unfortunately I cannot do that since I am using the output for other messages

Hi all,

I have a tkinter application that uses several fonts. However only with python 2.4 when the application is closed then I get the following exceptions (with 2.6 it works Ok)

Exception exceptions.AttributeError: "'NoneType' object has no attribute 'TclError'" in <bound method Font.__del__ of <tkFont.Font instance at 0x2ac0dd4c4908>> ignored Exception exceptions.AttributeError: "'NoneType' object has no attribute 'TclError'" in <bound method Font.__del__ of <tkFont.Font instance at 0x2ac0dd4c4680>> ignored

and I have no way of capturing them since they arrive even after the last line of the program. I believe that for some reason the tkinter is deleted before and afterwards it tries to delete the fonts and creates the TclError. Is there a way to protect for these exceptions?

If you're on linux you can redirect the errors via

$ python myfile.py > mylog.txt

I'm not sure how you would catch the exceptions, though. . . . While I've become quite confused about what "that" is, Vasilis,

Unfortunately I was not able to narrow down to a simple code. All my attempts failed and they worked ok. While in the big project is not behaving correctly. The problem I see depends on the gc. If the gc deletes first the Tk_ root window then when it tries to delete the Font.__del__, tcl fails. Which for me is a bit puzzling since there is a backlink of the root in the Font class. However I saw that from python 2.6 the tkFont.Font.__del__ method has changed with respect to the 2.4 and there is a branch to catch the generic exception. When I added this to the tkFont of the 2.4 it worked and absorbed all Exceptions. Vasilis On 06/25/10 22:39, Michael Lange wrote:

I was getting the same problem with the PhotoImage() but now I am trying to delete all of them before the end of the program to avoid the exceptions. However with fonts I can miss something e.g replace a font and exit afterwards.

Can you provide a minimal code example that exhibits the problem?
