WebAppify
=========
WebAppify is a simple module to easily create your own desktop apps of websites. WebAppify uses PyQt5 and QtWebKit or
QtWebEngine for displaying the web page, and works on Python 2.7 and Python 3.4 and up.
To create your own desktop web app, import and set up the WebApp class.
.. code:: python
from webappify import WebApp
app = WebApp('OpenStreetMap', 'https://www.openstreetmap.org', 'osm.png')
app.run()
This will create a window with the website, using the icon provided.
.. note::
If your site needs Flash Player, you'll need the appropriate Flash Player plugin installed system-wide. For QtWebKit
you will need the NPAPI plugin, and for QtWebEngine you will need the PPAPI plugin.
