Mozzarella Ashbadger — Upgrade your browsing with tabs
Mozarella Ashbadger is the latest revolution in web browsing! Go back and forward! Print! Save files! Get help! (you’ll need it). Any similarity to other browsers is entirely coincidental.
If you think this example app is neat and want to learn more about PyQt in general, take a look at my ebook & online course "Create Simple GUI Applications" which covers everything you need to know to start building your own applications with PyQt.
Adding tab support complicates the internals of the browser a bit, since we now need to keep track of the currently active browser view, both to update UI elements (URL bar, HTTPs icon) to changing state in the currently active window, and to ensure the UI events are dispatched to the correct web view.
This is achieved by using intermediate slots which filter events, and by adding signal redirection (using lamba functions to keep it short).
Icons used in the application are by Yusuke Kamiyaman.
