When the rename folder menu is opened the text entry is expected to be
focused and selected for a quick editing.
While this is required it doesn't actually happens since PopupMenu by
default gives the key focus to the source actor, that is then free to pass
the key focus to the menu if there's an user interaction.
In this case however, we want the text entry to be focused once we prompt
the menu, so just use the PopupMenu's focusActor property to ensure it will
handle it for us.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1604https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/720
The PopupMenuManager is supposed to grab and focus the menu actors, with
normal menus we always need to grab the actual menu but set the key focus to
the source actor so that it will be able to move the focus to the menu
child, if requested.
However there are menus such as the RenameFolderMenu that requires the
key-focus once prompted, so provide a focusActor property (defaulting to the
sourceActor) that can be set in order to define the actor to give the
keyboard focus to, when the menu is popped-up.

The menu item ornament is used to put dots or checks in menus or otherwise
to define a padding for a label.
However in some cases we want to create a menu item with no left (in ltr)
padding.
In order to do that, define a HIDDEN Ornament mode that completely hides the
ornament actor.
The naming here might be confusing as this should probably be called NONE,
while the default mode is the invisible one, but it's too late to change it
now.

While commit 3094f863 was intended to cancel the ongoing idle hide
timeout before we start a new one, a mistake slipped in there while
rebasing: Obviously we should check if the signal id is NOT 0 here.
This didn't prevent timeouts being started while old ones are still
running and did override `this._idleHideOverlayId`, which caused the old
timeouts to run indefinitely after an overlay actor was destroyed
because we fail early (and don't return TRUE) in `_idleHideOverlay()`.

Indicate whether dropping an app icon was successful or not by using the
newly added `animateLaunchAtPos()` API of AppIcon which starts a zoom
out animation of the icon at the position the drop happened.
To get the position of the drag actor, we have to forward the arguments
passed to `acceptDrop()` and `handleDragOver()` to the internal drag
handlers of the WorkspaceThumbnails. We can use this position directly
without transforming it to stage coordinates because the actor is a
child of `Main.uiGroup` and the animation actor will also be a child of
this container.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/121
Add a `animateLaunchAtPos()` method to the AppIcon class to animate the
launch of an app at a given position. This allows for a visual

Return the results of calls to acceptDrop that we forwarded to the
Workspace object.
This fixes a bug where app icons that were dragged and released above a

`AppIcon.shellWorkspaceLaunch()` can easily be replaced by checking for
`AppIcon.app` and calling `AppIcon.app.open_new_window()` directly.
For compatibility and to prevent breaking extensions implementing the
function, keep supporting the `shellWorkspaceLaunch` API in AppIcon
while logging a deprecation warning. Also keep supporting the API on
drag sources (without deprecating it) to allow extensions to define
custom actions on their drag sources.

If the search entry does not have any text typed in and a button press
happens outside of the search entry, we set key focus to NULL to make
the search entry appear unfocused.
This is quite intrusive and can easily cause unwanted focus changes, so

entry actually is focused.

Instead of returning and waiting until the old timeout is finished,

As arrow functions have an implicit return value, an assignment of
this.foo = bar could have been intended as a this.foo === bar

Calling await in a loop means the asynchronous operations are
run sequentially instead of in-parallel. Usually that's not
what's wanted, so eslint has a rule to warn about this.
However here we use async/await to handle control back to the
mainloop between steps, so running operations sequentially is
actually intended.

