是否可以在Tkinter中获得小部件设置？ [英] Is it possible to get widget settings in Tkinter?

问题描述

如果我能得到像下面这样的东西，这将是非常棒的。

It'd be awesome if I could get something like the below.

伪代码：

Pseudo Code:

U = widget1.SettingsGet()
Print U 

在打印时，你会返回这样的东西：

Upon printing U something like this would be returned:

widget1(background='green',foreground='grey',boarderwidth=10, relief='flat')

能够获得小部件设置。以便我可以相应地操纵其他小部件。

It would be really useful to be able to get a widgets settings. So that I can manipulate other widgets accordingly.

推荐答案

为什么您需要在单个字典中一次设置所有设置，无论如何，您必须从该设置访问特定设置字典，所以只需使用 cget 方法来获取值，例如

Why you need all the setting at once in a single dictionary, anyway you will have to access a specific setting from that settings dictionary, so instead just use cget method to get values e.g.

from Tkinter import *

root = Tk()

w = Label(root, text="Hello, world!")
w.pack()
print w.cget('text')
root.mainloop()

它会打印

Hello, world!

如果你想知道所有可用的选项，widget.config包含配置，如果你希望你可以创建你可能需要的全部或部分设置例如

If you want to know all the available options, widget.config contains the config and from that if you wish you can create all or a subset of settings which you may need e.g.

import pprint
from Tkinter import *

root = Tk()
w = Label(root, text="Hello, world!")
w.pack()
pprint.pprint(w.config())
root.mainloop()

输出：

Output:
