调用 tkinter askopenfilename 方法后打开文件对话框冻结 [英] Open File Dialog freezes after tkinter askopenfilename method is called

问题描述

我试图通过 tkinter.filedialog.askopenfilename() 从用户那里简单地获取文件名.该函数返回正常，下面的代码显示文件名正常，但对话框窗口在点击打开"或取消"后不会立即关闭，它会冻结.我使用的是 python 3.3.3 或 OSX 10.9.1 和 tcl/tK 8.5.9.

I'm trying to simply get a file name from the user by tkinter.filedialog.askopenfilename(). The function returns fine and the code below displays the file name okay but the dialog window doesn't close immediately after hitting 'open' or 'cancel', it freezes. I'm using python 3.3.3 or OSX 10.9.1 and tcl/tK 8.5.9.

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

top = Tk()
top.withdraw()

file_name = filedialog.askopenfilename()

print (file_name)

推荐答案

Adding root.update() after filedialog.askopenfilename() 让打开的文件对话框关闭选择文件后.

Adding root.update() after filedialog.askopenfilename() gets the open file dialog to close after the file is chosen.

root = tk.Tk()                     
root.withdraw()
file_path = filedialog.askopenfilename()
root.update()

参考:Tkinter askopenfilename() 不会关闭
