如何获取另一个 Toplevel 的 Toplevel 窗口的名称？

Question

import tkinter as tk


r = tk.Tk()
r.title("root")
r.geometry("200x200")
f =tk.Frame(r)
f.pack()

top1 = tk.Toplevel(f)
top1.title("A")
#some widgets inside top2

top2 = tk.Toplevel(top1)
top2.title("B")  

print(top1.winfo_toplevel(), top1.winfo_children())

r.mainloop()

I only want to get the toplevel of top1 and nothing else ie .!frame.!toplevel.!toplevel

winfo_toplevel() returns .!frame.!toplevel

winfo_children() returns .!frame.!toplevel.!toplevel , ... all children

Answer 1

Your question is a bit unclear, but what I think you're asking is how to get top2 given only top1 .

There's no direct way to do that. You can get all of the children of top1 and then return any children that are Toplevel widgets. If you know that top1 only has a single child that is a Toplevel , you can then return the first child that is a Toplevel .

def get_toplevel(w):
    for child in w.winfo_children():
        if child.winfo_class() == "Toplevel":
            return child
    raise Exception("No toplevel window was found")
