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

问题描述

如果我能得到类似下面的东西就太棒了.

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

伪代码:

U = widget1.SettingsGet()
Print U 

在打印 U 时会返回这样的内容:

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真的很有用.这样我就可以相应地操作其他小部件.

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

如果你知道你需要什么设置，你可以使用 cget 方法来获取值，例如

If you know what settings you need, you can just use the 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!

如果您想知道所有可用的选项，widget.config 包含配置，如果您愿意，您可以从中创建您可能需要的所有或部分设置，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:
