tkhtmlview

HTML widgets for tkinter

Fork of tkhtml_widgets

Overview

This module is a collection of tkinter widgets whose text can be set in HTML format. A HTML widget isn't a web browser frame, it's only a simple and lightweight HTML parser that formats the tags used by the tkinter Text base class. The widgets behaviour is similar to the PyQt5 text widgets (see the PyQt5 HTML markup subset).

Installation

pip install tkhtmlview

Requirements

Python 3.10 or later with tcl/tk support
Pillow 11 or later
requests

Example

import tkinter as tk
from tkhtmlview import HTMLLabel
root = tk.Tk() html_label = HTMLLabel(root, html='<h1 style="color: red; text-align: center"> Hello World </H1>') html_label.pack(fill="both", expand=True) htmllabel.fitheight() root.mainloop()

You can also save html in a separate .html file and then use RenderHTML to render html for widgets.

index.html

<!DOCTYPE html>
    <html>
        <body>
            <h1>Orange is so Orange</h1>
            <img
            src="https://interactive-examples.mdn.mozilla.net/media/cc0-images/grapefruit-slice-332-332.jpg"
            />
            <p>
            The orange is the fruit of various citrus species in the family Rutaceae;
            it primarily refers to Citrus × sinensis, which is also called sweet
            orange, to distinguish it from the related Citrus × aurantium, referred to
            as bitter orange.
            </p>
        </body>
    </html>

demo.py