The intention of the code is clearly to operate on a copy, but that's

The legacy indent rule currently ignores arrow functions in parameters
to allow callbacks to not align with the other arguments:
this._someFunctionWithFairlyLongishName(arg1, arg2, arg3,
() => {
this._someOtherFunctionWithLongName(arg1);
});
But as ignoring entire nodes means we can end up with arbitrary
indentation, we should drop the exception. While this would make
the above "illegal" under the legacy config, it conforms with the
non-legacy style, so everything should be fine ...
... except that eslint starts to complain about some function args
that should be fine under the legacy config. Maybe it's thrown off
by the function-arg-in-arrow-function-in-function-arg structure, but
rather than figuring it out, let's just move those to the new style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/725
We are currently inconsistent whether to put the operators in front
of the corresponding line or at the end of the preceding one. The
most dominant style for now is to put condition and first branch on
the same line, and then align the second branch:
let foo = condition ? fooValue
: notFooValue;
Unfortunately that's a style that eslint doesn't support, so to account
for it, our legacy configuration currently plainly ignores all indentation
in conditionals.
In order to drop that exception and not let messed up indentation slip
through, change all ternary operators to the non-legacy style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/725
Some more places where the indentation doesn't comply with either
the old or new style. They slipped through because the legacy eslint
configuration accounts for some patterns by plainly ignoring certain
nodes. We'll address that later, first fix up the indentation errors.

When there is a transition, it's likely that we are animating some part

Updating the window list in the Looking Glass is a costly
operation: it destroys a whole lot of actors, and recreates
them. This triggers CSS changes, repaints, and allocations.
It is specially bad when paired with Wayland's big number

and Epiphany's popup window.
Only update the window list in the Looking Glass when it is

Since ES5, it is possible to create objects with no prototype at all:
let foo = Object.create(null);
Those object won't have any builtin properties like hasOwnProperty(),
which is why eslint added a corresponding rule to its default rule set.
While this isn't an issue that affects our code, there's no harm in fol-
lowing the recommendation and call the method through Object.prototype.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/716
We currently use no less than three different ways of indenting
object literals:
let obj1 = {
foo: 42,
bar: 23,
};
let obj2 = { foo: 42,
bar: 23 };
let obj3 = { foo: 42,
bar: 23
};
The first is the one we want to use everywhere eventually, while the
second is the most commonly used "legacy" style.
It is the third one that is most problematic, as it throws off eslint
fairly badly: It violates both the rule to have consistent line breaks
in braces as well as the indentation style of both regular and legacy
configurations.
Fortunately the third style was mostly used for tween parameters, so
is quite rare after the Tweener purge. Get rid of the remaining ones
to cut down on pre-existing eslint errors.

Since disabling an extension will lead to disabling and re-enabling all
following extensions in the list, always disable multiple extensions by
looping through the list in reverse order.
This lowers the execution time of the event handlers quite a bit if many

Thanks to Philippe Troin for identifying the problem and proposing the
initial patch to change the extension order when reloading.

Only push uuids of newly enabled extensions to the `_extensionOrder`
array if enabling them was successful.
Otherwise, since `_callExtensionDisable()` doesn't remove uuids that
weren't successfully enabled from the array, those extensions get added
to the array multiple times when they're disabled and enabled.

It's currently possible to circumvent the `sessionMode.allowExtensions`
property: For already enabled extensions one can call reloadExtension
via DBus, for new extensions it's possible by adding the extension to
the enabled-extensions gsettings key and setting the
disable-extension-version-validation key (which triggers a reload of
`this._enabledExtensions`) and then calling reloadExtension via DBus.
So to enforce `allowExtensions` while still allowing to update
extensions and keeping the extensionSystem synced with various gsettings
keys, replace the checks for `this._enabled` with simple checks for
`Main.sessionMode.allowExtensions` inside `_callExtensionInit()` and
`_callExtensionEnable()`.
The remaining checks for `this._enabled` are only small optimizations to
prevent running code on irrelevant sessionMode updates.

We're using a vfunc override for `get_paint_volume` to exclude children
with an opacity of 0 from the paint volume and thus decrease the size of
the area we need to paint.
Now if the paint volume is requested during the spring animation (the
real icons are hidden using an opacity of 0 and clones are used for the
animation), `get_paint_volume` returns a paint volume with a height of
0. After that, the spring animation finishes and the icon-opacities are
set to 255 in `_resetAnimationActors`, and since we cache paint volumes
and there's no reason for Clutter to assume it got invalid, the icons
end up not being painted.
Fix this by queuing a relayout of the grid when the opacity of a child
is changed from or to 0, which manually invalidates the paint volume.
The reason why this is not an issue with the paginated icon grid
(all-apps view) is probably because StScrollView invalidates the paint
volume a lot more often than regular containers.

