Dropping a icon from the dash to the application grid will set this._placeholder

that this._placeholder is still valid in the callback, use the icon parameter
instead.

In addition to the "overshoot/bumping into monitor edge" behavior we already
have, we also want to switch pages when simply hovering above the prev/next
page indicators.
This page switch shouldn't happen immediately though, it needs to be kicked
off using a timeout instead. The reason for that is that the next/prev page
indicators are large areas, and simply dragging there isn't enough of a
gesture to really interpret as "the user wants to switch pages".
After this page switch has been toggled once, it can be repeated using the
same "repeat" timeout we introduced with the last commit.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2581>
Right now we have a behavior in the appGrid where "bumping" the cursor
against the monitor edge during DND switches the page immediately, and
holding it there (at the monitor edge) switches pages again after a timeout.
With the next commit we'll introduce another way of switching pages during
DND, that is hovering over the next/prev page indicator to switch pages. To
allow those two methods to play well together, refactor the "overshoot" page
switching to make the timeout into a more generic "repeat" timeout. This
means we can now divide page switching can be roughly divided into two
different steps:
- Switch page immediately when bumping cursor against screen edge, also
works when repeatedly "bumping"
- Switch page automatically again after a second when keeping the cursor at
the screen edge without moving
We'll reuse the "repeat" timeout that's introduced here in the next commit,
where we'll introduce page switching by hovering the next/prev indicators.

With MR https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335,
the page navigation in the app grid was redone and prominent, always visible
navigation arrows were added. This larger change in the navigation of the
app grid also involved changes to the drag and drop behavior.
Before those changes (in GNOME 42), switching pages during DND in the app
grid worked like this: By "bumping" the cursor against the monitor/appGrid
edge, an immediate page switch would be triggered. Leaving the cursor in
that edge area would then trigger repeated page switches every second. By
repeating the "bump" gesture (moving cursor back into the grid, then
"bumping" against the edge again), it was possible to switch pages even
faster than every second.
When adding the always visible navigation arrows, we briefly tried out a
different way of page-switching during DND with commit 09b975fa: The "bump
against monitor edge" gesture (or "overshoot" behavior as it's called in the
code) was replaced with a hover timeout on the navigation arrows. The idea
behind that was to allow hovering the navigation arrow during DND to
eventually trigger a page switch, which also makes sense.
The replacement of the "overshoot" behavior made some people unhappy though,
so it was decided to bring back the old "overshoot" behavior with commit
4dcae8dd. Due to time pressure before the release that didn't go very well
and we ended up with a mixup of both approaches that doesn't feel too
polished.
So let's try to fix that by first going back to the working "overshoot"
implementation as it was in 42, then slightly refactoring that
implementation, to finally incorporate the new "page indicator hover"
behavior that https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335
originally intended to use.
This reverts commit 4dcae8ddd2.

If we are getting purpose hint changes while the language switcher is popped
up, this likely means the purpose hint was actually triggered by the key
focus change induced by the language switcher popping up.
In this case, we on one hand would like to preserve the state that applied
before thise focus change, and on the other we very much want to avoid the
keymap change that would forget about the keys being pressed.

The quick settings menu is child of an actor at 0,0 coordinates,
simply transformed to look in place. However the parent actor stays
at 0,0, and gets a width/height that is able to contain the child
menu (even though the transform will push it outside the parent
actor).
This makes the parent actor (not meant to handle pointer/touch
input) to cover parts of the shell. Since this actor is also where
the Clutter grab happens, the menu is not dismissed either.
Make this parent actor have a 0x0 size, so that it can still act
as the parent for the quick settings menu, but does not actually
cover any area. This makes clicks around the top left corner work
again while the quick settings menu is opened.

Some gstreamer plugins require a connection to the display server,
so they block until the server is up and running. That's why we
moved the check into the D-Bus service, so that the blocking would
not lock up the compositor itself.
However the block can still delay the service initialization so
much that auto-shutdown hits immediately when returning from the
constructor. If that happens, the proxy on the shell side is no
longer backed by a remote object when the init callback runs, and
all properties therefore resolve as `null`.
As a result, gnome-shell thinks that screencasts aren't supported
and hides the screencast button.
Fix this by holding the service during the gstreamer checks, so
that the auto-shutdown timeout only starts after the service is
ready.

