Tkinter: Center label in frame of fixed size?
提问by John
I am trying to create a frame of fixed size and place a text label in the center. I am not sure why this isn't working. I want the frame in the top left of the master frame, so NW is specified and that works fine. But changing the sticky direction of the label doesn't do anything. Help is appreciated.
我正在尝试创建一个固定大小的框架并在中心放置一个文本标签。我不确定为什么这不起作用。我想要主框架左上角的框架，所以指定了 NW 并且工作正常。但是改变标签的粘性方向没有任何作用。帮助表示赞赏。
self.f = Frame(self.master,bg="yellow",width=50,height=50)
self.f.grid(row=0,column=0,sticky="NW")
self.f.grid_propagate(0)
self.f.update()
self.l = Label(self.f,text="123",anchor="center",bg="yellow")
self.l.grid(column=0,row=0,sticky="wens")

You can use .place()for your label since your frame and your label have different parents. In place()you can use anchor="center"specify the startingpoint of your "anchor" with: xand y. Here is a working example:
.place()由于您的框架和标签具有不同的父级，因此您可以将其用于标签。在place()你可以使用anchor="center"指定你的“锚点”的起点：x和y。这是一个工作示例：
app = Tk()
f = Frame(app,bg="yellow",width=50,height=50)
f.grid(row=0,column=0,sticky="NW")
f.grid_propagate(0)
f.update()
l = Label(f,text="123",bg="yellow")
l.place(x=25, y=25, anchor="center")
app.mainloop()
