用小甲鱼的代码修改后运行,为什么textbox点cancel还会跳出choicebox
代码如下:
import easygui as g
import os
file_path = g.fileopenbox(default="*.txt")
with open(file_path,encoding='UTF-8') as old_file:
title = os.path.basename(file_path)
msg = "文件【%s】的内容如下:" % title
text = old_file.read()
text_after = g.textbox(msg, title, text)
if text != text_after:
# textbox 的返回值会追加一个换行符
choice = g.buttonbox("检测到文件内容发生改变,请选择以下操作:", "警告", ("覆盖保存", "放弃保存", "另存为..."))
if choice == "覆盖保存":
with open(file_path, "w",encoding='UTF-8') as old_file:
old_file.write(text_after)
if choice == "放弃保存":
pass
if choice == "另存为...":
another_path = g.filesavebox(default=".txt")
if os.path.splitext(another_path)[1] != '.txt':
another_path += '.txt'
with open(another_path, "w",encoding='UTF-8') as new_file:
new_file.write(text_after)
因为点Cancle的返回值是None,当然不等于原文件内容啦
这样改就是了:
- import easygui as g
- import os
- file_path = g.fileopenbox(default="*.txt")
- with open(file_path,encoding='UTF-8') as old_file:
- title = os.path.basename(file_path)
- msg = "文件【%s】的内容如下:" % title
- text = old_file.read()
- text_after = g.textbox(msg, title, text)
- if not text_after:
- text_after = text
- if text != text_after:
- # textbox 的返回值会追加一个换行符
- choice = g.buttonbox("检测到文件内容发生改变,请选择以下操作:", "警告", ("覆盖保存", "放弃保存", "另存为..."))
- if choice == "覆盖保存":
- with open(file_path, "w",encoding='UTF-8') as old_file:
- old_file.write(text_after)
- if choice == "放弃保存":
- pass
- if choice == "另存为...":
- another_path = g.filesavebox(default=".txt")
- if os.path.splitext(another_path)[1] != '.txt':
- another_path += '.txt'
- with open(another_path, "w",encoding='UTF-8') as new_file:
- new_file.write(text_after)