The IBusInputContext currently seems to be a bit sloppy wrt propagating
the current state to engines after those are changed, this results in
engines possibly ending with purpose/hint/etc that do not actually
correspond to the current state.
Ensure this state is cleared on unfocus of our IBusInputContext, so
that the next time the input method receives an input focus, the new
state makes it all the way to the currently active engine.

would miss the PASSWORD hint set on the StEntry, and let passwords

Besides user interaction, there's two users of IBusManager.setEngine():
- The code that toggles all IBus engines off on entries with PASSWORD
purpose.
- The code that toggles completion support on OSK presence.
These are currently pretty oblivious to each other. Make this
interaction more resilient by making all external IBusManager changes
more cautious about directly changing the engine, and revoke properly
the completion mode if it needs be (e.g. changing to a non-XKB engine).
But another notable change is that ibus-typing-booster is now preferred
always, over PASSWORD purpose hints. This is done to avoid possible
doubled attempts to change the current engine (and ensuing IBusInputContext
confusion).

When propagating keys from the OSK, we usually feed these directly to
the IBusInputContext and let the IM handle the effects of this virtual
key event (which may also include feeding a key event back to us).
But these functions may also return a FALSE value if the key was "let
through" by the IM, which means the ball is in our yard again, and
we are responsible of letting this event get to its destination.
If that happens, just fall through, so the string is committed to
the client as an UTF-8 string, or propagated through keyboard events.

Consider the existing input sources MRU only valid if it contained
more than one element to pick from. Fixes the following situation
with initial-setup sessions:
- Initial setup Session starts, with several input sources already
configured ("us" between them)
- InputSourceManager initializes, only the default "us" keymap is
available
- MRU list is constructed, "us" is picked
- InputSourceManager catches up with session configuration, the
other extra sources are added
- MRU list is reconstructed, "us" is already the most recent
- Session ends up with "us" picked, regardless of its position in
the list, and no MRU existing prior to startup
If we consider the intermediate single-element MRU list invalid,
it is still possible to pick the best default source between all
the configured ones (the one that was put first in the list,
basically), after initialization is complete.
But also, it is unnecessary to have if there is a single source to
pick from. After the sources list has two elements or more, the
MRU list will become effective and preserved during changes to
the available sources.

Pipewire 0.3.52 via commit a1f33a99 introduced a change that affects how
long pipewiresrc holds onto the pw_buffers it dequeued. Before that
change the pw_buffer was held until the end of the videoconvert element
at the beginning of the pipeline. After that change the pw_buffer was
held onto until the filesink at the end of the pipeline. This was
starving MetaScreenCastStreamSrc of pw_buffers to record new frames
into, resulting in the majority of frames being missed, especially in
situations in which the encoder was taking longer.
Pipewire 0.3.57 via commit 1ea1d525 will allow queuing the pw_buffer
early again via the `always-copy` option. This however is only a
workaround until a proper solution is found in either pipewire or
gstreamer that does not depend on copying the buffer contents and
instead queues the pw_buffer again after videoconvert as prior to
a1f33a99.
Since it is not clear yet when a proper solution will arrive, this makes
use of `always-copy` as a workaround for now and should be reverted once
it is no longer needed.

The object the SignalTracker belongs to is stored in a map managed by
the SignalManager which keeps a reference to that object. This map is
never destroyed nor is any entry ever removed. This leads to all objects
that ever had SignalTrackers used on them being kept alive even after
all references outside of the SignalTracker are long gone. This then
also extends to other objects which are leaked indirectly through
reference chains from these objects.
And if some of those objects are GObjects, this will prevent them from
being finalized, leaking further resources. A StWidget for example will
not release its shadow textures.
Fix this by destroying the SignalTracker and removing it from the
SignalManager once the last signal it was tracking has been untracked.

If a device has multiple connections set up, then at most one of
those can be active at a time, which is why they are presented
as radio items.
In contrast, VPN connections are not mutually exclusive, each can
be turned on or off independently. Setting :radio-mode on them
currently means that VPN connections can be activated, but never
disabled.
So instead of abusing the :radio-mode property to give VPN items
the UI we want, use regular items that reflect the desired behavior
and explicitly set up the UI the way we want.

