This will create a window with the website, using the icon provided.
Additional Options
------------------
Version 0.2 comes with the option of minimizing to the system tray. Simply pass ``canMinimizeToTray=True`` to the class
and a tray icon will be installed with the necessary menu options.
.. code:: python
app = WebApp('OpenStreetMap', 'https://www.openstreetmap.org', 'osm.png', canMinimizeToTray=True)
Clicking on the tray icon will show the window, while right-clicking will show the menu.
.. 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.
