The port away from the old Shell.GenericContainer actor turned many JS
classes with a corresponding actor property into Clutter.Actor subclasses.
For compatibility reasons, those properties were kept around for a while.
They were now removed and any code that still uses them should be adjusted.
Facilitate that transition by defining the compatibility property on
Clutter.Actor itself, but log a warning every time it is accessed.

We currently copy the app icon menu behavior, which puts a separator

Work around a known regression from [1] that caused the volume bar in
the OSD window to never be hidden, even if the volume is set to 0. This
happened because the border radius of the barLevel is always drawn
without ensuring that the actual bar is visible.
So simply check if the value to draw is 0, and if it is, don't draw the
border radius of the bar at all. This will still result in incorrect
representation of values that have a width smaller than 2*border-radius,
but at least the bar looks right for a width of 0 now.

When determining the biggest icon size that fits the available height,
we first subtract the additional space requirements of icons (spacing,
padding, running indicator etc.) and then divide the result by the
number of icons to get the maximum size available to each icon texture.
In the above, the additional space requirement of each icon is taken
from the first icon (as all icons are assumed to be the same), and
calculated as the difference between the icon button's preferred height
and the currently used icon size.
To make sure that the icon is actually using the dash's current icon
size (even while animating to a new icon size), we enforce its height
during the size request and restore its original height afterwards.
However after some recent changes, that step is causing troubles:
For some reason, the original height may be 0, and when we restore it,
we end up forcing a fixed non-height that bypasses the regular size
request machinery.
While it is unclear where exactly the zero height comes from (maybe
waiting for a valid resource scale?), it is clear that it's best
to avoid forcing a fixed height. So instead of making the icon
texture comply with the assumed icon size, adjust the calculations
to use its current height request.

We recently added offsets to world clocks that represent the location's
timezone as UTC offset. However for most users, that representation is
overly technical and less helpful than the difference to their local time.

We currently use the city name for all location except named timezones.
However locations only have a city name if they are of level CITY or
DETACHED, or if they are of level WEATHER_STATION with a parent of level
CITY.
So when libgweather commit d7682676ac9 moved weather station locations from
cities to countries, it broke their names in the world clocks section.
To fix this, stop making assumptions about when we can use the city name
and simply try it first for all locations and fall back to the plain name
if its not available.

Currently all the widgets using BoxPointer and so popup actors are always drawn
at screen origin and then shifted at paint time in the proper position.
This doesn't work when using resource scale, since the widgets need to know
in which monitor they currently are in order to use properly scaled resources.
So, basically revert commit 22c22e0d7 and go back using the actual actor
coordinates for positioning and the actor translation for animating it, as the
relayouting issues of the past seem to be gone now.

Inserting a workspace is implemented by appending a new workspace, then
shifting all windows after the "new" workspace up. This has an unintended
side effect on sticky windows, as changing its workspace will unstick it.

anyway, given that they should be on all workspaces (including the original
workspace and the target one).

The monitor index is not something that gnome-shell and
gnome-settings-daemon seem to be agreeing about. Using the connector
string is a much more reliable method of identifying a specific screen
and we are indeed using this already for monitor labling.

user tries to use the old API, then the OSD will simply show up on all
monitors (which is the status quo currently anyway).

Now that the existing touch/touchpad gestures in windowManager only
handle normal mode, add corresponding gestures for the overview and
hook them up to the existing workspace scroll animations.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/516
The window group is hidden while in overview, so the stick-to-content
animation isn't visible either. Worse, the gestures messes up the
position of window actors in that case. Just limit the gesture to
normal mode for now, we will soon add it back in the overview with
its own animation handling.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/516
The touch/touchpad gestures to switch workspace currently hard-code
the modes in which we want the gestures to work. While these modes
are correct, the existing switch animation only works in NORMAL mode,
not in the overview where the window group is hidden. The easiest way
to address this is to handle both cases completely separately, namely
use separate actions in- and outside the overview.
Make the existing usable in that way by making the list of allowed
modes a constructor parameter.