The object the SignalTracker belongs to is stored in a map managed by
the SignalManager which keeps a reference to that object. This map is
never destroyed nor is any entry ever removed. This leads to all objects
that ever had SignalTrackers used on them being kept alive even after
all references outside of the SignalTracker are long gone. This then
also extends to other objects which are leaked indirectly through
reference chains from these objects.
And if some of those objects are GObjects, this will prevent them from
being finalized, leaking further resources. A StWidget for example will
not release its shadow textures.
Fix this by using a WeakMap in SignalManager.

We got a shiny new screenshot UI last cycle, but only relatively
obscure ways of launching it: Keyboard shortcut or overview search.
The new quick settings provides us with a natural place to expose
the functionality more prominently, and at the same time reduce
the emptiness of the top row, in particular on systems without a
battery and when locked.

We will expose the screenshot UI from quick settings, including
on the lock screen. It would be odd to restrict keyboard shortcuts
more than the more accessible UI, so relax the modes for the
screenshot-ui and screen-screenshot shortcuts.
We still disable all screenshot shortcuts on the login screen, as
users don't have an obvious way to retrieve the screenshot files.

We currently don't take the session mode's `hasWindows` property
into account when deciding whether window screenshots should be
allowed. Right now that doesn't matter in practice, because all
the ways to bring up the screenshot UI are blocked in those modes
anyway. This is about to change though, so take the property into
account to prevent an information leak.

It is currently not possible to bring up the screenshot UI while
locked, but that is about to change.
We still don't want screencasts in that case, because they are
much easier to abuse for filling up someone else's disk.
That restriction is enforced by inhibiting remote access in the
backend, so trying to create a screencast session will fail anyway.
Still, not offering an action that is unavailable is better than
having it fail silently, so do exactly that.

When we aren't showing the power toggle (read: on systems without

The quick settings code was first developed in an extension, which

Since we put the actual slider into a bin to get a proper focus

NetworkManager can check if a network interface has "internet access" by
invoking a HTTP request.
The URI used for connectivity checking in NetworkManager can be configured
manually in NetworkManager.conf:
[connectivity]
uri=http://portal-check.exmaple.com/nm-check.txt
Portal Helper provides an argument to pass the URI that should be opened.
If this argument is empty it uses http://nmcheck.gnome.org as a fallback.
Pass the URI configured in NetworkManager to Portal Helper instead of
an empty string.

This prevents _sync() being called after actor destruction (since actor

It is generally not possible to differentiate between systems
without bluetooth support, and systems where a bluetooth adapter
is powered down.
We work around that by tracking whether there are any set up devices,
and keep the bluetooth visible in that case, even when no adapter
is present.
However commit eeabdd150c moved updating the setting into the code
that handles adapter changes, which is exactly the place where we
carefully avoid changing the setting because it would be too
unreliable (devices may have already disappeared, or not yet
appeared).
Fix this by changing _setHadSetupDevices() to _syncHadSetupDevices()
and call that everywhere _sync() used to be called, *except* on
adapter changes.

Like OSK key buttons, we must avoid the default grabbing behavior

This mode changes the current IBus engine to ibus-typing-booster
under the rug (i.e. no changes in keyboard status menu) for any
XKB engine selected.
In order to make it useful for the currently selected language,
the typing-booster dictionary is changed to the current XKB
layout language. And since the OSK has its own emoji panel,
typing-boosters own emoji completion is disabled.
These changes only apply as long as the OSK panel is shown,
reverting to the original engine and typing-booster configuration
after it is hidden. This in theory also caters for users that
do have ibus-typing-booster enabled as an input source.
The final effect is text prediction for the language that is
being typed, according to the OSK layout, given that
ibus-typing-booster and the relevant hunspell dictionaries are
used.

This action will replace CLUTTER_KEY_Backspace emission for
the OSK backspace key. Following the available mockups, implement
different modes of operation:
- Single tap deletes a single character
- Long tap starts deleting characters one by one
- Longer tap switches to word-by-word deletion
This is made possible via the input method surrounding text,
inspecting the string to look the previous char/word position
backwards, and relies on IM focus providing enough context.
Since deleting text and getting surrounding text are both
async operations, we make one happen after the other, until
the button is released.

