The event blocker is an actor that is added in between the
icon grid and the app folder popup in order to guarantee
that clicking outside the app folder will collapse it.
However, the next patch will require allowing dragging events
to be passed to folder icons, and the event blocker gets in
our way here, preventing drag n' drop to work properly.
Add an API to inhibit the event blocker. This API will be
used by the app folders while an item is dragged.

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;
if they were ever actually required at all, this is no longer the case
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.

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.

The functionality the searchResultsBin container provides can easily be
