask, but maybe it's a starting point. You might see what the cited sf
tracker item is about as well.
# Print Tk errors to stdout. python.org/sf/639266
import Tkinter
OldTk = Tkinter.Tk
class Tk(OldTk):
def __init__(self, *args, **kw):
OldTk.__init__(self, *args, **kw)
self.tk.createcommand('tkerror', self.tkerror)
def tkerror(self, arg):
print "TCL error in asynchronous code:"
print self.tk.call("set", "errorInfo")
Tkinter.Tk = Tk