ClutterContent's get_preferred_size should return a boolean weather the

This call just went through stomping over previous drag operations if any,
_maybeStartDrag() accounted for this, but other callers (well, WindowClone

This broke shell state by preserving connected captured-event handlers if
one tried to drag multiple windows simultaneously through multitouch. We

The bind constraint that replaced the Shell.GenericContainer in commit
f4682748fa is subtly different from the previous code:
It forces the actor to have the same size as the stage, rather than just
requesting that size.
This breaks the magnifier which relies on the UI being able to be bigger
than the display size. Fix by going back to using a custom actor.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/646
The texture cache now returns an actor with an appropriate ClutterContent

Fix this by making sure the image is already loaded with the desired
dimensions.

If the user's real name is too long to fit the menu comfortably, we are
supposed to use the username instead. However since commit f8e5e3e435,
we no longer set a max-width on the menu as a whole, but instead base

the system menu ended up there, so the name is now allowed to grow
indefinitely.

The menu grabs the key focus when opened, which takes focus away from
whichever actor triggered the keyboard. And as the menu doesn't have
any text entries, the keyboard is popped down as a result.
Prevent this by making the menu items unfocusable, so the keyboard
focus just stays where it is. Considering that the menu is part
of the on-screen keyboard itself, not being keyboard-navigatable
isn't a big deal here.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/171
Menu items use a single 'active' state that follows both hover and
keyboard focus. It therefore makes sense for the active item to always
grab the focus, in particular as an item that is sensitive but not
focusable by keynav would be rather weird.
As it turns out, we do have a case that is weird enough where we want
exactly that, so only grab focus if the actor's :can-focus property
allows it.

Window titles aren't restricted in length, so the menu may end up unwieldily

With the app menu being phased out entirely, there's no good reason to

The GtkSettings was originally introduced to inform applications about

Certain keybindings should continue to work even when a popup
menu is on screen. For instance, the keybinding for showing
the app menu and the keyinding for showing the calendar are
examples.
This is achieved by putting in place a special "POPUP" action
mode, whenever a popup menu is active. This mode replaces
the (e.g., "NORMAL" or "OVERVIEW") action mode that was in place
for as long as the popup menu is active.
But those keybindings should not work when the user is at the
unlock dialog (which uses an action mode of "UNLOCK").
Unfortunately, since commit c79d24b6 they do.
This commit addresses the problem by forcing the action mode
to NONE at the unlock screen when popups are visible.

This keyboard works similar to GTK+'s emoji chooser (actually, both pull
from the same JSON file). Emojis are categorized in sections and variants
and kept in a "model".
The EmojiPager actor then uses this model to generate pages on-the-fly as
the user swipes around. This is an important optimization since the amount
of actors would rival with the rest of the shell otherwise.
The EmojiSelection object puts the EmojiPager, the page indicators and
a KeyContainer with the bottom row of emoji section shortcuts together to
implement the emoji panel as a whole.
The Keyboard object hooked this to an "emoji" key, which is just visible
on the Clutter.InputContentPurpose where showing an emoji would be
meaningful. Otherwise the surrounding buttons are made a bit wider to
cover up for it (i.e. as it was before).
In order to cater for emoji panel usage, we want something like PageIndicators
except:
- It should have horizontal disposition
- It should not be animatable (?)
- It should not be reactive
Separated PageIndicators into a base, non-animated widget, and an
AnimatedPageIndicators that can be used on appDisplay.js. Reactiveness is
set through an extra method, and layout is set as a construct argument.
This will be useful as we want other panels (eg. emoji) to preserve aspect
ratio with the rest of the OSK. Separate the aspect ratio management logic
into this container that will be the parent of them all.
Since commit 447bf55e45 we turn the top bar translucent when

back to the fully opaque top bar.

This is actually papering over bugs in toolkits. On X11 the Xserver will

Besides the device grab on the drag device, also set up a captured-event
handler to catch other devices (except the keyboard) while the DnD
operation is ongoing. This makes DnD operations exclusive to others.
Also, disallow it in less aggressive ways if maybeStartDrag() gets called
while there is a current draggable.
This might definitely be nicer (eg. having other grabbed devices emit
leave/end events), but can't be done without major surgery to Clutter.
In the case where the draggable has an actor of its own, state could be
left broken when dragging on a place that would not accept the DnD op.
After button release, drag state is set to "cancelled" and the animation
begins. After the animation is finished, the drag actor would be destroyed
before disconnecting from its destroy handler.
Within the destroy handler, the grab would be undone but drag state would
be left on "cancelled" state for subsequent operations. This results in
DnD oddities and stuck grabs.
In order to fix this, double check in the actor destroy handler that we
are actually dragging before setting the "cancelled" state.

