按下按钮时如何更新变量？

  • 772

有一个功能OpenWin1()可以打开一个带有设置的窗口，您可以在其中输入坐标、尺寸等（到目前为止我只完成了坐标）。
单击时，会在另一个文件中创建一行包含设置的内容。

一切正常，一切都很好，但变量没有更新，采用默认文本（pos Y, pos X）。

我们需要确保当按下按钮时，"Update"变量会被更新。

import tkinter as tk
from tkinter import ttk
import subprocess
import time
from tkinter import *

root = Tk()
root.title('123')
root.geometry('400x600')
root.resizable(width=False, height=False)

font = ('intro.otf', 12)

def Insert(file_name, text_line, text_to_add):
    with open(file_name, 'r', encoding='utf-8') as read_file:
        text = read_file.readlines()
        text.insert(text_line, text_to_add+"\n")
    with open(file_name, 'w', encoding='utf-8') as write_file:
        for i in text:
            write_file.write(i)
    with open(r"game.py", 'r') as fp:
        for count, line in enumerate(fp):
            pass

def OpenWin1():
    Win1 = Tk()
    Win1.title('Setup gameobject')
    Win1.geometry('220x200')
    Win1.resizable(width=False,height=False)
    WB1 = Button(Win1,text='Add gameobject',command=lambda:Insert("game.py", 24, f'    pygame.draw.rect(screen, WHITE, ({Xprint}, {Yprint}, 75, 75))'), font=font)
    WB1.place(y=10,x=40)
    #Yprint
    info_Tf = Entry(Win1)
    info_Tf.insert(END, 'Pos Y')
    info_Tf.place(y=120,x=40)
    #Xprint
    info_Tf2 = Entry(Win1)
    info_Tf2.insert(END, 'Pos X')
    info_Tf2.place(y=100,x=40)
    Yprint = info_Tf.get()
    Xprint = info_Tf2.get()
    Win1.mainloop()

btn1 = Button(root, text='Add Rect(Game Object)', command=lambda:OpenWin1())
btn1.place(x=0, y=0)

root.mainloop()

我需要将输入字段中写入的内容写入变量。出现这种情况，但是并没有更新，而是一开始就只写了一次。

重要的！如果要运行此代码，请在与此代码相同的文件夹中创建一个game.py文件。

    作为一个选项：

    from tkinter import *


root = Tk()
root.title('123')
root.geometry('400x600')
root.resizable(width=False, height=False)

font = ('intro.otf', 12)

# -----------------------------> vvvvvvv  vvvvvvvv <-------------------------
def Insert(file_name, text_line, info_Tf, info_Tf2):           # text_to_add):
    text_to_add = f'    pygame.draw.rect(screen, WHITE, ({info_Tf2.get()}, '\
                  f'{info_Tf.get()}, 75, 75))'
    print(f'{text_to_add}\n')

    with open(file_name, 'r', encoding='utf-8') as read_file:
        text = read_file.readlines()
        text.insert(text_line, text_to_add + "\n")
    with open(file_name, 'w', encoding='utf-8') as write_file:
        for i in text:
            write_file.write(i)
    with open(r"game.py", 'r') as fp:
        for count, line in enumerate(fp):
            pass

def openWin1():
    win1 = Tk()
    win1.title('Setup gameobject')
    win1.geometry('220x200')
    win1.resizable(width=False, height=False)

    wB1 = Button(win1,

# -------------------------------------------> vvvvvvv  vvvvvvvv <---------------- # +++
        command=lambda: Insert("game.py", 24,  info_Tf, info_Tf2),
        font=font)
    wB1.place(y=10, x=40)

    #Yprint
    info_Tf = Entry(win1)
    info_Tf.insert(END, 'Pos Y')
    info_Tf.place(y=120, x=40)
    #Xprint
    info_Tf2 = Entry(win1)
    info_Tf2.insert(END, 'Pos X')
    info_Tf2.place(y=100, x=40)
    Yprint = info_Tf.get()
    Xprint = info_Tf2.get()
#?   Win1.mainloop()


btn1 = Button(root, text='Add Rect(Game Object)', 
#?   command=lambda: OpenWin1())
    command=openWin1)
btn1.place(x=0, y=0)

root.mainloop()
