在 Tkinter 中保存文件对话框 [英] Save File Dialog in Tkinter

问题描述

我正在用 python 实现一个基于 GUI 的文本编辑器.
我已经显示了文本区域，但是当我尝试在 Tkinter 中使用 asksaveasfile 方法时，它显示该文件已被保存，但是当我尝试在我的桌面编辑器中打开同一个文件时，它给了我一个空白文件.

I am implementing a GUI based text editor in python.
I have displayed the text area but when I try to use the asksaveasfile method in Tkinter, it shows that the file has been saved but when I try and open the same file in my desktop editor, it gives me a blank file.

仅创建并保存文件.它的内容不是.

Only, the file is created and saved. Its contents are not.

我想知道为什么.难道我做错了什么?这是我的代码:

I would like to know why. Am I doing something wrong? Here is my code:

from Tkinter import *
import tkMessageBox
import Tkinter
import tkFileDialog

def donothing():
   print "a"

def file_save():
    name=asksaveasfile(mode='w',defaultextension=".txt")
    text2save=str(text.get(0.0,END))
    name.write(text2save)
    name.close

root = Tk()
root.geometry("500x500")
menubar=Menu(root)
text=Text(root)
text.pack()
filemenu=Menu(menubar,tearoff=0)
filemenu.add_command(label="New", command=donothing)
filemenu.add_command(label="Open", command=donothing)
filemenu.add_command(label="Save", command=file_save)
filemenu.add_command(label="Save as...", command=donothing)
filemenu.add_command(label="Close", command=donothing)
filemenu.add_separator()
filemenu.add_command(label="Exit", command=root.quit)
menubar.add_cascade(label="File", menu=filemenu)

editmenu=Menu(menubar,tearoff=0)
editmenu.add_command(label="Undo", command=donothing)
editmenu.add_command(label="Copy", command=donothing)
editmenu.add_command(label="Paste", command=donothing)
menubar.add_cascade(label="Edit", menu=editmenu)

helpmenu=Menu(menubar,tearoff=0)
helpmenu.add_command(label="Help",command=donothing)
menubar.add_cascade(label="Help",menu=helpmenu)

root.config(menu=menubar)
root.mainloop()  

推荐答案

函数名是asksaveasfilename.它应该被限定为 tkFileDialog.asksaveasfilename.并且它不接受 mode 参数.

The function name is asksaveasfilename. And it should be qualified as tkFileDialog.asksaveasfilename. And it does not accept mode argument.

也许您想使用 tkFileDialog.asksaveasfile.

def file_save():
    f = tkFileDialog.asksaveasfile(mode='w', defaultextension=".txt")
    if f is None: # asksaveasfile return `None` if dialog closed with "cancel".
        return
    text2save = str(text.get(1.0, END)) # starts from `1.0`, not `0.0`
    f.write(text2save)
    f.close() # `()` was missing.
