This adds a motion preference to the browser UI similar to the existing
ones for color scheme and contrast.
Both AppKit UI and Qt UI has this new preference.
The auto value is currently the same as NoPreference, follow-ups can
address wiring that up to the actual preference for the OS.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
This was no longer doing anything. We'll eventually want a way to pass
system default fonts to each WebContent process, but we don't need to
squeeze everything through this API that was really meant for Serenity's
very idiosyncratic font system.
This is to avoid including any LibProtocol header in Objective-C source
files, which will cause a conflict between the Protocol namespace and a
@Protocol interface.
See Ladybird/AppKit/Application/ApplicationBridge.cpp for why this
conflict unfortunately cannot be worked around.
The previous name was extremely misleading, because the call is used for
pushing or replacing new session history entry on chrome side instead of
only changing URL.
Currently the `<select>` dropdown IPC uses the option value attr to
find which option is selected. This won't work when options don't
have values or when multiple options have the same value. Also the
`SelectItem` contained so weird recursive structures that are
impossible to create with HTML. So I refactored `SelectItem` as a
variant, and gave the options a unique id. The id is send back to
`HTMLSelectElement` so it can find out exactly which option element
is selected.
We already display a speaker icon on tabs which are playing audio. This
allows the user to click that icon to mute the tab, at which point the
icon is replaced with a muted speaker icon.
We would previously hide the icon when audio stopped playing. We now do
this only if the tab isn't muted. If it is muted, the muted speaker icon
remains on the tab so that the page isn't stuck in a muted state.
When audio begins playing, add a button as an accessory view with a
speaker icon to indicate which tab is playing audio. This button is
currently disabled, but in the future may be used to mute the tab.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
The AppKit chrome currently handles all input events before selectively
forwarding those events to WebContent. This means that WebContent does
not see events like cmd+c.
Here, we make use of LibWebView's input handling and wait for LibWebView
to inform the chrome that it should handle the event itself.
The IPC layer between chromes and LibWeb now understands that multiple
top level traversables can live in each WebContent process.
This largely mechanical change adds a billion page_id/page_index
arguments to make sure that pages that end up opening new WebViews
through mechanisms like window.open() still work properly with those
extra windows.
Instead of spawning these processes from the WebContent process, we now
create them in the Browser chrome.
Part 1/N of "all processes are owned by the chrome".
These IPCs are different than other IPCs in that we can't just set up a
callback function to be invoked when WebContent sends us the screenshot
data. There are multiple places that would set that callback, and they
would step on each other's toes.
Instead, the screenshot APIs on ViewImplementation now return a Promise
which callers can interact with to receive the screenshot (or an error).
With this change, chrome no longer has to ask the WebContent process
to paint the next frame into a specified bitmap. Instead, it allocates
bitmaps and sends them to WebContent, which then lets chrome know when
the painting is done.
This work is a preparation to move the execution of painting commands
into a separate thread. Now, it is much easier to start working on the
next frame while the current one is still rendering. This is because
WebContent does not have to inform chrome that the current frame is
ready before it can request the next frame.
Additionally, as a side bonus, we can now eliminate the
did_invalidate_content_rect and did_change_selection IPC calls. These
were used solely for the purpose of informing chrome that it needed to
request a repaint.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
