I am very new to using python and tkinter in general, but I was hoping to get some guidance on how to handle toplevel pop up exits. I have wrote a pop up that once would disable a button in the root level unless all the checkboxes in the pop up window are checked, and the close button is clicked.
However, I was wondering if there was a way to handle users "X-ing out" (closing via clicking the x icon top right corner of pop ups) instead of closing the pop via the button I made. (The button has the command .destroy() and handles toggling the status of the button on root level).
