In my application I want to let the user specify a new file name or pick an existing file which will simply be appended.
asksavefilename works to specify a new file, but it throws a warning window if an existing file is picked saying it will be overwritten.
askopenfilename lets you pick an existing file without the overwrite warning, but you can't specify a new file
Any ideas how to make either of these work or am I going to have to roll my own dialog? If I could force asksavefilename not to throw the overwrite warning, that would be great.
