如何在新窗口Tkinter上显示文本

Question

我几周前开始在Python上学习Tkinter，并想创建一个Guess Game。但不幸的是，我遇到了一个问题，使用此代码，规则的文本(在函数rules中；text='Here are the rules...(不会出现在窗口(rule_window(上。

window = Tk()
window.title("Guessing Game")
welcome = Label(window,text="Welcome To The Guessing Game!",background="black",foreground="white")
welcome.grid(row=0,column=0,columnspan=3)
def Rules():
rule_window = Tk()
rule_window = rule_window.title("The Rules")
the_rules = Label(rule_window, text='Here are the rules...', foreground="black")
the_rules.grid(row=0,column=0,columnspan=3)
rule_window.mainloop()
rules = Button(window,text="Rules",command=Rules)
rules.grid(row=1,column=0,columnspan=1)
window.mainloop() 

有人知道如何解决这个问题吗？

Answer 1

在您的代码中，您可以将rule_window重置为字符串(在行中：rule_window = rule_window.title(...)(

试试这个：

from import tkinter *
window = Tk()
window.title("Guessing Game")
welcome = Label(window, text="Welcome To The Guessing Game!", background="black", foreground="white")
welcome.grid(row=0, column=0, columnspan=3)
def Rules():
rule_window = Toplevel(window)
rule_window.title("The Rules")
the_rules = Label(rule_window, text="Here are the rules...", foreground="black")
the_rules.grid(row=0, column=0, columnspan=3)
rules = Button(window, text="Rules", command=Rules)
rules.grid(row=1, column=0, columnspan=1)
window.mainloop()

当您希望有两个窗口同时响应时，可以使用tkinter.Toplevel()。

在您的代码中，您已经初始化了Tkinter框架的新实例，因此您可以创建一个顶级窗口，而不是。TopLevel Window通常在应用程序中创建一个弹出窗口。您也可以触发Tkinter按钮来打开新窗口。

from tkinter import *
from tkinter import ttk
#Create an instance of tkinter window
root= Tk()
root.geometry("600x450")
#Define a function
def open_new():
#Create a TopLevel window
new_win= Toplevel(root)
new_win.title("My New Window")
#Set the geometry
new_win.geometry("600x250")
Label(new_win, text="Hello There!",font=('Georgia 15 bold')).pack(pady=30)
#Create a Button in main Window
btn= ttk.Button(root, text="New Window",command=open_new)
btn.pack()
root.mainloop()