Whenever the AllView needs (re)populating, we used to do one general
g_app_info_get_all() to get all GAppInfo, plus one per app folder in order
to check the ones that fall within that category. This calls results in a
fair amount of I/O blocking the main loop.
In order to ease this, keep the GAppInfo list around in AllView, and make
the AppFolders use it when figuring out the contained apps. Since reloading
the AllView results in AppFolders regenerated from scratch, the app info
list is ensured to be up-to-date for any later change within the AppFolder
(eg. through the GSettings key changing).
As the list was already filtered in the first place, we can also remove
the try{}catch() in AppFolder in order to discard desktop files with
invalid encoding.

Rather than explicitly destroying the session after calling close(),
destroy it from the `closed` signal handler.
This also means we can make the method internal.

In case there are any internal ways the dialogue can close itself
without calling its own close() method, it’s probably better to do all
our cleanup on a handler for the `closed` signal instead.
This should introduce no functional changes except ensuring the
polkitAgent cleanup is always done.

Otherwise the session could outlive the dialogue, emit a subsequent
signal, and its callback would reference finalised objects/widgets from
the dialogue. The PolkitSession object is implemented by
libpolkit-gobject, so we have no guarantees about its reference counting
— the session object could keep itself alive in another thread, or be a
singleton. In all likelihood, the session hangs around for longer than
the dialogue due to differences in when the two objects are garbage
collected.
This can be triggered by running `pkexec true` from a gnome-terminal
window, then calling `pkill pkexec` from another terminal (on a
different VT or via SSH). This causes the dialogue to be cancelled by
polkitd.

The built-in calendar isn't meant to replace a full-fledged calendar
app, which is why clearing event messages only hides the event in
gnome-shell rather than deleting the actual event. This has turned out
to not be overly useful and often confusing - it creates a discrepancy
with visible events in apps, isn't revertible in a non-obscure fashion
and non-obviously limited to the current date.
As we are considering moving events out of the message list and back to
the calendar, it looks like a good time to remove that ability and keep
notifications as the only removable messages.

We currently deliberately avoid chaining up in derived policy
constructors to not override properties with their defaults.
That's a neat trick that will stop working when porting to ES6
classes, as chaining up is necessary to actually initialize the
object there (including "this").
Address this by turning all properties into (overridable) getters
that are backed by private properties by default.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/350
The _createPolicy() method of a subclass usually depends on some
constructor parameters that need to be set before chaining up to
the parent. This works fine with Lang.Class, but will break with
ES6 classes, as "this" is only initialized after chaining up.
Prepare for this by not creating the policy in the constructor,
but when it is first accessed.

Check via Polkit if the current user is actually allowed to enroll
devices before trying to do so. If not, show a notification that
explains that a system administrator needs to authorize the device.
Clicking on the notification will guide the user to the thunderbolt
control center panel. Before this patch, when the current user was
not allowed to enroll a device a polkit dialog would pop up which
is confusing because it did not contain any information why it was
shown. This patch implements the behavior as designed (see [1],
section "Multi-user environments").

Since commit 5fb8d4f730, a NotificationMessage's notification property

the same time as the notification.

The picked target actor may be destroyed (e.g. hover style change
resulting in the ClutterTexture to be destroyed). If we don't handle
this, GJS will abort when it sees the exception caused by Javascript
code trying to access the destroyed target actor.
To handle it, listen on the 'destroy' signal on the target actor, and
repick, so a valid actor is passed to the next motion callback.

When a fullscreen application is focused,
toggling the overview via hot-corner is disabled,
even when the overview is currently visible.
This only makes sense, when the overview is
hidden to not to disturb the behaviour of the

it should work there like when a non-fullscreen-
application is focused.
So, always allow hiding the overview using the
hot corner when the overview is visible.

