在本教程中，我们将介绍如何设置 Tkinter 标签的边框。
Tkinter 标签 Label 默认情况下没有边框，如下所示。
你需要分配 borderwidth 选项以在 Label 控件周围添加边框，还需要将 relief 选项分配为一个非 flat 的选项以使边框可见。
tk.Label(app,
borderwidth = 3,
relief="sunken",
text="sunken & borderwidth=3")
它将 borderwidth 设置为 3，将边框装饰选项 relief 设置为 sunken。
以下示例显示了带有不同 relief 选项的标签顺序。
如上所示，即使设置了 borderwidth，当 relief 为 flat（默认的 relief 值）时，边框也是不可见的。
完整的工作代码示例
import tkinter as tk
app = tk.Tk()
labelExample1 = tk.Label(app,
borderwidth = 1,
width = 40,
relief="raised",
text="raised & borderwidth=1")
labelExample2 = tk.Label(app,
borderwidth = 2,
width = 40,
relief="ridge",
text="ridge & borderwidth=2")
labelExample3 = tk.Label(app,
borderwidth = 3,
width = 40,
relief="sunken",
text="sunken & borderwidth=3")
labelExample4 = tk.Label(app,
borderwidth = 4,
width = 40,
relief="flat",
text="flat & borderwidth=4")
labelExample5 = tk.Label(app,
borderwidth = 5,
width = 40,
relief="groove",
text="groove & borderwidth=5")
labelExample6 = tk.Label(app,
borderwidth = 6,
width = 40,
relief="ridge",
text="solid & borderwidth=6")
labelExample1.grid(column=0, row=0, padx=10, pady=10)
labelExample2.grid(column=0, row=1, padx=10, pady=10)
labelExample3.grid(column=0, row=2, padx=10, pady=10)
labelExample4.grid(column=0, row=3, padx=10, pady=10)
labelExample5.grid(column=0, row=4, padx=10, pady=10)
labelExample6.grid(column=0, row=5, padx=10, pady=10)
app.mainloop()
