By default, Qt will grow the width of a tab button to fit the title text
of the tab. For long titles or file:// URLs, this looks rather bad. This
sets a min/max tab width to prevent such infinite growth.
To do this, we have to subclass both QTabWidget and QTabBar, because the
functions to be called/overridden are protected.
If the left-hand side of the tab is already occupied with an audio state
button, we would add a second button to the right-hand side. Prevent
that by checking if the occupant is our audio state button.
This implementation uses a really basic WebView to update stats once
a second. In the future it might make more sense to both move the
details into LibWebView, and to create a native widget for each platform
to remove the overhead of having an extra WebView.
On macOS, the "close tab" button is on the left, so we should place the
audio state button on the right to avoid conflict. Rather than an OS
ifdef, we do this by detecting if the left side is occupied.
We were errantly always referring to the active tab when the audio play
state changed, and when clicking a tab's audio state button, by way of
BrowserWindow::view().
It turns out we also can't copy / rely on the tab index provided to the
signal in any asynchronous context. If the tabs are rearranged, so are
their indices. Instead, capture a pointer to the tab of interest - this
should be safe as we wouldn't be able to click a tab's audio button if
that tab no longer exists.
With this change, we can click the audio button from any tab in the Qt
chrome, and re-arrange tabs at will. The AppKit and Serenity chromes do
not have this issue.
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 to the left of the favicon 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 ensures we consistently show a favicon and that we update the title
to at least display the page URL when there isn't a <title> tag. We
would otherwise continue displaying the previous page's title.
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.
Some Wayland compositors have support of fractional-scale-v1 protocol.
The protocol allows compositor to announce a preferred fractional scale
on a per-wl_surface basis. Qt forwards these Wayland events to an
application using a usual DevicePixelRatioChange event. However, in
contrast to the other platforms, this DevicePixelRatioChange event is
issued directly on widgets and not screens. Additionally, the exact
fractional scale is stored in QWindow object and not the current screen.
Note that in theory it is possible to obtain per-screen fractional
scaling on Wayland by interpolating data provided by wl_output and
xdg_output events but qtwayland does not do that.
If fractional-scale-v1 is not available, qtwayland will still fire
per-Widget DevicePixelRatioChange events, but, obviously, with the
per-screen possibly larger ceiled scaling.
This whole thing makes handling DPI changes on Wayland really simple.
All we need to do is to intercept DevicePixelRatioChange events firing
on QWindow objects and call the old device_pixel_ratio_changed handler
with the window's devicePixelRatio(). The only caveat here is not forget
to always set QWidget's parent before calling devicePixelRatio() on it.
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).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
When a QObject subclass (widgets, etc.) are provided a parent, then
ownership of that object is passed to the parent. Similarly, objects
added to a QLayout are owned by the layout.
Thus, do not store these objects in an OwnPtr.
There's no need for 2 overloads for String and DeprecatedString, we can
just use a StringView. This also avoids some cases of needlessly
allocating a DeprecatedString from a StringView when calling this
method.
Ladybird on Serenity currently only uses F12, and on other platforms
only uses ctrl+shift+I. Most browsers support both hotkeys, so let's do
the same for consistency.
Note that the AppKit chrome cannot support both shortcuts. macOS does
not allow setting multiple "key equivalent" strings on an action. There
are some questionable hacks we could do to support this eventually, but
for now, just ctrl+shift+I is supported on macOS.
It is currently a bit messy to pass these options along from main() to
where WebContent is actually launched. If a new flag were to be added,
there are a couple dozen files that need to be updated to pass that flag
along. With this change, the flag can just be added to the struct, set
in main(), and handled in launch_web_content_process().
After moving to navigables, we started reusing the code that populates
session history entries with the srcdoc attribute value from iframes
in `Page::load_html()` for loading HTML.
This change addresses a crash in `determine_the_origin` which occurred
because this method expected the URL to be `about:srcdoc` if we also
provided HTML content (previously, it was the URL passed along with the
HTML content into `load_html()`).
These classes are used as-is in all chromes. Move them to LibWebView so
that non-Serenity chromes don't have to awkwardly reach into its headers
and sources.
The issue noted in the removed comment no longer seems to apply. The URL
loaded here is triggered before WebDriver even issues the POST /session
command.
When we launch Ladybird, we currently:
1. Create a BrowserWindow, whose constructor navigates to the configured
new tab page URL.
2. Then navigate to either "about:blank" or whatever URL is provided via
the command line.
This patch removes step 2 and forwards the URL from the command line (if
any) to BrowserWindow. BrowserWindow's constructor then either navigates
to that URL or the new tab page URL.
Currently, if the JS console is open and tied to the last opened tab in
the browser window, it will prevent the main process from exiting when
the last tab is closed. This change explicitly closes that tab before
closing the window (if it's the last tab), allowing Qt to delete the
Tab object.
