Python 3.3.2 tkinter ttk TreeView per-column sorting only sorts by last column?
You should use lambda in other way. In your code every lambda gets a pointer to the same variable, that is why all functions do the same thing. You should, e.g, copy variable to make lambda unique. An example how to do it:
for each in ('name', 'path', 'time','pb'): listbox.heading(each,text=each.capitalize(),command=lambda each_=each: treeview_sort_column(listbox, each_, False))Simple example:
funcs = []for item in ('abc', 'def', 'ghi'): funcs.append(lambda : print(item))for f in funcs: f()It prints:
ghighighiBut version with fixed lambda:
funcs = []for item in ('abc', 'def', 'ghi'): funcs.append(lambda item_=item: print(item_))for f in funcs: f()prints
abcdefghi
