I want to do the following:
iterate over a while loop and output some text to a text widget.
sleep for one second between iterations
here's the code I tried. It doesn't like the way I am trying to make
it sleep.
i=sleeper=0
from time import sleep
name="analyzer"
while i< 100:
print "%s: This is %s time through the loop"%(name,i+1)
widget.event_generate("<<foo>>")
widget.bind("<<foo>>",lambda x=sleep, y=1:x(y))
i=i+1
I get the following error:
Traceback (innermost last):
File "c:\program files\python\lib\lib-tk\Tkinter.py", line 752, in
__call__
return apply(self.func, args)
File "C:\nick\GUI\spidergui.py", line 145, in <lambda>
widget.bind("<<foo>>",lambda x=sleep, y=1:x(y))
AttributeError: no __call__ method defined
what is the best way to do what I am trying to do?
