We are currently creating a signal socket and socket notifier before the
Qt event loop itself has been created. Thus, when we receive a signal,
we are not actually notified when we write that signal number to the
signal socket.
This was also the source of the following error message being displayed
on every launch of the browser:
QSocketNotifier: Can only be used with threads started with QThread
We had numerous NiH-based implementations of audio formats and metadata
that we now no longer need because we either don't make use of the code,
or we replaced its implementation by FFmpeg.
The main motivator here was noticing that --disable-sql-database did not
work with AppKit. Rather than re-implementing this there, move ownership
of these classes to WebView::Application, so that each UI does not need
to individually worry about it.
Choosing options from the `<select>` will load and display that style
sheet's source text, with some checks to make sure that the text that
just loaded is the one we currently want.
The UI is a little goofy when scrolling, as it uses `position: sticky`
which we don't implement yet. But that's just more motivation to
implement it! :^)
This forwards all drag-and-drop events from the UI to the WebContent
process. If the page accepts the events, the UI does not handle them.
Otherwise, we will open the dropped files as file:// URLs.
The identifier "Protocol" is claimed by Objective-C and Swift for use
by the language's built-in protocol conformance feature, which is
similar to Rust traits or Java interfaces.
Rename LibProtocol -> LibRequests, and its namespace from Protocol to
Requests to accomodate this.
Currently, if we want to add a new e.g. WebContent command line option,
we have to add it to all of Qt, AppKit, and headless-browser. (Or worse,
we only add it to one of these, and we have feature disparity).
To prevent this, this moves command line flags to WebView::Application.
The flags are assigned to ChromeOptions and WebContentOptions structs.
Each chrome can still add its platform-specific options; for example,
the Qt chrome has a flag to enable Qt networking.
There should be no behavior change here, other than that AppKit will now
support command line flags that were previously only supported by Qt.
The TabBar itself does not stretch the entire width of the TabWidget,
because it leaves space for the width of the new-tab button. So, we
manually tell Qt to paint the TabBar's background into the gap.
Fixes#768.
Makes use of the fact that QTabWidget automatically reserves space
for "corner widgets", and gives us the ability to override their
location with a custom style.
Also, determine the height of the new-tab button using the height of the
tab bar, instead of a hard-coded 32px which was too tall on MacOS.
The default limit (at least on Linux) causes us to run out of file
descriptors at around 15 tabs. Increase this limit to 8k. This is a
rather arbitrary number, but matches the limit set by Chrome.
Skia painter is visibly faster than LibGfx painter and has more complete
CSS transforms support. With this change:
- On Linux, it will try to use Vulkan-backend with fallback to
CPU-backend
- On macOS it will try to use Metal-backend with fallback to
CPU-backend
- headless-browser always runs with CPU-backend in layout mode
If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
This resolves a bug where if you opened a link in a new tab and quickly
went back to the original, the navigation buttons would update for the
new page shortly after.
