单击后更新按钮的位置？ （Tkinter Python GUI）

Posted 2021-03-29

启动游戏会使按钮按随机顺序（由功能引起）但当我继续按下“正确”按钮时，按钮的位置在加载屏幕后不会更新;即使他们的文字更新。即使在randomPosition函数改变每个按钮的位置后，按钮的位置也不会更新。有没有办法更新按钮的位置，以便加载屏幕后“正确”的位置不在同一个位置？

import tkinter as tk
from tkinter import StringVar
from tkinter import *
from random import randint

f1 = ("MS Serif", 29)
lives = 3
multiplier = 0
levelCounter = 1
answer2Counter = 0
answer3Counter = 1
answer4Counter = 2

def randomPosition(): #PLACES THE BUTTONS IN RANDOM VARIETY EACH TIME GAME IS OPEN
  global xpos1, xpos2, ypos3, ypos4, random
  random = randint(1,4)
  print("Random Integer Position: " + str(random))

  #CO-ORDINATES FOR BUTTON PLACEMENT
  if random == 1:
    xpos1 = 50
    xpos2 = 730
    ypos3 = 610
    ypos4 = 720
  elif random == 2:
    xpos1 = 730
    xpos2 = 50
    ypos3 = 610
    ypos4 = 720
  elif random == 3:
    xpos1 = 50
    xpos2 = 730
    ypos3 = 720
    ypos4 = 610
  elif random == 4:
    xpos1 = 730
    xpos2 = 50
    ypos3 = 720
    ypos4 = 610

randomPosition()

  multiplier += 1

“点击后更新按钮的位置？（Tkinter Python GUI）”

这是一个最小的例子：

try:                        # In order to be able to import tkinter for
    import tkinter as tk    # either in python 2 or in python 3
except ImportError:
    import Tkinter as tk


def on_button_press(widget):
    import random
    widget_size = (widget.winfo_width(), widget.winfo_height())
    window_size = (widget.winfo_toplevel().winfo_width(),
                                    widget.winfo_toplevel().winfo_height())
    random_x = random.randint(0, window_size[0] - widget_size[0])
    random_y = random.randint(0, window_size[1] - widget_size[1])
    widget.place(x=random_x, y=random_y)


def main():
    root = tk.Tk()
    button = tk.Button(root, text="Place Randomly!")
    button['command'] = lambda w=button: on_button_press(w)
    button.place(x=0, y=0)
    tk.mainloop()

if __name__ == '__main__':
    main()