Keep it consistent with the rest of the actions. For long press
handling (i.e. shift turning to caps lock), this also means the
release action should be cancelled after any long press, to prevent
both from taking effect at the same time.
Prior to this commit, we used to switch level (and hide the button
being pressed) on button press, which made its long press handler
never get a paired release and end up triggering caps lock.
Performing the action on release ensures the shift key button does
not fall into this situation, making this issue moot.

Have these defined in the JSON files themselves, instead of trying
to add them from JS while minding the differences in number of levels
and rows.
This means more redundant data in the JSON files, but simplifies
OSK layout creation significantly, and allows finer control over the
appearance without quirks.
As a result, importing data from CLDR is no longer as straightforward
as running an script. After initial import, manual editions will be
required to add missing keys, assign key widths, and so on.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2278>
These actions are defined in the JSON files themselves, allowing

When moving to quick settings, we will no longer have a single
parent we can hide instead.
This is only really needed for VPN - devices go away when networking
is disabled, connections (as in: configuration) do not - but it's

_shouldBeVisible() method the VPN section can override.

If any device is in hotspot mode, use the corresponding item as
primary. Disable the (future QuickMenuToggle) menu in that case,
and turn off the hotspot when activated rather than toggling the
global wireless switch.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
Wireless items represent a single adapter, but wireless connectivity
is controlled globally under NetworkManager.
So instead of delegating activation to items, bind the :checked
property to the global :wireless-enabled property and toggle it
on activate.
As any wireless devices will change their state to UNAVAILABLE
when wireless is disabled, don't remove corresponding items in
that case to keep the section visible.
We don't want to hide the button to turn Wi-Fi back on when toggled
off :-)
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
Whether the device is used as a hotspot is currently only
used internally for the name and icon-name properties.
But hotspots need special treatment in the toggle as well,
so turn the method into a GObject property.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
As the sections are about to turn into quick toggles, they need
to be able to perform an action on click.
Add an activate() method for that purpose, which either disconnects
all active items, or connects the primary item.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
DeviceItems are sections, and therefore not actually activatable.
However when we port to quick settings, those toggles will need
to do *something*.
For that reason, provide an activate() implementation that
1. deactivates the device if currently connected
2. delegates the action to the most-recently used item,
the first visible item or the auto-connect item (in that
order)
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
The primary indicator is a bit tricker than the VPN one: The source
of the binding can change depending on the connection, and we still
want to show it when there is a network connection we don't know
about (either because we don't handle the device type, or the
device isn't managed by NetworkManager).
Bindings still make the whole thing a lot nicer though.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
This is the last property that will be needed by the future
betwork quick toggles.
It maps to the same item as :icon-name, except when more than one
item is active. In that case, we overrule the binding and return
a generic name and count (like "VPN (2)").
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
Again no big surprise, a property that will soon correspond to the
quick toggle's icon.
It is more involved than the :checked property though, which is just
a simple boolean.
To keep it as simple as possible, we set up a binding group and use
that to bind the :icon-name property.
As state changes, we then update the group's source with the item
we deem to best represent the section as a whole at the given
moment.
That is (in that order):
- the first active item
- the most recently used item
- the top-most visible item
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
Instead of subclassing PopupMenuSection, it is now a plain GObject
that has a `menu` JS property.
That brings it a tad bit closer to QuickMenuToggle, which is another
GObject with a `menu` property.
We are on the final stretch now. Over the next couple of commits,
we'll add some (fake) properties so we can hook everything up,
and then it's finally time for the big switch.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2408>
We treat wake up requests the same as user activity, as in general
the two behave the same: Turn on the screen and reset the idle watch
until the system becomes idle again.
The big exception is when the screen isn't locked yet. In that case
user activity should interrupt the automatic screen lock, but a
request to wake-up the screen (like showing a notification) should
not.
Address this by ignoring wake-up requests while the screen shield
isn't active, as we can expect the screen to still be turned on at
that point.