The intention of commit 4dc20398 was to disable unredirection while
banners are shown, but the ::done-displaying signal currently used for

Fix this by tying disabling unredirection explicitly to the lifetime
of the banner actor.

The only reason for `vfunc_paint` and `vfunc_pick` existing was to
implement a culling optimization. Although that optimization actually
made performance worse than none at all because it forced the painting
and picking cycles to spend more time calling into JavaScript.
Turns out we don't have to choose between native code and culling though.
Just reimplement the culling using native ClutterActor functions and we
get the benefits of both.

Back in the day, there was a proposed system of tracking apps in a
specific context.
The inspiration was that you may have used apps in multiple modes:
Firefox may have been used in both "Programmer Reference" and
"Kitten Videos" contexts. Early user response to the feedback wasn't
too positive - context switching is something that humans have trouble
doing implicitly, let alone explicitly. The old codebase still has a
few remnants of this around; let's finally put them to rest.
Note that we still write out a dummy context tag to the XML file - old
versions of the shell will flat out crash if you don't have one of those
in there, so just leave it in for compatibility sake.

The pending-charge state means AC power is on but the battery is not
being charged. This can happen because its charge is above a certain
threshold, to avoid short charging cycles and prolong the battery's
life, or because the PSU is not powerful enough to charge the batteries.
Instead of lying to the user about something being estimated, we should
simply tell the truth and set the label to "Not Charging".

When we started to only show a single caption at a time, we allowed
title captions to be wider than their corresponding window preview.
But while overlapping neighboring previews is fine, we shouldn't

While this sounds counter-intuitive, the image-path hint value might also
be used with URIs or icon names.
As per freedesktop standard:
The "app_icon" parameter and "image-path" hint should be either an URI
(file:// is the only URI schema supported right now) or a name in a
freedesktop.org-compliant icon theme (not a GTK+ stock ID).
Thus the image-path hint should also be parsed as it happens for the
app_icon.
Reuse same logic, by falling back on _iconForNotificationData with the
hint value.

We have a callback that will call close() when the notification is
destroyed, and a callback that will call destroy() on the notification
when the message is closed.
Currently, if the notification is destroyed we'll execute our callback
that will call again destroy() on the notification. That's bad
practice in general, and it also has the side effect of resetting the
destroy reason.
This commit avoids re-destroying the notification by dropping the
notification reference on destroy.

Differently from the fd.o notifications, Gtk notifications do not
have a mechanism to update themselves. Instead, when a new
notification is received for an ID already known to the notification
daemon, the old notification is dismissed and a replaced with a new
one.
Currently though, there is no way to distinguish a notification that
was dismissed because of an user interaction, or because it was
replaced. That is an useful piece of information, so add a new value
to the NotificationDestroyedReason enum to account for it.

When gnome-shell receives the signal of 'set-content-type' from ibus,
gnome-shell calls KeyboardManager.holdKeyboard() and
KeyboardManager.releaseKeyboard() and the functions change the current
input focus in GNOME Xorg and it could result in closing a popup window
which has a password entry by focusing on the entry.
The solution is to stop to call the APIs on 'set-content-type' signal.

The `reactive` property of icon actors was being restored multiple times
over the course of the pulse animation, all at slightly different times
as each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a pulse animation, limiting its smoothness and performance.
The solution is to not toggle the `reactive` property in the pulse
animation at all, which avoids incurring multiple full stage relayouts.
As a bonus, this means the icon under the cursor pulses with the correct
selection highlight, appearing more seamless and responsive.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/261
The `reactive` property of icon actors was being restored 24 times over
the course of the spring animation, all at slightly different times as
each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a spring animation hogging the CPU and limiting the frame rate.
The solution is defer and batch the cleanup for all icons until after the
last icon has finished animating. This way the CPU impact of the style
change and stage relayout isn't felt during the animation so the frame
rate remains higher and smoother. The overall CPU usage of the animation
is also reduced as the remaining relayouts are much more likely to be
grouped into a single frame.
Icon spring animation performance on an i7-7700:
Before: 83% CPU and 47 FPS
After : 78% CPU and 54 FPS
which is about a 22% increase in performance per clock (FPS/CPU).

