Tkinter学习笔记(一):完成文件选择和保存对话框

关键模块总结

• 导入关键包tkinter
• 打开文件：askopenfilename
• 打开多个文件：askopenfilenames
• 保存文件：asksaveasfilename

打开文件

def open_file():
    global file_path
    global file_text
    file_path = filedialog.askopenfilename(title=u'选择文件', initialdir=(os.path.expanduser('')))
    print('打开文件：', file_path)
    if file_path is not None:
        lb.config(text = "您选择的文件是："+file_path)
        with open(file=file_path, mode='r+', encoding='utf-8') as file:
            file_text = file.read()
        text1.insert('insert', file_text)

保存文件

def save_file():
    global file_path
    global file_text
    file_path = filedialog.asksaveasfilename(title=u'保存文件')
    print('保存文件：', file_path)
    lb.config(text="您保存的文件是：" + file_path)
    file_text = text1.get('1.0', tk.END)
    if file_path is not None:
        with open(file=file_path, mode='a+', encoding='utf-8') as file:
            file.write(file_text)
        text1.delete('1.0', tk.END)
        dialog.Dialog(None, {'title': 'File Modified', 'text': '保存完成', 'bitmap': 'warning', 'default': 0,
                             'strings': ('OK', 'Cancle')})
        print('保存完成')
