在不同的窗口 tkinter 上按下按钮后如何输入文本

Question

I tried to put the text in the function itself it didn't say i was wrong but the program didn't show the text does anyone know how to solve this?

import tkinter as tk

def life1():
    newwindow = tk.Toplevel(root)
    app.title("my biography")

    texto = Label(root, text ="hello")
root = tk.Tk()

button1 = tk.Button(app,text="my life",command=life1 , padx = 80, pady = 10, bg = "green")

Answer 1

You must call pack , place , or grid on the texto label. If you want the label to show up in the new Toplevel window, the label needs to be a child of that window (eg: Label(newwindow, ...) ).

Answer 2

First of all, you have to add root.mainloop() at the end to stop the program, otherwise your program window would hang.

Second , to display the text you have to use variable.pack() so that it displays on the window.

The third and most important thing that everyone forgets is to capitalise the letter L in tk.label

`import tkinter as tk

root = tk.Tk()
root.title("first window")

def life1():
    root2 = tk.Toplevel(root)
    root2.title("my biography")

    texto = tk.Label(root2, text ="   hello    ")
    texto.pack()


button1 = tk.Button(root,text="my life",command=life1 , padx = 80, pady = 
10, bg = "green")
button1.pack()

root.mainloop()
