如果我能得到像下面这样的东西就太棒了。

伪代码:

U = widget1.SettingsGet()
Print U 

打印 U 时会返回这样的内容:

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

如果能够获取小部件设置，那将非常有用。这样我就可以相应地操作其他小部件。

最佳答案

如果您知道需要什么设置，您可以使用 cget 方法来获取值，例如

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，可以从中创建您可能需要的全部或部分设置，例如

import pprint
from Tkinter import *

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

输出:
