Check If Window Is In Background Tkinter

So, I'm trying to make an app on tkinter. I've just started learning how this module works. In my app, I have a root window and a child (top leveled) window, and I set the child to

Solution 1:

Question: Check if window is in background

Using tk.self.winfo_containing(... you can determine if a widget, here the root window, is shown at Top Level. In this example, the center of the given window is used as visible point.

Note: While you move the window, the result may be False.

Reference: - Tkinter.Widget.winfo_containing-method

Returns the widget at the given position, or None

import tkinter as tk


classApp(tk.Tk):
    def__init__(self):
        super().__init__()

        self.is_toplevel()

    defis_toplevel(self):
        width, height, x, y = self.winfo_width(), self.winfo_height(), \
                              self.winfo_rootx(), self.winfo_rooty()

        if (width, height, x, y) != (1, 1, 0, 0):
            is_toplevel = self.winfo_containing(x + (width // 2),
                                                y + (height // 2)
                                                ) isnotNoneprint('is_toplevel: {}'.format(is_toplevel))

        self.after(2000, self.is_toplevel)


if __name__ == "__main__":
    App().mainloop()

Tested with Python: 3.5 - 'TclVersion': 8.6 'TkVersion': 8.6 - LinuxNote: Confirmed, works on Windows. May not work on MACOS.