Commit 21e14bd46f fixed this for the
brightness slider, but we have the same problem for volume too. When the
volume is muted - for example in Settings or via a media key, we update
the slider to '0' to indicate this visually. But we also actually invoke
the slider's callback to *set* the volume to zero. That means that the
previous level is overwritten so it can't be restored when unmuting.
The fix is the same - when we update the slider internally ourselves,
don't call the signal handler.

Since we now put a short timeout in before the start of the actual pie
timer we don't start the timer as often as we used to. This allows us to
create a new PieTimer object each time a timeout is started and
therefore play a finish animation independently of other (new) timeouts.

If the circle is complete and the pie timeout finished, we don't need
the lines to the center point indicating the ends of the pie anymore.

If the pie timeout has finished successfully there's no need to cancel

Before the move to Clutters implicit animations with 0846238f6 and
bf497ed64, we used Tweener to do a fake-animation of the opacity and
Tweeners `onUpdate` signal to queue a repaint of the PieTimer everytime
Tweener tries to update the animation.
Now, with Clutters implicit animations, there is no `onUpdate` signal
anymore and also `notify::opacity` no longer gets emitted since the
value doesn't actually change. This lead to the PieTimer no longer being
repainted, which broke the animation.
Fix this by implementing the current angle of the pie using a custom
GObject property `angle` and animating this property using the new
`actor.ease_property` method.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1533
When cancelling the animations of the icon grid, right now we simply
destroy all the clones without resetting the opacity and making the
actor reactive again. So if the spring animation to show the grid is
cancelled by pressing a key to start a search, the icon clones would be
destroyed, but the icon-opacity would still be set to 0. Now if the
Escape key is pressed, viewSelector will show the last active page (ie.
the iconGrid) without a custom animation and only fade in the page, and
because the icons still have an opacity of 0, they will be invisible.
Fix this by always restoring the opacity and reactive property of the
original actors if the animation is cancelled instead of only destroying
the clones.

Since we set the proxy value when the slider changes and set the slider
value on proxy property changes, we run into a cycle.
Before commit 3d3dca4aa this was addressed by not notifying on all slider
changes, but only in reaction to direct user action. Given that since the
splitting out of the BarLevel class those events are handled in a subclass,
that approach is at least unconvential and fairly fragile.
Instead, make the brightness indicator ignore any changes to the slider it
initiated itself.

With 8b368d010 we fixed a bug where the onComplete callback was always
called no matter whether the transition was interrupted before or not.
This exposed another bug: viewSelector depends on this behaviour when
fading out pages: After fading out a page, we call `this._animateIn` to
show the new page. Now if the fade-out animation gets interrupted, with
the correct behaviour of onComplete we end up not showing a new page and
the viewSelector remains empty instead. One case where this happens is
when pressing a key to start a search during the overview-animation.
Obviously we also want to show the new page in case the fade-out
animation was interrupted, so use the onStopped callback instead of the
onComplete callback here.

Since the `notify::allocation` signal will obviously get emitted while
the actor is inside an allocation cycle and we might end up doing
changes to its allocation inside `updateSearch` by hiding or showing the
actor (which queues a relayout), we get a warning from Clutter.
Fix this by delaying the call to the parent method until the next
redraw, which should happen a few moments after the current relayout.

