TkinterWeb

A fast and lightweight cross-platform webbrowser widget for Tkinter.

Overview

TkinterWeb offers bindings for the Tkhtml3 widget from http://tkhtml.tcl.tk/tkhtml.html, which enables loading HTML and CSS code into Tkinter applications.

All major operating systems running Python 3+ are supported.

Usage

TkinterWeb provides:

• a webbrowser frame to display websites in Tkinter
• a label that can display styled text, tables, and images
• a geometry manager to display Tkinter widgets and HTML elements together in a Tkinter application

TkinterWeb can be used in any Tkinter application. Here is an example:

from tkinterweb import HtmlFrame #import the HTML browser
try:
  import tkinter as tk #python3
except ImportError:
  import Tkinter as tk #python2

root = tk.Tk() #create the tkinter window
frame = HtmlFrame(root) #create the HTML browser
frame.load_website("http://tkhtml.tcl.tk/tkhtml.html") #load a website
frame.pack(fill="both", expand=True) #attach the HtmlFrame widget to the parent window
root.mainloop()

Some other tricks, such as handling page title changes, link clicks, and navigation key presses, can be found in the HtmlFrame documentation

Installation

To install TkinterWeb, simply type pip install tkinterweb in the command prompt or terminal. That's it.

Dependencies

In order to load webpages and show images, TkinterWeb requires the following packages:

• Tkinter (which is automatically packaged with most Python installations)
• PIL (can be installed via pip install pillow)
• PIL.ImageTk (may be automatically installed with PIL on some systems, otherwise needs to be installed)

Pip will automatically install PIL when installing TkinterWeb.

API documentation

TkinterWeb ships with a few classes that make it quick and easy to use.

Documentation and additional information for these classes can be found in the corresponding API refrence pages:

• TkinterWeb.HtmlFrame
• TkinterWeb.HtmlLabel

FAQs

Webpage Compatability

HTML/CSS:

• TkinterWeb supports HTML 4.01 and CSS 2.1. A full list of supported CSS declarations can be found at http://tkhtml.tcl.tk/support.html.
• Most CSS Pseudo-elements, such as :hover and :active are also supported.

JavaScript:

• Javascript is not supported at the moment.

Images:

• TkinterWeb supports nearly 50 different image types through PIL. Scalable Vector Graphic support is not as straightforward, though. In order to load SVG images:
  • PyCairo or PyGObject must be installed.
  • Either Rsvg, PyGObject, or CairoSVG must also be installed.
• Without these packages, TkinterWeb will still function properly, but SVG files will not be shown.
