tkinter destroy() not working when using tk in a class

Question

This is not my original code but you can see me trying to make sense and to expand on the code with the comments.

I was trying to figure out a way to make a quit button but all the ways I was implementing destroy() didn’t work.

#tkinter imports

        new_frame = frame_class(self)
        if self._frame is not None:

        self._frame = new_frame
        self._frame.pack()

    app.mainloop()

If anyone knows how to make a destroy button with this it would be a huge help! (:

Answer 1

Did you try it with a button press command or accessing the root_window?

button[‘command’] = root_window.destroy # give it the function

when the button is pressed the call () is done

Answer 2

You can add a button in the Application class

class Application(Tk):
    def __init__(self):
        Tk.__init__(self)
        self._frame = None
        self.switch_frame(StartMenu)
        Button(self, text='Quit', command=self.destroy).pack()