Since commit 1a27ff6130 we use the
allocation width of the GridSearchResults actor to calculate the max
number of results that can be shown for this search provider.
On the first run of the search, when no previous (cached) allocation is
available for the actor of GridSearchResults, the allocation width used
in `_getMaxDisplayedResults` will be 0, which in turn will make
`updateSearch` filter out all results returned by the search provider.
Now if this search provider is the only search provider that's enabled,
after calling `updateSearch`, the `SearchResults` class will call
`_updateSearchProgress` to check if any results are visible, assume
nothing was found and therefore hide the scrollView. This in turn causes
the GridSearchResults actor to not get a new allocation, which prevents
our code to fixup the max number of results on `notify::allocation` from
working: The number will continue to be 0 and we'll never show any
results.
To fix this regression, return -1 in `_getMaxDisplayedResults` if the
allocation width is 0 to inform `updateSearch` that we can't calculate
the maximum number yet and interpret a return value of -1 as "show all
results" in `updateSearch`. The same problem would probably also appear
if the allocation width is anything between 0 and the width of the
iconGrid with one icon in it, although this might as well be a valid
width in case a very small screen is used or with very large icons. So
let's only check for a width of 0 and hope the GridSearchResults actor
won't get weird temporary allocations in that range.

When transitioning to or from the overview, windows travel
a certain distance between their real desktop position and
their place in the overview window grid. The less this travel
distance is, the smoother, more polished, and less jarring
the overall transition looks. This is why it makes sense to
try reordering and repositioning windows to minimize their
travel distance. That being said, there are other factors
that impact the quality of the overview layout, such as how
much the windows get scaled and what portion of the overall
available space they take up.
The existing code tries to minimize the travel distance by
sorting the windows in each row by their horizontal position.
There are, however, two problems with this implementation.
First, it compares the coordinates of windows' left edges as
opposed to their centers, which means it yields unexpected
results when a small window is positioned next to the left
edge of a large window. Second, it completely disregards
vertical coordinates, instead assigning windows to the grid
rows using their monotonically increasing window numbers,
effectively vertically sorting them by the order they were
created in.
This commit changes both vertical and horizontal ordering
to work based on the coordinates of the geometric centers
of the windows. That is to say, windows are first assigned
to grid rows based on the vertical coordinates of their
centers, and subsequently sorted inside each row based on
the horizontal coordinates of said centers. In my testing,
this leads to a much more intuitive and visually pleasing
window placement.

Those checks were carried over from the very first DND implementation;

