How to put a border around a Frame in Python Tkinter?

To put a border around a Frame in Tkinter, we have to use the highlightbackground and highlightthickeness parameters while creating the Frame. Let's take an example and see how to use these two parameters.

Steps −

• Import the tkinter library and create an instance of tkinter frame.

• Set the size of the frame using geometry method.

• Create a frame with Frame() method. Highlight the border of the frame with a color, highlightbackground="blue". Then, set the thickness of the border, highlightthickness=2.

• Next, create some widgets inside the frame. In the example, we have placed four checkbuttons and a button inside the frame.

• Finally, run the mainloop of the application window.

Example

from tkinter import *

top = Tk()
top.geometry("700x350")

frame1 = Frame(top, highlightbackground="blue", highlightthickness=2)
frame1.pack(padx=20, pady=20)

C1 = Checkbutton(frame1, text = "Music", width=200, anchor="w")
C1.pack(padx=10, pady=10)

C2 = Checkbutton(frame1, text = "Video", width=200, anchor="w")
C2.pack(padx=10, pady=10)

C3 = Checkbutton(frame1, text = "Songs", width=200, anchor="w")
C3.pack(padx=10, pady=10)

C4 = Checkbutton(frame1, text = "Games", width=200, anchor="w")
C4.pack(padx=10, pady=10)

Button(frame1, text="Button-1", font=("Calibri",12,"bold")).pack(padx=10, pady=10)

top.mainloop()

Output

It will produce the following output −

There's an easier method to create a simple border around a frame. Instead of having a Frame, create a LabelFrame and it will automatically set a border around the frame widgets.
