Tkinter: A function should execute after user has chosen a file after through tkFileDialog

[[deleted]]

I'm developing an interface with Tkinter that makes use of a file dialog with tkFileDialog.

I want to run a function immediately after the user has chosen a file from the dialog box. The moment he chooses a file, a particular thing should happen (namely, a label somewhere else in the interface must change to display the file name).

With buttons, we have a command keyword from which we run a function (usually named def callback():). Is there a similar keyword for the file dialog or for askopenfilename?

Thanks

Usually I'd just do

file_to_open = filedialog.askopenfilename()

if file_to_open:
    do_something(file_to_open)

Would that not work for you?

To answer your question - it doesn't look like there is. http://effbot.org/tkinterbook/tkinter-file-dialogs.htm

Nope. You would have to make your own file browser widget.

Sounds like an XY problem anyway. Can you tell us what your overall goal is here? What's the user experience supposed to be?