as we moved away from Tweener for all our animations.
The number of cases where an extension is still using Tweener, creates
draggable actors, *AND* requires the checks for proper functioning
should be indistinguishable from zero, so drop the code.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/669
By now, Tweener is used exclusively to animate changes to the
StAdjustment:value property. But not for long, as now that we
implement the same transition API as Clutter.Actor, we can
re-use the existing convenience method for property transitions
for adjustment changes as well.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/669
The tracking was important in an earlier iteration, but as the helper
functions now remove overwritten transitions before setting up the
new ones, we can just as well connect to the ::stopped signal directly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/668
This is rather embarrassing - we currently confuse the transition with
the finished parameter, which means we always run the onComplete handler
no matter whether the transition was interrupted or actually completed.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/668
Commit 0f178c3b3d added a shortcirtuit to avoid running
an animation on an invisible actor. However, it introduced
a bug where the current page is not properly updated. That
leads to the wrong set of icons being animated under some
circumstances.
Update the current page even if we bail out early.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/667
Properties that aren't marked as animatable don't support *implicit*
animations, but they can still be animated with explicit transitions.
Use the newly added convenience method to cut down further on Tweener
usage.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
While we are now using implicit animations for all animatable properties,
there are still some cases where we animate other actor properties (for
example from a custom subclass) or associated objects like effects.
Those can still be animated using Clutter animations, as long as we use
the explicit API rather than implicit animations. Again this API is
cumbersome and tricky enough to warrant a convenience wrapper.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
Clutter animations work on GObject properties on animatables. The
last commit took care of the latter by turning all animated objects
into actor subclasses, now it's time to make all properties used
in Tweens into GObject properties.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
We have a couple of places where we don't tween the actor, but a
custom property on the delegate object. In order to move those
to Clutter animations, we will need an animatable, so turn those
objects into widget subclasses.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
The set_brightness() method is the most convenient way of controlling
the effect's brightness, but Clutter animations only deal with properties,
so start using the (ClutterColor) brightness property instead.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
Currently WindowDimmer exposes a JS property that is used to control the
underlying effect. This works fine with Tweener, but not with Clutter
animations which we want to use ultimately.
As a first step towards that, expose a setDimmed() method instead of
the property and handle the animation internally, so it can be adapted
more easily.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:
- they run entirely in C, while Tweener requires context switches
to JS each frame
- they are more reliable, as Tweener only detects when an animation
is overwritten with another Tween, while Clutter considers any
property change
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
Setting up implicit animations is more verbose than using tweener, in
particular when setting up a callbacks to run on overwrite or completion.
In order to make its use more convenient, monkey-patch ClutterActor
with an ease() method that works similarly to Tweener.addTween().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
Being able to slow down animations is a helpful debugging tool; to not
lose it when starting to use Clutter's implicit animations, monkey-patch
the appropriate methods to support our global slow down factor.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
As we currently use Tweener for all animations, we have a single place
for hooking up the enable-animations and slow-down-factor settings.
However that will no longer hold true when we'll start to use Clutter's
built-in animation facilities, so add a small helper function that
applies the necessary adjustments.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
Notifications use a transition that overshoots the target value, however
we can only really do that for the position and not the opacity where
some values would end up out of the valid range.
We currently address this by proxying the actual opacity property in a
javascript property, and clamp it to the valid range in an onUpdate()
callback.
This won't be an option if we want to use Clutter animations, so instead,
use separate tweens for opacity and position.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
Unlike Tweener, which doesn't know or care about actor state, Clutter
will skip implicit animations on actors that aren't mapped. This makes
sense of course, but it will break the page indicator animation we
do on map: When we get notified about the container being mapped, the
individual indicators (which are the actors being animated) are still
unmapped.
Resolve this by deferring the animation to a LaterFunc.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
For animating the arrows on the screenshield, we currently use a custom
transition function that tweens the opacity from 0 to maxOpacity in the
first half of the animation, and from maxOpacity back to 0 in the second
half.
This doesn't easily translate to Clutter's own animation framework, so
replace the custom transition with two consecutive tweens which do.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
Dash items are currently animated via the custom "childScale" and
"childOpacity" properties. However since commit efb3025d8c, those
properties actually control the scale-x/scale-y and opacity properties
