Hi,
Not sure this is the place to submit such a query, please re-direct me
to the correct place.
I implemented a simple Lights Out game which works with the old Python
2.6 (and 2.7 in Windows).
After upgrading to SUSE 13.1 which comes with Python 2.7.5 I get the
following error:
*Exception in Tkinter callback**
**Traceback (most recent call last):**
** File "/usr/lib64/python2.7/lib-tk/Tkinter.py", line 1470, in __call__**
** return self.func(*args)**
** File "./LightsOut.py", line 28, in mouse**
** grid_info = event.widget.grid_info()**
** File "/usr/lib64/python2.7/lib-tk/Tkinter.py", line 1978, in grid_info**
** self.tk.call('grid', 'info', self._w))**
**TypeError: coercing to Unicode: need string or buffer,
_tkinter.Tcl_Obj found**
*
I get the same error with Python 3.3.2 (which also comes with SUSE
13.1). I attached the source code for the game, please run with
"./LightsOut 3".
Any help would be greatly appreciated.
Thanks,
Horace
