如何自动调整 tkinter 窗口的大小和居中

Question

当显示用户变量时，我在 tkinter 中调整窗口大小时遇到​​问题。由于程序采用团队的名称并稍后在程序中显示它，因此为显示窗口设置大小将不起作用，因为它需要自适应。我有让窗口居中的代码，但是有没有办法自动设置窗口的大小？

当前外观：

team_2 = t2_entry.get()
        top_2.withdraw()
        confirm_screen = Toplevel(master)
        w = 160 + len(team_2) + len(team_1)
        h = 50
        ws = confirm_screen.winfo_screenwidth()
        hs = confirm_screen.winfo_screenheight()
        x = (ws / 2) - (w / 2)
        y = (hs / 2) - (h / 2)
        confirm_screen.geometry('%dx%d+%d+%d' % (w, h, x, y))
        t1_name = Label(confirm_screen, text = "Team 1: " + team_1).grid(row = 1, column = 1)
        t2_name = Label(confirm_screen, text="Team 2: " + team_2).grid(row = 1, column = 2)
        confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = team_name_1).grid(row = 4, column = 1)
        redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)

尝试 1：

team_2 = t2_entry.get()
        top_2.withdraw()
        confirm_screen = Toplevel(master)
        w = 160 + len(team_2) + len(team_1) 
        h = 50
        ws = confirm_screen.winfo_screenwidth()
        hs = confirm_screen.winfo_screenheight()
        x = (ws / 2) - (w / 2)
        y = (hs / 2) - (h / 2)
        confirm_screen.geometry('%dx%d+%d+%d' % (w, h, x, y))
        t1_name = Label(confirm_screen, text = "Team 1: " + team_1).grid(row = 1, column = 1)
        t2_name = Label(confirm_screen, text="Team 2: " + team_2).grid(row = 1, column = 2)
        confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = team_name_1).grid(row = 4, column = 1)
        redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)

尝试 2：

team_2 = t2_entry.get()
        top_2.withdraw()
        confirm_screen = Toplevel(master)
        w = confirm_screen.winfo_width
        h = confirm_screen.winfo_height
        ws = confirm_screen.winfo_screenwidth()
        hs = confirm_screen.winfo_screenheight()
        x = (ws / 2) - (w / 2)
        y = (hs / 2) - (h / 2)
        confirm_screen.geometry('%dx%d+%d+%d' % (w, h, x, y))
        t1_name = Label(confirm_screen, text = "Team 1: " + team_1).grid(row = 1, column = 1)
        t2_name = Label(confirm_screen, text="Team 2: " + team_2).grid(row = 1, column = 2)
        confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = team_name_1).grid(row = 4, column = 1)

我想这就是你所追求的：

from tkinter import *

confirm_screen = Tk()
t1_name = Label(confirm_screen, text = "Team 1: " + "team_1").grid(row = 1, column = 1)
t2_name = Label(confirm_screen, text="Team 2: " + "team_2").grid(row = 1, column = 2)
confirm_button = Button(confirm_screen, text = "Submit", width = 10, command = None).grid(row = 4, column = 1)
redo = Button(confirm_screen, text="Redo", width=10, command= lambda: [start_team1(), clear()]).grid(row=4, column=2)

# You need to update the display so that the widgets are actually displayed on the screen.
# Otherwise `w` and `h` will both = 1
confirm_screen.update()

w = confirm_screen.winfo_width()
h = confirm_screen.winfo_height()
ws = confirm_screen.winfo_screenwidth()
hs = confirm_screen.winfo_screenheight()
x = (ws / 2) - (w / 2)
y = (hs / 2) - (h / 2)

confirm_screen.geometry('+%d+%d' % (x, y))

您必须首先放置所有小部件，然后计算窗口应该去哪里。使用<tkinter.Tk>.geometry(...)时也不需要总是包含窗口的大小。