of the actor itself (not the child), so cut out the intermediate
custom properties in favor of the "real" ones.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
When expanding a submenu, we currently use a single tween to animate
both the submenu actor and the source arrow. We do this by tweening
a monkey-patched JS property on the main actor, which we then use
to update the arrow's GObject property on updates. As Clutter cannot
animate random JS properties, this trick will prevent us from using
implicit animations here.
The only reason I can think of for using a single tween is to keep
both animations in perfect lock step, but as expansion and rotation
are visually quite distinct, this shouldn't be required, so just
set up separate animations for each actor.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
Now that redisplaying is a lightweight operation that only
adds and removes what changed, we can not be concerned about
redisplaying on folder changes.
Redisplaying will be necessary when custom order in the app
grid is implemented, in order to update not only which icons
are hidden, but also their position.
Call _redisplay() in AllView when folders change.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
FolderView and AllView currently check if the item is
present in the BaseAppView._items map, in order to avoid
adding the same icon multiple times.
Now that BaseAppView._loadApps() has a different role --
it returns a list with all app icons, and BaseAppView
diffs with the current list of app icons -- checking the
BaseAppView._items map is wrong.
Make sure there are no duplicated items in the temporary
array returned by all _loadApps() implementations. Remove
the now unused BaseAppView.hasItem() method.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
BaseAppView currently removes all icons, and readds them, every
time the list of app icons needs to be redisplayed. In order to
allow animating app icon positions in the future, however, we
cannot destroy the actors of the app icons.
Previous commits paved the way for us to do differential loading,
i.e. add only the icons that were added, and remove only what was
removed.
Make the BaseAppView effectively implement differential loading.
The BaseAppView.removeAll() method is removed, since we do not
remove all icons anymore. BaseAppView._loadApps() now returns an
array with the new apps, instead of putting them directly at the
BaseAppView lists.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
Next commit will introduce differential loading of
app icons, and will reorganize this part of the
codebase.
When doing that, the ideal symmetry of the new code
would be:
* Update BaseAppView._allItems array
* Update BaseAppView._items map
* Update BaseAppView._grid actor
Move the code in _loadGrid() into _redisplay() so that
we can check in-place which new icons need to be added.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
Now that the three views follow the exact same loading routine
(remove all + load apps + load grid), we don't need each view
call loadGrid() directly anymore.
This is an important step in order to animate adding and removing
icons, since now we can diff old and new app icons properly.
Move all calls to BaseAppView.loadGrid() to a single one after
BaseAppView._loadApps(). Also add the underscore prefix, since
this is now considered a protected function.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
FrequentView is another view that is slightly not unified with how
BaseAppView expects subclasses to load app icons. Instead of using
BaseAppView.addItem() and then calling BaseAppview.loadGrid(), it
adds the app icons directly to the icon grid.
Make FrequentView add icons using BaseAppview.addItem(), and load
the icons using BaseAppView.loadGrid().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
Future patches will diff the old and new icons of views, in order to
animate them when necessary (e.g. adding an app icon to a folder, or
from a folder back to the app grid). In order to do that, all views
must be streamlined in how they load app icons.
Currently, FrequentView and AllView are already following the behavior
expected by BaseAppView, but FolderView isn't. Its icons are loaded by
FolderIcon, and FolderView doesn't implement BaseView._loadApps(),
which makes it impossible to diff old and new apps.
Move the app icon loading routine from FolderIcon to FolderView, by
implementing the _loadApps() method.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/663
Since commit 007d30573 we use an actor effect to apply the radial effect and
we pass the effect to the tweener in order to animate it.
However, we always still remove the previously added tween from the actor,
instead that from the actual target.
So, depending the radial effect state, remove the tweens from the proper target
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/653
We currently assume that user icons are square, which is the case when
set by the users settings panel, but not enforced by AccountsService.
Handle that case by moving the pixel size back to the actor and using
an appropriate background-size style property of 'cover' (which means
the smallest dimension of the image is scaled to fit the desired size).
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1144
A generic, introspectable Shader effect is not only more flexible
than a shader actor, it will also make it much easier to turn
Lightbox into an actor subclass and replace Tweener with Clutter's
own animation support.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/651
Due to typecasting being done when converting floats to integers in
gnome-settings-daemon, a volume of 0.9% in g-s-d will end up as 0% in
gnome-shell. This can lead to a mismatch of icons between the volume OSD
(the icon to use is determined by g-s-d itself) and the shells own
volume indicator (the icon to use is determined by the shell using the
volume received from g-s-d).
To fix this, simply get rid of the conversion from float to percentage
in g-s-d and back to floats in the shell and just send a float/double
value on DBus.
https://gitlab.gnome.org/GNOME/gnome-settings-daemon/merge_requests/78https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/385
