Question

我是tkinter的新手。我想创建主菜单，点击PLAY按钮后，它应该创建一个带有一串按钮的新窗口。此新窗口中的每个按钮都应创建另一个窗口（并关闭实际窗口）。但我的问题是，如果我点击PLAY按钮，它将打开所有窗口。

from tkinter import *


class Choices:

    def __init__(self, master):
        root.minsize(width=False, height=False)
        root['bg'] = 'forest green'
        self.master = master
        b_color = 'red'
        b_width = 30
        b_height = 4
        b_pady = 10
        self.headline = Label(self.master, text='Welcome to Casino', bg='forest green', font=('broadway', 30))
        self.headline.grid()
        self.buttons_frame = Frame(master, bg='forest green')
        self.buttons_frame.grid()
        self.b_play = Button(self.buttons_frame, text='PLAY', bg=b_color, width=b_width, height=b_height, command=self.play)
        self.b_play.grid(pady=b_pady)
        self.b_credits = Button(self.buttons_frame, text='CREDITS', bg=b_color, width=b_width, height=b_height)
        self.b_credits.grid(pady=b_pady)
        self.b_quit = Button(self.buttons_frame, text='QUIT', command=root.quit, bg=b_color, width=b_width,
                             height=b_height)
        self.b_quit.grid(pady=b_pady)

    def play(self):
        root.withdraw()
        self.pick = Toplevel(self.master)
        self.game = GamePick(self.pick)


class GamePick:

    def __init__(self, master):
        self.master = master
        self.buttons_frame = Frame(self.master)
        self.buttons_frame.grid()
        b_jack = Button(self.buttons_frame, text='Black Jack', bg='snow4', command=self.do_black_jack())
        b_jack.grid()


    def do_black_jack(self):
        root.withdraw()
        self.var_bj = Toplevel(self.master)
        self.open_bj = BlackJack(self.var_bj)


class BlackJack:

    def __init__(self, master):
        self.master = master
        label = Label(self.master, bg='green', text='It is working')
        label.grid()

root = Tk()
my = Choices(root)
root.mainloop()

解决您的问题：

在__init__()类的GamePick()中，更改以下代码行：

b_jack = Button(self.buttons_frame, text='Black Jack', bg='snow4', command=self.do_black_jack())

要：

b_jack = Button(self.buttons_frame, text='Black Jack', bg='snow4', command=self.do_black_jack)

我们所做的只是从()

中移除command = self.do_black_jack()

tkinter，多个顶级窗口
