輸入框和標簽未正確對齊Python 2.7 Tkinter

Question

我有以下Tkinter應用程序，該應用程序基本上可以幫助您通過在輸入框中插入新值來配置新網絡。 用戶輸入的該值使用模板保存在文件中的某個位置。 該腳本運行良好，但問題是我看到“租戶”輸入框比“網絡名稱”輸入框高。 他們的標簽也是如此。 然后，當我們單擊添加網絡並獲得另一個2輸入框時，將以非常奇怪的方式顯示。

如何對齊標簽+輸入框，如何讓它們分別顯示在標簽+輸入框的每一組中？

就像是：

租戶[入口盒]網絡[入口盒]

租戶[入口盒]網絡[入口盒]

Answer 1

以下是我為解決您的問題而編寫的簡單代碼。 您只需要將函數register（）放在您的類中，當您按下按鈕寄存器（將其放入同一個類中）時便會執行該函數。

import tkinter as tk
from tkinter import *

def register():
    username = x1.get()
    password = y1.get()
    if username!="" and password=="":
    file = open("accountfile.txt","a")
    file.write(username)
    file.write(" ")
    file.write(password)
    file.write("\n")
    file.close()

root=Tk()  

# String variables
x1=StringVar()
y1=StringVar()
Us=Entry(root,textvariable=x1)
Us.grid()
Ps=Entry(root, textvariable=y1)
Ps.grid() 

Reg=Button(root,text="Register",command=lambda:register())
Reg.grid()

root.mainloop()

要解決您的錯誤，請創建一個全局變量。 這將為文件中的所有代碼塊定義。 另外，您可以為其設置一個新值，然后在其他任何地方使用該新值

global s
s=""

def networks(self):
    with open("/home/dante/networks.yml", "w") as f:
         f.write("--- #" + "\n")
         f.write("networks:" + "\n")
         for ent in s:
             if ent:
                f.write("- { cloud: cloud1, network: "+str(ent)+ " }"+ "\n")

def render_network_field(self, network, index):
    entry_field = tk.Entry(self, textvariable=network['variable'])
    entry_field.grid(row=index, column=0, columnspan=2, padx=4, pady=6, sticky="NEWS")
    entry_field.pack()

    global s
    s=entry_field.get()

希望這可以幫助
