How would you know when the user pressed the "x" button on the close button in a python tkinter program and do an event?
You can override the closing protocol.
def on_close():
#custom close options, here's one example:
close = messagebox.askokcancel("Close", "Would you like to close the program?")
if close:
root.destroy()
root.protocol("WM_DELETE_WINDOW", on_close)
