在 tkinter 窗口中顯示打開文件的位置名稱

Question

很簡單，不要被代碼的大小留下深刻印象。

我想做一些非常簡單的事情（好吧，不適合我，因為我在這里尋求幫助）將打開文件的位置放在屏幕上的紅色方塊中：

屏幕

import tkinter as tk
from tkinter.filedialog import askopenfilename
from tkinter import messagebox

def OpenFile_AntiDuplicate():

    global antiduplicate_file
    mainframe = tk.Frame(bg='#1c2028')

    antiduplicate_file = askopenfilename(initialdir="/",
                        filetypes =(("Text file", "*.txt"),("All files","*.*")),
                        title = "Open text file"
                        )

    fichier_dir = tk.Label(mainframe, text=antiduplicate_file).pack()

    try:

        with open(antiduplicate_file,'r') as UseFile:
            print(antiduplicate_file)

    except:

        print("Non-existent file")


def RUN_AntiDuplicate():

    try:
        with open(antiduplicate_file,'r') as UseFile:
            print(antiduplicate_file)

    except:

        error1 = tk.messagebox.showerror("ERROR", "No files exist!")

   root.mainloop()

main_menu()

所以這是我的代碼允許您使用 3 個工具：

“拆分”/“反復制”/“合並”

目前我正在研究“反重復”，所以它在這個 Frame() 上應該顯示文本。

我已經完成了所有操作，甚至是打開文件資源管理器的按鈕，但目前文件的位置僅顯示在 cmd 中。

非常感謝！

文件的位置不會顯示，因為您在OpenFile_AntiDuplicate()創建了一個新框架來保存標簽fichier_dir並且您沒有在框架上調用任何布局函數，因此不會顯示框架。

最好在Anti_Duplicate()創建標簽fichier_dir並將其傳遞給OpenFile_AntiDuplicate()函數：

def Anti_Duplicate():
   ...    
   fichier_dir = tk.Label(mainframe, bg='#1c2028', fg='white')
   fichier_dir.place(relx=0.5, y=170, anchor='n')

   open_button = HoverButton(mainframe, font=("Arial", 10), text="Open File..",
                             background='#000000', fg='white', borderwidth=2,
                             activebackground='#202124', activeforeground='#1195cf',
                             relief='ridge', command = lambda: OpenFile_AntiDuplicate(fichier_dir))
   ...

並更新OpenFile_AntiDuplicate(...) ：

def OpenFile_AntiDuplicate(fichier_dir):
    global antiduplicate_file

    antiduplicate_file = askopenfilename(initialdir="/",
                         filetypes =(("Text file", "*.txt"),("All files","*.*")),
                         title = "Open text file"
                         )

    fichier_dir['text'] = antiduplicate_file
    ...
