Tkinter's Text widget has a method edit_modified()
which should return True if the modified flag of the
widget has been set, False otherwise.  It should also
be possible to pass True or False into the method to
set the flag to a desired state.  The implementation
retrieves the correct value, but then calls
self._getints( result ).  This causes an exception to
be thrown.

In my build, I found that changing the implementation
to the following appears to fix the function.

  return self.tk.call( self._w, 'edit', 'modified', arg )

Posted patch 1643641.
The patch removes the offending _getints call.

This bug still exists, I'm attaching a patch against current python-trunk.
This patch is based on the fact that documentation tk 8.4 (version which
edit command was added) and tk 8.5 says only edit_modified is supposed
to return something, which is either 0 or 1, so there was no reason to
use _gettints on that tk.call, and returning an empty tuple is against
the expected value, 0.

Hi Guilherme,

funny, I wasn't aware of this duplicate of this issue
until I got the message of your comment :)
The other duplicate is:
 http://bugs.python.org/issue1643641
which was closed by Georg Brandl upon my request.
The oldest issue is:
  http://bugs.python.org/issue961805
Both these issues have my patch attached.
(it's somewhat resembling yours and the proposition
of Ron Provost - except that it is 1.5 years older)
The latter issue also has demo code attached.

Can someone close this one or the other open issue??

Cheers,
Matthias Kievernagel

Closed as this is yet another duplicate.
