问题描述
Im trying to set the text of a entry object. In my app there are 3 button that when pressed show a dialogbox that provide to the user to select a directory . Im trying with the following code to set the text of the near Entry with the path that the dialogbox return. Till now I was able to print it on the console but I can't assign the string to the entry.
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.file_da_caricare = Entry( width =30, state='disabled')
self.file_log = Entry( width = 30 , state='disabled')
self.file_archive = Entry( width =30, state='disabled')
self.file_da_caricare_label = Label( text="File da caricare" )
self.file_da_caricare_label.grid(row =1 , column= 1 ,pady= 10,sticky="W")
self.file_da_caricare.grid(row =1 , column= 2 ,pady= 10)
self.file_da_caricare_button = Button(text='...',command = open_filetoupload)
self.file_da_caricare_button.grid(row =1 , column= 3 ,pady= 10,sticky="W" )
self.file_log_label = Label( text="File di log" )
self.file_log_label.grid(row =2 , column= 1 ,pady= 10,sticky="W")
self.file_log.grid(row =2 , column= 2 ,pady= 10)
self.file_log_button = Button(text='...',command = open_filelog)
self.file_log_button.grid(row =2 , column= 3 ,pady= 10,sticky="W")
self.file_archive_label = Label( text="Archivio" )
self.file_archive_label.grid(row =3 , column= 1 ,pady= 10,sticky="W")
self.file_archive = Entry( width =30)
self.file_archive.grid(row =3 , column= 2 ,pady= 10)
self.file_archive_button = Button(text='...' ,command = open_archive)
self.file_archive_button.grid(row =3 , column= 3 ,pady= 10,sticky="W")
self.scelta_test = Radiobutton(self.mioGenitore, text="Test", value='TEST')
self.scelta_test.grid(row =4 , column= 3 ,pady= 10)
self.scelta_prod = Radiobutton(self.mioGenitore, text="Prod", value='PROD')
self.scelta_prod.grid(row =5 , column= 3 ,pady= 10)
self.username_label = Label( text="Username" )
self.username_label.grid(row =6 , column= 1 ,pady= 10,sticky="W")
self.username_field = Entry( width =15)
self.username_field.grid(row =6 , column= 2 ,pady= 10,sticky="W")
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.password_label.grid(row =7, column= 1 ,pady= 10,sticky="W")
self.password_field = Entry( width =15)
self.password_field.grid(row =7 , column= 2 ,pady= 10,sticky="W")
self.send_button = Button(text='Invia',bg='blue')
self.send_button.grid(row =7 , column= 3 ,pady= 10,sticky="W")
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()
How can it possible to set the entry text ?
解决方案
插入这部分代码，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')