LevelBar is not really used, all the checks are implemented inside
BarLevel as well and the accessible name is wrong because the osdWindow
doesn't only show the volume, but also the brightness and other things.
The workaround for updating the bars width is also no longer needed now
that we have BarLevel.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/385
There are some cases (for example when tweening value changes), where
the level will be set to the same value it already is at. Avoid those
unnecessary repaints by checking whether the value is already used and
returning if it is.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/385
AppIcon makes itself draggable, and handles the various DnD
routines such as 'drag-begin' and 'drag-end' by making the
Overview emit the appropriate signals.
However, when destroyed, the AppIcon does not try to finish
any drag operations that started. That causes the event
blocker in AllView not to be updated correctly when dragging
icons to outside folders.
Make AppIcon emit 'item-drag-end' when a drag operation
started and it's destroyed.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/643
For GObject properties, we follow the convention of all-lowercase,
dash-separated names. Those translate to underscores in getters/setters,
so exempt them from the newly added "camelcase" rule.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
This was left-over in commit 2743f18af, and probably is the real reason
why the busy spinner wasn't using the shared AnimatedIcon.Spinner class:
The animation there was much slower.
Still, let's keep the code as-is for now, if we really need a different
animation time, we can add an optional constructor parameter to the
Spinner class.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/640
At the moment the only way to open a folder icon is to click on it;
there's no API to open the icon programmatically.
This commits adds an open method and makes the click handler use
it.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/628
When a FolderIcon is opened, it asks the parent view to allocate
space for it, which takes time. Eventually, the space-ready
signal is emitted on the view and the icon can make use of the new
space with its popup. If the icon gets destroyed in the
interim, though, space-ready signal handler still fires.
This commit disconnects the signal handler so it doesn't get called
on a destroyed icon.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/628
It is important that the FolderView of a FolderIcon always
gets destroyed before the AppFolderPopup, since the view
may or may not be in the popup, and the view should
get cleaned up exactly once in either case.
This commit adds a destroy handler on FolderIcon to ensure
things get taken down in the right order, and to make sure
the view isn't leaked if it's not yet part of the popup.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/628
At the moment AppFolderPopup calls popdown on destruction,
which leads to open-state-changed getting emitted after
the actor associated with the popup is destroyed.
This commit handles ungrabbing and closing from an
actor destroy handler to side-step the open-state-changed
signal.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/628
If an icon already exists in an app view with the same id, the
duplicate is not added on a call to addItem. Unfortunately,
since it's not added, the icon actor gets orphaned and leaked.
This commit address the problem by introducing a new hasItem
method and disallowing callers to call addItem with a duplicate
in the first place.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/628
meta_later_add() is modelled after g_idle_add() and friends, and
the handler's boolean return value determines whether it should
be scheduled again or removed. There are some places where we omit
the return value, add them (although the implicit return value of
"undefined" already gives us the intended result).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/637
The startup/busy indication in the app menu was left out of commit
22e21ad7d1 because it doesn't use a hard-coded image, but as the
image in the CSS is actually the same used by the spinner class,
drop the "custom" styling and use the regular spinner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/636
Trying to disable an extension that is enabled by the session mode
currently has no effect, which is clearly confusing. We could update
the various extension UIs to reflect that via sensitivity, but being
unable to configure extensions based on which session the user picked
at login isn't obvious either.
So instead, add a 'disabled-extensions' gsettings key to list extensions
that should not be enabled which takes precedence over 'enabled-extensions'
and can be used to disable session mode extensions.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
Now that extension loading and the extensions map are no longer shared
between the gnome-shell and gnome-shell-extension-prefs processes, we
can move both into the ExtensionManager which makes much more sense
conceptually.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
Whether or not an extension can be enabled/disabled depends on various
factors: Whether the extension is in error state, whether user extensions
are disabled and whether the underlying GSettings keys are writable.
This is complex enough to share the logic, so add it to the extension
properties that are exposed over D-Bus.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
The existing 'ExtensionStatusChanged' signal has a fixed set of parameters,
which means we cannot add additional state without an API break. Deprecate
it in favor of a new 'ExtensionStateChanged' signal which addresses this
issue by taking the full serialized extension as parameter.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
Serializing an extension for sending over D-Bus is currently done by the
appropriate D-Bus method implementations. Split out the code as utility
function and add a corresponding deserialization function, which we will
soon use when consuming the D-Bus extension API from the extension-prefs
tool.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
Extensions are currently enabled or disabled by directly changing the
