问题描述

我正在用 Python 编写我的第一个 Tk 应用程序.我找不到如何为屏幕文本/对话框创建支持多种语言的 UI 的示例.最初我会支持英语，但希望能够添加其他语言(从文件，可能是 XML)并让用户从应用程序首选项菜单中选择他们想要的语言.

I'm writing my first Tk app with Python. I can't find an example of how to create a UI which supports multiple languages for the on screen text/dialogs. Initially I'd support English, but would like the ability to add others (from a file, perhaps XML) and have users select which language they want from an applications preferences menu.

有人对最佳方法有建议吗?

Does anyone have advice towards the best approach?

推荐答案

GUI 应使用默认语言的字符串构造其文本.因此，例如，您的代码将如下所示:

The GUI should construct its text with strings from a default language. So, for example, your code would look something like this:

import Tkinter as Tk
root = Tk.Tk()
root.title('Program')
menuButton = Tk.Button(root, text='Menu')
menuButton.grid(row=0, column=0)
root.mainloop()

更改语言就像根据所选语言修改每个 Tk 小部件一样简单.例如，

Changing the language is as simple as modifying each Tk widget depending on the selected language. For example,

def change_language(lang):
    if lang == 'English':
        root.title('Program')
        menuButton.config(text='Menu')
    elif lang == 'Spanish':
        root.title('Programa')
        menuButton.config(text='Menú')

为了更容易编写代码，您可以将语言数据存储在一个文件(例如 csv)中，将其解析为列表或字典，并具有以下内容:

To make it easier to write the code, you could store your language data in a file (e.g. csv), parse it into lists or dictionaries, and have something like this:

english = ['Program', 'Menu']
spanish = ['Programa', 'Menú']

def change_language_2(lang):
    root.title(lang[0])
    menuButton.config(text=lang[1])
