tkinter接口需要幫助

Question

我正在用tkinter開發一個圖形界面。當我打開文件，並把它，我想看看在標籤滾動指令（COMMANDE）

更準確地說我不知道​​如何將這種指令print('Sending: ' + l)該指令Label(Frame1, text="Commande", background='NavajoWhite2').pack(padx=165, pady=10)

感謝鏈接到所有

如由新穎提到

moha = Tk() 
moha.title('Emetteur G-code Universel') 
moha.geometry("2500x2500") 
moha['bg']= 'NavajoWhite2'

    fiile = filedialog.askopenfilename(filetypes=[('txt files','.txt'),('all files','.*')]) 
    file_path.set(fiile) 
    fichier = open(fiile, "r") 
    print(fiile) 

    content_bis = fichier.readlines() 

    for line in content_bis: 
      T.insert(END, line) 

    fichier.close()

，以便適當地存儲參考到窗口小部件，則應該從插件對準分離插件創建（也參見here）。

其次，在實時您的標籤在你的GUI要顯示的文字而在for循環，你將需要調用.update()主窗口上。

下面是一個Minimal, Complete, and Verifiable example，顯示這是如何工作：

import tkinter as tk 
from time import sleep 

def change_label(): 
    for i in range(5): 
     label.config(text="iteration " + str(i)) 
     # Update the GUI in real time 
     root.update() 
     sleep(1) 

root = tk.Tk() 
# Create & align a label in 2 steps 
label = tk.Label(root, text="hello") 
label.pack() 

button = tk.Button(root, text="click me", command=change_label) 
button.pack() 

# Launch the GUI 
root.mainloop()
