如何获取 Tkinter 标签文本?

问题描述：

我正在制作用户将从中选择的地址列表，并将返回地址文本.我需要使用 Tkinter.Label 因为 Tkinter.Listbox 不允许换行.

Im making a list of addresses that the user will select from, and the address text will be returned. I need to use Tkinter.Label because the Tkinter.Listbox will not allow for newlines.

关键是在 Label 类中没有类似 .get() 的方法...

The kicker is there is no .get()-like method in the Label class...

我知道我可以这样做:

v = StringVar()
Label(master, textvariable=v).pack()
v.set("New Text!")
 ...
print v.get()

但是，我有一个 5-20 个地址的列表，保留一个单独的 StringVar() 数组会很困难 b/c 我无法识别活动标签的位置.我只想访问激活的小部件内容.

However, I have a list of 5-20 address' keeping a seperate array of StringVar()'s will be difficult b/c I have no way of identifying the loc of the active label. I would like to just access the activated widget contents.

Tkinter.Label 是要使用的正确小部件吗?

Is Tkinter.Label the right widget to be using?

答

要从标签中获取值，您可以使用 cget 方法，可用于获取任何配置选项的值.

To get the value out of a label you can use the cget method, which can be used to get the value of any of the configuration options.

例如:

l = tk.Label(text="hello, world")
...
print("the label is", l.cget("text"))

您还可以将对象视为字典，将选项用作键.使用相同的示例，您可以使用 l["text"].

You can also treat the object as a dictionary, using the options as keys. Using the same example you can use l["text"].
