How to create a hyperlink with a Label in Tkinter?

Question

How do you create a hyperlink using a Label in Tkinter?

A quick search did not reveal how to do this. Instead there were only solutions to create a hyperlink in a Text widget.

Answer 1

Bind the label to "<Button-1>" event. When it is raised the callback is executed resulting in a new page opening in your default browser.

from tkinter import *
import webbrowser

def callback(url):
    webbrowser.open_new(url)

root = Tk()
link1 = Label(root, text="Google Hyperlink", fg="blue", cursor="hand2")
link1.pack()
link1.bind("<Button-1>", lambda e: callback("http://www.google.com"))

link2 = Label(root, text="Ecosia Hyperlink", fg="blue", cursor="hand2")
link2.pack()
link2.bind("<Button-1>", lambda e: callback("http://www.ecosia.org"))

root.mainloop()

You can also open files by changing the callback to:

webbrowser.open_new(r"file://c:\test\test.csv")

Answer 2

Alternatively if you have multiple labels and want the one function for all. That is assuming you have the link as the text

import tkinter as tk
import webbrowser

def callback(event):
    webbrowser.open_new(event.widget.cget("text"))

root = tk.Tk()
lbl = tk.Label(root, text=r"http://www.google.com", fg="blue", cursor="hand2")
lbl.pack()
lbl.bind("<Button-1>", callback)
root.mainloop()

Answer 3

There is a module on PyPi called tkhtmlview (pip install tkhtmlview) that supports HTML in tkinter. It only supports some tags, but on the page, it says that it has full support fro tags (anchor tags for hyperlinks), and supports the href attribute. It requires Python 3.4 or later with tcl/tk (tkinter) support and the Pillow 5.3.0 module. I haven't tried the tag yet, but I tried the module in general and it works.

As an example:

import tkinter as tk
from tkhtmlview import HTMLLabel

root = tk.Tk()
html_label=HTMLLabel(root, html='<a href="http://www.google.com"> Google Hyperlink </a>')
html_label.pack()
root.mainloop()

Answer 4

You can simply import webbrowser, add a function and call that inside of the button. Declare your layout manager. Here is how the code looks like:

from tkinter import *
import webbrowser

# Displaying the root window
window = Tk()
window.config(padx=100, pady=100)


# Function Declaration
def callback():
    webbrowser.open_new("https://www.google.com/")


# Button Declaration
your_variable_name = Button(text="button_name", command=callback)
your_variable_name.grid(column=2, row=3)

# keeping the Tkinter Interface running
window.mainloop()

FYI. It'll open in computer's default browser
