Python3和Tkinter：從函數編輯條目

Question

我試圖設置一個輸入對象的文本。 在我的應用程序中，有3個按鈕，當按下它們時，將顯示一個對話框，提供給用戶選擇目錄。 我試圖使用以下代碼來設置Near Entry的文本以及對話框返回的路徑。 到現在為止，我已經可以在控制台上打印它了，但是我無法將字符串分配給該條目。

from tkinter import *
from tkinter import filedialog
from tkinter import messagebox




class MiaApp:
    def __init__(self, genitore):

        self.mioGenitore = genitore


        def set_text(entry_obj,text):
            entry_obj.delete(0,END)
            entry_obj.insert(0,text)
            return




        def open_filetoupload():
            upload_text = filedialog.askdirectory(parent=genitore, initialdir='/')
            set_text(self.file_da_caricare,upload_text)
            print(upload_text)

        def open_filelog():
            log_text = filedialog.askdirectory(parent=genitore, initialdir='/')
            set_text(self.file_log,log_text)
            print(log_text)

        def open_archive():
            archive_text = filedialog.askdirectory(parent=genitore, initialdir='/')

            set_text(self.file_archive,archive_text)
            print(self.file_archive.text)

        self.exit_button = Button(text='Esci',command =genitore.destroy)
        self.exit_button.grid(row =6 , column= 3 ,pady= 10,sticky="W")

        self.password_label = Label( text="Password" )

        self.textArea = Text(height=2, width=30)
        self.textArea.grid(row =8 , column= 1, columnspan=1)



radice = Tk()
radice.title("DataLoader")
radice.geometry("700x400")
miaApp = MiaApp(radice)
radice.mainloop()

如何設置輸入文本？

Answer 1

插入這部分代碼，例如self.file_da_caricare

   def open_filetoupload():
        upload_text = filedialog.askdirectory(parent=genitore, initialdir='/')
        #set_text(self.file_da_caricare,upload_text)
        print(upload_text)
        self.entryText.set(upload_text)

    self.entryText = tk.StringVar()
    self.file_da_caricare = Entry( width =30, textvariable=self.entryText, state='disabled')
