Tkinter window open behind only window running in mainloop（仅主回路中运行的窗口后的窗口打开）

Question

我只希望“菜单”窗口在程序开始时运行，而“板”窗口在“播放”时打开按钮被按下，但是当程序启动时窗口已经在那里，按下播放按钮只会将所有功能打包到函数中。在

from Tkinter import *
menuw = Tk()
boardw = Tk()
menuw.title("menu")
menuw.configure(bg="ivory")
boardw.title("Treasure Hunt!")
boardw.configure(bg="ivory")

rows = 8 #sets the number of rows in the grid
columns = 8 # sets the number of columns in the grid
size = 75 #sets the size of each square
colour1 = "white" #sets the colour of half of the squares
colour2 = "black" #sets the colour of the other half of the squares
canvas_width = columns * size 
canvas_height = rows * size

menu()
menuw.mainloop()

Answer 1

这是因为您正在创建Tkinter的两个实例：

menuw = Tk()
boardw = Tk()

在几乎所有的情况下，您不想这样做，而是要创建一个新窗口，为您的板使用Toplevel()，并允许{}作为根窗口：

^{pr2}$

另外，这一行：Frame(boardw)没有做任何事情，因为您从未将它发送到布局管理器（pack，place，grid）来显示它。在
