tkinter LabelFrame 不附加小部件 [英] tkinter LabelFrame not attatching widgets

问题描述

我在使用 tkinter 程序时遇到问题，我让 LabelFrame 对一组标签和条目进行分组，但是，它没有对我的小部件进行分组.我的 LabelFrame 代码如下:

I am running into a problem with a tkinter program, I have the LabelFrame grouping a set of labels and entries, however, it is not grouping my widgets. My code for the LabelFrame is as follows:

(我设法让标签显示，但是，它没有对我的小部件进行分组.)

(edit: i managed to get the Label to display, however, it is not grouping my widgets.)

root=Tk()
message_frame=LabelFrame(root,text="testing",padx=0,pady=0,width=100,height=100).grid(padx=5,pady=10)

message_label=Label(message_frame,text="Message").grid(row=1,column=0,sticky=W)
pub_label=Label(message_frame,text="Public Key").grid(row=2,column=0,sticky=W)
priv_label=Label(message_frame,text="Public Key").grid(row=3,column=0,sticky=W)

message_entry=Entry(message_frame,textvariable=message,width=50).grid(row=1,column=1,sticky=W)
pub_entry=Entry(message_frame,textvariable=pub_key,width=50).grid(row=2,column=1,sticky=W)
priv_entry=Entry(message_frame,textvariable=private_key,width=50).grid(row=3,column=1,sticky=W)

推荐答案

在 Tkinter 中，典型的工作流程是创建一个小部件，然后使用一些几何管理器将它放在两个单独的行上.

In Tkinter, the typical workflow is to create a widget and then place it using some geometry manager on two separate lines.

如果我没记错的话，Tkinter 小部件上的 .grid 方法返回 None.因此，如果您在创建后立即打印 message_frame，您可能会看到它是 None.当你使用传递给下一个小部件时，他们假设你想把它放在根小部件上......

If I'm not mistaken, the .grid method on Tkinter widgets returns None. So if you print message_frame right after you create it, you will probably see that it is None. When you use that passed to the next widgets, they assume you want to put it on the root widget...

简单的解决方法是执行以下操作:

The easy fix is to do something like:

message_frame=LabelFrame(root,text="testing",padx=0,pady=0,width=100,height=100)
message_frame.grid(row=0,column=0)

你可能想对所有小部件都做同样的事情，因为我怀疑你真的想要 pub_label = priv_label = None ...

And you probably want to do the same with all the widgets since I doubt you actually want pub_label = priv_label = None ...