The switcher popup is a large, mostly transparent actor that
should cover all the clickable area of GNOME Shell. In Clutter
terms, it should cover the whole stage.
By binding it to the primary monitor, the Alt+Tab behavior

clicking at empty spaces at other monitors.
Fix that by binding the SwitcherPopup to the whole stage,
and not only the primary monitor.

Since we started to show OSD windows on all monitors, OSD windows are
destroyed when the corresponding monitor is disconnected. We shouldn't
leave any signal handlers around in that case - they prevent the object

When maxLevel is > 100%, first OSD appearance was capping the current
level to 100%. Consecutives key press were then OK.
Ensure we setMaxLevel before setting Level itself, so that correct cap
value is applied.
App folder popups take a grab when opened, and as we don't pass any
particular pushModal() parameters, all keybindings are blocked. While
this makes sense for most keybindings that would interfere with the
popup interaction, others like volume/brightness keys or screenshots
can be allowed safely.

Instead of taking care of the PanelMenu.ButtonBox.container
destruction by itself, delegate that to the very object that
created it in the first place: PanelMenu.ButtonBox itself.
This is the last remaining usage of Shell.GenericContainer
in the codebase, and posed small challenges compared to the
other removals.
A new St.Widget subclass called InputSourceIndicatorContainer
was added as a replacement to the Shell.GenericContainer. It
was needed because GNOME Shell needs to override the regular
size allocation functions, but InputSourceIndicator already
is a St.Widget with its own size allocation overrides.

Because we're late in the cycle, and don't know how many
extensions actually rely on this API, this commit adds
back the BoxPointer.show() and .hide() functions, with
warning messages to notify consumers that this is going
to be removed.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Pretty much like dd4709bb2, BoxPointer's show() and hide()
functions will clash with Clutter.Actor's ones.
In addition to that, on a conceptual level, the current API
is not great, because calling boxPointer.hide() won't result
in boxPointer.actor.visible == false.
For these reasons, rename show() and hide() to open() and
close(). A compatibility layer will be added in a following
commit, warning about the usage of show() and hide().

LayoutManager is currently a pure JavaScript class that
relies on the rudimentary Signals.addSignalMethods() to
handle signals. This is an inefficient implementation of
one of the most central classes in GNOME Shell.
In addition to removing Shell.GenericContainer, then,
turn LayoutManager into a proper GObject.Object subclass.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
In the next commit, we will turn PanelMenu.ButtonBox into a
St.Widget subclass. As a domino effect, PanelMenu.Button will
become one too, and so will Panel.AppMenuButton.
When that happens, the current show() and hide() functions in
Panel.AppMenuButton will clash with Clutter.Actor's ones.
To avoid that, rename these functions to fadeIn() and fadeOut()
and avoid a name clash.

