How do I open a website in a Tkinter window?
If you are developing a desktop application using Tkinter and you want to open a website within your application, you can do so with some simple steps.
To open a website, you need to use the web browser module in Python, which is available in Python 3. It allows you to interact with web browsers installed on your system.
In this article, we will discuss how to open a website in a new window within a Tkinter application. We will also cover some related topics, such as opening a specific URL, opening a website in an existing browser window, and making the window resizable.
Getting Started
First, you need to import the webbrowser
module, which is a standard Python module.
import webbrowser
It provides a open()
function, which we can use to open a web page. The following code will open the Python.org homepage in your default web browser.
webbrowser.open('http://python.org/')
Opening a Website in a Tkinter Window
Now that we know how to open a website using Python, let’s see how we can embed it into our Tkinter application.
To do this, we need to create a new window and add a Webview
widget to it. The Webview
widget is a built-in widget in Tkinter that allows you to display HTML content.
Python Code
import tkinter as tk
import webbrowser
from tkinter import ttk
from tkinter import *
from tkinterhtml import HtmlFrame
class Browser(Frame):
def __init__(self, master, **kw):
Frame.__init__(self, master=master, **kw)
self.grid_rowconfigure(0, weight=1)
self.grid_columnconfigure(0, weight=1)
self.html = HtmlFrame(self)
self.html.grid(row=0, sticky="nsew", padx=2, pady=2)
self.html.set_content("<html><body><h1>webpage goes here</h1></body></html>")
self.pack(expand=1, fill="both")
root = Tk()
browser = Browser(root)
browser.pack(side="top", fill="both", expand=True)
url = "http://www.google.com"
webbrowser.open(url)
root.mainloop()
Explaining the Code
In the first line, we import the tkinter
module and the webbrowser
module. The ttk
module is used to create widgets with a more modern style.
Next, we create a class called Browser
which inherits from the Frame
class. In the __init__
method, we create a new HtmlFrame
widget, which can display HTML content. We also set the row and column weights to 1 to make sure that the widget expands to fill the entire window.
In the set_content
method, we set the initial content of the HtmlFrame
to a simple HTML page that contains a heading.
We then create a new instance of the Tk
class and create a new instance of Browser
. We pack the Browser
widget into the Tk
window.
Finally, we call the open
method of the webbrowser
module and pass in the URL of the website we want to open.
Opening a Specific URL
If you want to open a specific URL instead of just the homepage of a website, you can pass the URL as a parameter to the open
function. Here’s an example:
url = "http://www.pythonforbeginners.com"
webbrowser.open(url)
Opening a Website in an Existing Browser Window
By default, the webbrowser
module opens a new browser window to display the web page. However, you may want to open the website in an existing browser window instead.
To do this, you need to set the new
parameter of the open
function to 0
. This tells the function to find an existing browser window to load the page in.
url = "http://www.pythonforbeginners.com"
webbrowser.open(url, new=0)
Making the Window Resizable
If you want to allow the user to resize the window, you can set the resizable
property of the Tk
window to True
.
root.resizable(True, True)
Conclusion
In this article, we learned how to open a website in a Tkinter window. We used the webbrowser
module to open the website in a new window and we used the HtmlFrame
widget to display the website within the Tkinter application. We also learned how to open a specific URL, open a website in an existing browser window, and make the window resizable. We hope thisarticle has been helpful to you in your Tkinter application development. With these techniques, you can make your application more user-friendly by allowing users to interact with a website without having to leave your application.
As you continue to develop your Tkinter application, you may encounter other challenges and requirements. With some research and experimentation, you can find creative solutions to these challenges and continue to improve your application. Good luck!
