Previously we were always pushing to history on the on_load_start
callback. Now we only do that if we are NOT navigating through the
history navigation (loading pages by going back/forward). This is what
the SerenityOS browser does:^)
There are no custom changes for Ladybird in the current copies of those
files, so we just need to ensure to keep Ladybird up to date for any
changes made upstream.
This patch brings over the WebContent process over from SerenityOS
to Ladybird, along with a new WebContentView widget that renders
web content in a separate process.
There's a lot of jank and FIXME material here, notably I had to re-add
manually pumped Core::EventLoop instances on both sides, in order to get
the IPC protocol running. This introduces a lot of latency and we should
work towards replacing those loops with improved abstractions.
The WebContent process is built separately here (not part of Lagom) and
we provide our own main.cpp for it. Like everything, this can be better
architected, it's just a starting point. :^)
This will allow us to share code with LibWebView from SerenityOS.
(This would otherwise not work, since its "WebView" namespace collides
with our "WebView" class.)
Also, we should eventually move towards a more sophisticated
multi-process WebView like OOPWV.
This patch takes the browser history code from the Serenity browser and
wires it up to the QT interface. This is tied in with a few extra
toolbar buttons associated with each tab.
This patch removes the browser WebView from the window and places it
inside a Tab object, all wrapped up in a QT tab control. So far you can
create tabs, but can't close them.