This is another straight port from Shell.GenericContainer.
The important thing to notice is that the calculation is
broken if the StThemeNode helpers (adjust_preferred_* and
adjust_for_*) aren't used.
The downside of this patch is that it removed the skip_paint
from the thumbnails. Keeping it would add an unecessarily
large amount of code.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Removing Shell.GenericContainer from the IconGrid class was
challenging because it needs the "skip paint" API from it.
This API was added, too, as a workaround to the inability
to override vfuncs from GJS.
The overrides are largely copy-pasted and translated versions
of the Shell.GenericContainer code.
The IconGrid:key-focus-in signal was renamed to :child-focused
to avoid clashing with ClutterActor:key-focus-in.
In GridSearchResults, the internal IconGrid had it's y_expand
set to false, so it doesn't push other search elements (the
list results mainly) to the bottom of the screen.
Because skip paint wasn't and still isn't a GObject property,
rename it to _skipPaint to reflect that.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
As part of our quest to obsolete Shell.GenericContainer, IconGrid will
become a Clutter.Actor subclass. As the ::key-focus-in signal would
clash with Clutter.Actor::key-focus-in, rename it to ::child-focused.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
DashItemContainer currently animates the scale and opacity
of its child when zooming in. This is visible when adding
a new favorite item to the dash; the items will zoom in from
the center.
After the previous commit, however, the zoom animation got
slightly broken, and looked like the icon was coming from
the bottom instead of the center.
Fix that by setting the scale and opacity of DashItemContainer
itself, instead of its child. Remove the unused code after that
too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Pretty much like the previous patches, this extends St.Bin. The
most interesting aspect of this patch is that most of the sizing
routines of the icons is now delegated to the actors and layout
managers, removing quite a bunch of code.
The 'spacing' theme property is now redirected to StBoxLayout's
spacing property. Also adjust the Dash code to stop forcing a
potentially invalid width in the first icon too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
This commit removes all the uses of Shell.GenericContainer from
SwitcherPopup.SwitcherList. Compared to the other patches, this
one was specially trickier to get right, and a few invasive
changes needed to be done.
The most noticeable one is that the allocation of the items is
done entirely by St.BoxLayout -- we don't manually allocate them
anymore. To make it work, get_preferred_width() had to calculate
the correct value. It now assumes that:
* Minimum width: the minimum width of the widest child.
* Natural width: the minimum width of the StBoxLayout (use it
instead of the natural width to force the labels to ellipsize
when too long.)
The AppIcon class became a St.Widget subclass as well, to override
get_preferred_width() and be able to keep the squared shape.
Besides that, add a new SwitcherButton class to reimplement squared
icons without having to resort to hacks in the size allocation
machinery. This class has a single vfunc override to ensure that it
is squared when the SwitcherList is.
The arrows indicating multiple windows are now in this._list
actor to the SwitcherPopup itself, since this._list automatically
manages its own children now.
At last, adapt (but preserve) the hack in CyclerPopup.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Instead of overriding vfunc_get_preferred_width|height(), use the
already available Layout.MonitorConstraint to bind SwitcherPopup
to the primary monitor.
This commit turns SwitcherPopup.SwitcherPopup into a St.Widget
subclass, and gets rid of Shell.GenericContainer usage. Subclasses
were adapted to that too.
This class introduced a new challenge: it overrides show(). As per
discussions, we now call this.visible = true inside show().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
In the process of purging all usages of Shell.GenericContainer
of GNOME Shell, one specific problematic situation that might
occur is when classes have functions that would clash with any
ClutterActor or StWidget function name.
One of such example is SwitcherPopup.destroy(). Right now, this
class is a pure JavaScript class that wraps a real actor, but
soon this will change, and it'll become a St.Widget subclass.
Another problem with functions that mimic the toolkit ones is
the predictability of them; after calling destroy(), that widget
is expected to not be available anymore. In SwitcherPopup case,
it is still available for a short while. In this case, that's not
a big problem, but the show() and hide() functions in other clases
are more problematic because the actor's visibility does not
follow that.
This commit is a first step in cleaning that up, and changes the
SwitcherPopup.destroy() to fadeAndDestroy().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
When adding a favorite, we add the ID to the list of favorites, save the
setting and add the new app to the favorites map. However as writing the
settings value already results in reload() to update the favorites map,
the new app is usually already in the map when we add it.
The only exception is when the ID was found in the RENAMED_DESKTOP_IDS map,
in which case we end up adding both the renamed app and the original one.
Fix this by simply relying on reload() to properly update the map, just like
we already do in _removeFavorite().
https://gitlab.gnome.org/GNOME/gnome-shell/issues/471
On X11, reactive chrome must be added to the input region in order
to work as expected. However that region works independently from
any window stacking, with the result that the unresponsive-app dialog
currently blocks all input in the "covered" area, even in windows
stacked above the unresponsive window.
The correct fix would be to track the unobscured parts of the dialog
and set the input region from that, but that's quite cumbersome. So
instead, only track chrome when the corresponding window is focused
(or the dialog itself of course).
https://gitlab.gnome.org/GNOME/gnome-shell/issues/273
As a mount operation's UI may be reused (for example after mistyping
the password), we only close the operation once the mount has finished
(successfully or with error).
We therefore need to track ongoing operations, which we currently do
by monkey-patching the corresponding volume object. However while the
underlying GVolume object indeed remains the same through-out the
operation, the JS wrapper object isn't referenced anywhere and may
thus be garbage collected, resulting in a stuck dialog.
Fix this issue by tracking active operations explicitly, so that all
involved objects are referenced until the end of the operation.