This is a region where, if hovered while dragging, immediately goes
to the previous or next page. This behavior was lost during the

This brings back the ability to drop an icon beyong the last page.
Because the acceptDrop() method does not have access to the target
drop actor, to avoid an extra pick or manually calculating it from
allocations, simply store it during DragMonitor.dragDrop(), and
use the target actor in acceptDrop().
This commit also removes the last usage of SidePages, so drop the
enum too.

This simplified the _handleDragOvershoot() callback quite a lot.

Make the next and previous page arrows be StButtons, with their

This was lost 2 commits ago, but now we reimplement this in a

This is a major departure to how page previews used to work. Add
a new layout manager that handles showing and hiding page previews
and navigation arrows. Move most of the code handling page previews
to this new layout manager.
The layout manager allocates at most 20% of the screen width for
the previews, and at least the width of the arrow.
The next and previous page peeking effect is temporarily lost with
this commit, but will be reintroduced in later commits.

AppDisplay will require an extra padding applied on top of CSS
page padding. This is specific to AppDisplay and FolderView.
Add a new AppGrid class which subclasses IconGrid and adds this
extra padding - here called 'indicators-padding'.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335>
The API surface of IconGrid was originally meant to be only
setGridModes(), however findBestModeForSize() ended up being
called by AppDisplay code. Now that FolderGrid sets the modes
correctly, we don't need to skip calling findBestModeForSize()
anymore.
Always call findBestModeForSize() during IconGrid's allocation.
Add an underscore to findBestModeForSize() since it's now back
to be a private method of IconGrid.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335>
Back in the day, adaptToSize() contained mad maths to figure out
icon sizes. Over time, its scope was reduced, to the point where
we are today where it mostly just redoes some quick maths to
predict the grid size based on the CSS box model.
Remove adaptToSize() from BaseAppView and child classes. It still
is an internal detail of the IconGrid class, but it's not exposed
as a "public" method anymore.
This removal is not perfect, as it doesn't move or compensate for
any of page indicators and arrows code. This will be done in follow
up commits introducing a new layout manager for that.

We'll have to dismantle parts of AppDisplay and BaseAppView in

Space will be less of a concern when each sections becomes its own

Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2407>
Devices do not have an associated timestamp, but as we can now
track the MRU order of their connections, it makes sense to consider
the time of the most recent succesful connection the timestamp
of the device item.

We always display items sorted by name, but there are cases where a

Connections have a timestamp property, which records the last time
it was succesfully activated. This is useful information to us, as
more recently used connections are likely more relevant than ones
that haven't been used for a long time (or not at all).
To make use of it in the future, expose that timestamp as a property.
Only connections support it, but we will soon provide a reasonable
value for devices as well, so add the property to the base class.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2407>
Eventually each section will turn into its own menu, which should
include a single settings item.
This also removes the odd duplication of items, now that we avoid
using submenus where possible.
In general this is straight-forward, except for modems: Some
models are now supported by a dedicated wwan panel, while others
still use the generic network one.
Address this by adding items for either panel, but only show one
at a time. The new panel is used if *any* modem is supported,
only when all modems require it, the legacy panel is used.
Hopefully that shouldn't be an issue for many users, as using many
different modems with different capabilities should be fairly rare
(except for Aleksander Morgado, but I think he can handle it)
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2407>
We currently stopped using submenus altogether, but that only works
- if there is a single connection that represents
the device as a whole
- if there is just one device, so it is unambiguous
what device items belong to
To implement that behavior, add a 'single-device-mode' property that
NMDeviceSection can set on its items, and have items update their
'use-submenu' property based on that.
For wireless devices it's a straight mapping, as its items represent
wireless networks that can appear and disappear by just walking around
(multiple wifi adapters also sounds rather fringey).
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2407>
Now that device sections manage a list of items, and the VPN section
manages a list of items, it's time to split out a shared base.
The class will get more involved over time, and eventually become
the base of all network quick items.

We got the indicator out of the business of tracking connections,
now it's time to do the same for devices.
Let sections track device additions and removals, and create device
items for them as it sees fit.
It also allows the sections to handle the ::activation-failed signal
by themselves, instead of passing it on from device items.
With this, the indicator is now solely responsible for global state:
Manage the top bar indicators, notify on connection failures, and run
the portal helper when NetworkManager detects a captive portal.
