Selecting a Toplevel to test using the radiobox on the right happens that if the relative Toplevel is open the function work fine, otherwise generates the following error: Exception in Tkinter callbackįile "/usr/lib/python3.7/tkinter/_init_.py", line 1705, in _call_įile "/home/bc/Desktop/simple_app.py", line 113, in on_test_exist Pressing on the first appears a mask where we can, by pressing the relevant buttons, see the execution of both the winfo_exists() method and the winfo_children() method. When you open the app, four buttons are shown. I enclose a script to better clarify what I would like to do. However, I cannot test the existence of a Toplevel by passing the name of this to winfo_exists() method. I’m trying to test the existence of a toplevel using the winfo_exists() method made available by Tkinter.
