[issue23128] Key presses are doubled in Tkinter dialog invoked from window close handler (OS X only)

Philipp Emanuel Weidmann added the comment:

I upgraded to Python 2.7.9 and ActiveTcl 8.5.17.0 as suggested. I confirmed 
that this is the Tk version actually used by looking at Python's About dialog. 
The problem persists.

[issue23128] Key presses are doubled in Tkinter dialog invoked from window close handler (OS X only)

2014-12-29 Thread Philipp Emanuel Weidmann 

New submission from Philipp Emanuel Weidmann:

Minimal code example:


from Tkinter import Tk
from tkSimpleDialog import askstring

def close_handler():
askstring('', '')
root.destroy()

root = Tk()
root.protocol('WM_DELETE_WINDOW', close_handler)
root.mainloop()


Closing the main window brings up the askstring dialog. *When run on OS X* 
(Yosemite, default Python and Tkinter version), each key press on the dialog's 
input field is doubled (thus when typing abc what will actually be entered is 
aabbcc). On Linux (Python + Tkinter 2.7.8) the problem does not occur. When 
the dialog is invoked from outside the close handler, the problem does not 
occur.

This bug is causing a downstream issue in the quicksafe system 
(https://github.com/p-e-w/quicksafe/issues/2).

Ned Deily added the comment:

By default Python, do you mean the Apple supplied Python in /usr/bin? If so, it 
uses an old Apple supplied Tk 8.5. Can you reproduce the problem with the 
current python.org 2.7.9 with the current ActiveState Tk 8.5 installed?