list in the 'enabled-extensions' GSettings key. As we will soon add
an overriding 'disabled-extensions' key as well, it makes sense to
offer explicit API for enabling/disabling to avoid duplicating the
logic.
For the corresponding D-Bus API, the methods were even mentioned in
the GSettings schema, albeit unimplemented until now.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
While public methods to enable/disable extensions make sense for an
extension manager, the existing ones are only used internally. Make
them private and rename them, so that we can re-use the current
names for more useful public methods.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
The extension system started out as a set of simple functions, but
gained more state later, and even some hacks to emit signals without
having an object to emit them on.
There is no good reason for that weirdness, so rather than imitating an
object, wrap the existing system into a real ExtensionManager object.
https://bugzilla.gnome.org/show_bug.cgi?id=789852
It makes sense to keep extension-related enums in the same module instead
of spreading them between ExtensionSystem and ExtensionUtils.
More importantly, this will make the type available to the extensions-prefs
tool (which runs in a different process and therefore only has access to
a limited set of modules).
https://bugzilla.gnome.org/show_bug.cgi?id=789852
Commit bd18313d12 changed to a new naming scheme for battery icons,
and used to old icon names as fallback-icon-name for compatibility
with older/other icon themes.
However that fallback code isn't working correctly, as GThemedIcon's
default fallbacks will transform a name of `battery-level-90-symbolic`
to a list of names:
- `battery-level-90-symbolic`
- `battery-level-symbolic`
- `battery-symbolic`
The last one frequently exists, so instead of the intended fallback,
we end up with a generic battery icon.
Address this by specifying the icon as GIcon instead of an icon-name,
where we have more control over how the icon is resolved.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1442
Just as we did for the workspace switcher popup, support workspaces
being laid out in a single row in the window picker.
Note that this takes care of the various workspace switch actions in
the overview (scrolling, panning, touch(pad) gestures) as well as the
switch animation, but not of the overview's workspace switcher component.
There are currently no plans to support other layouts there, as the
component is inherently vertical (in fact, it was the whole reason for
switching the layout in the first place).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/575
While mutter supports a variety of different grid layouts (n columns/rows,
growing vertically or horizontally from any of the four corners), we
hardcode a fixed vertical layout of a single column.
Now that mutter exposes the actual layout to us, add support for a more
traditional horizontal layout as well.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/575
In some cases the style-changed signal hasn't been emitted when
_computeLayout() is called, resulting in the use of the default spacing
and item size values for the calculations.
One case where this happens is when starting a search. Right after the
initialization of GridSearchResults, _computeLayout() is called from
_getMaxDisplayedResults() and the style-changed signal hasn't been
emitted yet. The computed layout will be wrong and the maximum
number of results will also be wrong.
To prevent this from happening, make sure the style has been updated
before doing the calculations in _computeLayout().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/110
The calculation of how many results can be shown in GridSearchResults is
broken: The width of the parent container (resultsView.actor) we're
using as the maximum width right now is the width of the scrollView of
SearchResults (which always expands to the whole screen size). This
width will only be correct if the scrollView (ie. the whole screen) is
smaller than the max width of searchResultsContent, which only is the
case for screens smaller than 1000px.
To fix the calculation, use the width of our own actor and don't get it
using clutter_actor_get_width(), but using the last allocation of the
actor. This way we don't get the preferred width if the actor is not
allocated at this point (it's hidden by _ensureProviderDisplay() when
starting a new search).
Then, when the allocation of the actor changes, rebuild the grid search
results by calling updateSearch() with the old arguments to ensure the
number of visible results is correct. The fact that we're only listening
for allocation changes here is the reason why we never want to use the
preferred width of the actor inside _getMaxDisplayedResults(): While
the actor is hidden clutter_actor_get_width() would return the preferred
width, which we'd then use the as the maximum width. But if the actor
had a correct allocation before, no notify::allocation signal will be
emitted when the actor is shown again because the allocation is still
the same, and we'll end up using the preferred width as maximium width
forever.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/110
The functionality the searchResultsBin container provides can easily be
moved into a subclass of St.BoxLayout, no need for an additional StBin.
The "searchResultsBin" css class isn't used in the stylesheets either.

Object.prototype.hasOwnProperty() is more precise than checking for
falsiness, for instance the following is true:
{ foo: undefined }.hasOwnProperty('foo');
However when checking for a handler ID, a more relaxed check is more
appropriate, as particularly 0 is not a valid handler ID.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/626
For some reason, people are still seeing those after commit d5ebd8c8.
While this is something we really should figure out, we can work around

Window previews are sometimes shown translucent, for example during
drags or animations. They can also have attached dialogs, in which
case the opacity should affect the combination of all windows instead

Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.
We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.
So just omit braces consistently as mandated by gjs' coding style.
