[issue10731] UnicodeDecodeError in OS X tkinter when binding to MouseWheel
Dougal Graham added the comment: I recenly encuntered this error in OSX 10.9.2, using pthon 3.3 and 3.4 from Homebrew.

Ned Deily added the comment: Tcl/Tk 8.5.12 has now been released. After installing ActiveTcl 8.5.12 for OS X, your 3.2 test case that previously readily failed for me no longer does. So I hope you also find that the problem is now resolved. -- stage: - committed/rejected status: pending - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10731 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Kevin Walzer wordt...@users.sourceforge.net added the comment: I've added some comments to this on the Tkinter-dev mailing list, but to summarize, the bug is not reproducible on the Tcl side of the bridge, and so I am not clear what changes can be made in Tk's internals. It might e better to proceed with implementing a fix in Tkinter because the bug seems to occur at the level of Tkinter/Tk interaction. -- nosy: +wordtech ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10731 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10731] UnicodeDecodeError in OS X tkinter when binding to MouseWheel
Ned Deily n...@acm.org added the comment: It looks like the problem is that the current Cocoa Tcl/Tk 8.5.x returns an incorrect MouseWheel event. Using the supplied test program and breakpointing in PythonCmd (around Modules/_tkinter.c:2027 in default), I found that it is being called from Tcl for MouseWheel events with an argc of 20, which looks suspiciously like the length of argv[1], 4302153816mouse_wheel, rather than the number of arguments which should be more like 3. It may also be an issue that affects Python because _tkinter still uses the older Tcl_CreateCommand interface rather than the newer Tcl_CreateObjCommand. The same Tcl behavior is observed with Python 2.7 _tkinter.c but there the bogus arguments are translated using PyString_FromString which is unaffected by the garbage arguments. It might be possible to workaround this problem in _tkinter but the next step is to open a Tcl/Tk issue against the Cocoa implementation and push for a proper fix there. http://www.tcl.tk/man/tcl8.5/TclLib/CrtCommand.htm -- assignee: ronaldoussoren - ned.deily ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10731 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Marc Culler cul...@math.uic.edu added the comment: I am running OSX 10.5.8 on this macbook. The Tcl/Tk package on the system is ActiveState Tcl/Tk 8.4.19. I just installed Python 3.2 (r32:88452, Feb 20 2011, 10:19:59) from http://www.python.org/getit/releases/3.2/ and I am still seeing this bug. It does not occur with the Python 2.7 Tkinter package, which uses the same Tcl/Tk framework. So if it is a bug in Tk, it is harmless when used with Python 2.7. But, after all, it is not so surprising to see new UnicodeDecodeErrors when porting from Python 2 to Python 3. -- versions: +Python 3.2 -Python 3.1 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10731 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ronald Oussoren ronaldousso...@mac.com added the comment: This is almost certainly a bug in Tk. What OSX version are you using, and which python installer did you use? One thing you could try is installing a matching copy of ActiveState's Tk (8.4 for the 32-bit build, 8.5 for intel-only builds of python 2.7 and 3.2) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10731 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10731] UnicodeDecodeError in OS X tkinter when binding to MouseWheel
New submission from Marc Culler cul...@math.uic.edu:
In OS X tkinter the two-finger scroll generates MouseWheel events.
The following code:
bug.py
import tkinter
def mouse_wheel(event):
print('Mouse wheel event')
tk = tkinter.Tk()
list = tkinter.Listbox(tk)
list.bind('MouseWheel', mouse_wheel)
for n in range(20):
list.insert(tkinter.END, str(n**n))
list.pack(fill=tkinter.BOTH, expand=1)
tk.mainloop()
often throws a UnicodeDecodeError exception with a traceback like the one shown
below when you do a two-finger scroll in the window.
Traceback (most recent call last):
File bug.py, line 12, in module
tk.mainloop()
File
/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/tkinter/__init__.py,
line 1009, in mainloop
self.tk.mainloop(n)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x84 in position 1:
unexpected code byte
The value of the byte changes from time to time, and sometimes it may be
possible to scroll a few times without producing the error.
This problem did not occur on my Mandriva 2010.2 system. I think it is
specific to the Macintosh. It might possibly be related to:
