是否可以在Tkinter中获取小部件设置?

如果我能得到下面这样的东西那就太棒了。

伪代码:

U = widget1.SettingsGet()
Print U 

打印时会返回如下内容:

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

能够获得小部件设置将非常有用。以便我可以相应地操作其他小部件。

要从cget获取小部件的所有属性,可以使用keys()获取属性,然后cget获取这些属性的值。即:

    from tkinter import *
    root=Tk()
    w=Button(root)
    for item in w.keys():
        print(item)
        print(w.cget(item))

此代码返回:

    activebackground
    systemButtonFacePressed
    activeforeground
    systemPushButtonPressedText
    anchor
    center
    background
    White
    bd
    2
    bg
    White
    bitmap

    borderwidth
    2
    command

    compound
    none
    cursor

    default
    disabled
    disabledforeground
    #a3a3a3
    fg
    systemButtonText
    font
    TkDefaultFont
    foreground
    systemButtonText
    height
    0
    highlightbackground
    White
    highlightcolor
    systemButtonFrame
    highlightthickness
    4
    image

    justify
    center
    overrelief

    padx
    12
    pady
    3
    relief
    flat
    repeatdelay
    0
    repeatinterval
    0
    state
    normal
    takefocus

    text

    textvariable

    underline
    -1
    width
    0
    wraplength
    0

空间很大>;<

在该块中,第一个是密钥,第二个是所述密钥的值。keys方法(对于所有小部件)返回所述小部件中的所有键。Config返回键及其应用于的对象(光标与光标),其中键只给出所有属性的列表。

如果您知道您需要什么设置,您可以使用cget方法获取值,例如

from Tkinter import *

root = Tk()

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

它会打印出来

Hello, world!

如果你想知道所有可用的选项,widget.config包含配置,如果你想的话,你可以创建你可能需要的设置的全部或一个子集,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:
