Since ClutterClones are going to be removed, let's switch the
terminology here to something that's more understandable and rename the
WindowClone class and its layout manager to
WindowPreview/WindowPreviewLayout.

Using CSS to center the title actor on the border is a bit ugly, because
it requires the CSS to match the calculations used in chromeHeights().
Also it is not possible to use CSS margins for cases where the position
of the actor is determined at run time, such as for the close button.
Instead use an invisible actor that spans between the horizontal and
vertical center lines of the border as guide when aligning the title
actor.

Commit 1ea22a5281 broke the window reposition animation when it
based the ::size-changed signal on the layout manager's bounding box
instead of the MetaWindow::size-changed signal.
That's happening because of the combination of:
1. we adjust to window size changes immediately without animations
2. closing a window triggers a change to a 0x0 bounding box which
is not treated as a size change
Fix this by addressing the 2nd factor, and don't treat a change to
a 0x0 bounding box as size change.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2901
Start using the new overlays we introduced in the last commit and remove
the WindowOverlay class and the objects for keeping track of them in the
Workspace.
The new layout which doesn't use the -shell-close-overlap CSS property
anymore sligthly changes the position of the close button to be a bit
further away from the actual window.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1298
So far we allowed the titles of window overlays to expand their width to
be larger than the actual WindowClone, they could expand to the full
size of the Workspace.
Since we're now going to implement those titles as part of the
WindowClone itself, having this feature is no longer possible as easily
as it was before. That's because the clones are stacked according to the
stacking of the actual windows, and since the overlay-elements are
attached to those clones, they will also be shown underneath other
clones.
So stop allowing the titles to expand and limit their size to the width
of the clone, which makes sure titles never get shown above or
underneath other clones.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1298
Add the window overlays we're currently showing using the WindowOverlay
class to the WindowClone class and implement them using
ClutterConstraints instead of the old fixed position/size layout, which
had to be used because the workspaces were scaled, and the title and app
icon were kept unscaled using a separate layer.
Specifically, this is done by adding the ClutterClones to a static
container owned by the WindowClone and adding the elements of the
overlay as children to the WindowClone itself. That way the
overlay-elements can use the container as a source for their constraints
and we avoid having to make sure the overlays remain visible above the
ClutterClones.
We're not using the new overlays yet, they're hidden by default and
showOverlay() isn't called anywhere yet.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1298
Now that we have a new API to get all the windows and metaWindows from
our layout manager, implement the deleteAll() method of the window clone
using that API instead of looping through the children of the actor and
using the source of the ClutterClone.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1298
This comment is no longer correct, we're not inserting any actors here
to adjust for the window border, but we're modifying the allocation of
the children to adjust for that border.
Since that happens in the layout manager anyway, remove the comment
here.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Now that we handle all ClutterClones belonging to the WindowClone pretty
much the same, we can add a generic _addWindow function to WindowClone
which creates the ClutterClone and adds it to the layout manager.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
This isn't quite the same as the allocation, but it's what the workspace
actually wants to use given that we use the bounding box of the
WindowClone for all the layout calculation.
So instead of calculating the windowCenter in the WindowClone, make use
of the bounding-box property of the layout manager and return the center
point of that.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Make use of the new bounding-box property we introduced for the
WindowClones layout manager in the last commit.
With this we can remove all the bounding box calculation code from the
WindowClone class and simply use the "notify::bounding-box" signal to
notify changes to our size. To make sure users of the WindowClone don't
break, we now have to convert the layout managers ClutterActorBox in our
getter function to a JS object.
Since we now also don't have to connect to the "destroy" signal of the
attached dialogs anymore, we can remove _disconnectSignals() and only
listen to "destroy" of the toplevel window.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Move the tracking of the bounding box and all the layout related things
out of the WindowClone class and into the layout manager. This allows
the layout manager to keep track of its windows itself and simply notify
the new bounding-box property in case that box changes.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
Since we now have a layout manager for the WindowClone that allows
allocating it a size that isn't the absolute size of the window, we can
now give the WindowClone an artificial size and it will get scaled
accordingly.
So make use of that and stop positioning WindowClones using fixed
position and scale and use a fixed position and fixed size instead. This
will make it easier to use a ClutterLayoutManager to allocate the
WindowClones, because layout managers should only set the allocation of
their children, not the scale.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
Since we're going to override the fixed width and height of the
ClutterActor the WindowClone is subclassing, remove those confusing
getter methods for width and height and switch to the public boundingBox
for getting that information.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
The getOriginalPosition() API of WindowClone can easily be replaced by
using the existing boundingBox property, which reflects the windows
bounding box in absolute coordinates. This property is also used
everywhere else in the Workspace object, so we can use it here, too.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
Change the preferred size functions of the layout manager of window
clones to allow allocating smaller sizes, too. Also scale down the
allocation sizes of the ClutterClones our allocate implementation so
the ClutterClones will scale their texture accordingly.
This will enable us to position the window clones using their allocation
size instead of their scale, which is necessary when introducing a new
ClutterLayoutManager that positions the window clones.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
We're going to add a ClutterLayoutManager responsible for allocating the
WindowClones. Since layout managers should only set the allocation of
actors, not the translation or scale, we need to position the
WindowClones using their x, y, width and height properties.
The first step for this is to revert this commit, which switched from
setting fixed positions on WindowClones to using the translation
properties.
This reverts commit 8929c89d1f.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1294
As explained in the comment in _init() of WindowClone, we hide the
actual clone from picking so it doesn't interfere with XDND.
This description applies to the clones of the attached dialogs just as
well though, so hide the clones of attached dialogs from picking, too.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1293
Commit 55b57421d changed signal handlers to the corresponding vfuncs,
but didn't always chain up as necessary. In most places this doesn't
matter, but at the very least the commit broke activating message list
items via the keyboard.
Add all (hopefully) the missing chain-ups to get the expected behavior
back.

Make sure the stylesheet properties of the window-chrome title are
updated before requesting the preferred width of the title to prevent
size changes of the title after we animated the width.

This is necessary to make DnD operations work from tablet devices on
wayland, as it's not the same onscreen pointer sprite than mice. Fixes
window DnD in the overview on tablet devices, no longer having them stick

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
When accessing properties on ClutterActor for size and position there is
a notable access time overhead. This overhead adds considerable user lag
when opening the overview if many windows are open.
This is primarily due to these properties being accessed while sorting
WindowClone instances by their window's center for placement in the
overview. By pre-computing this center value only once when
initializing WindowClone, the induced lag can be significantly reduced.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/763
Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

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()`.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/735
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
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
window clone would get animated back to their original position
(indicating that nothing happened) even though they opened correctly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/121
`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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/121
Instead of returning and waiting until the old timeout is finished,
start a new idle hide timeout for the overlay when the pointer enters a
window clone. This makes sure the timeout for hiding the overlay after
the pointer left the clone mostly stays the same (except when leaving
the clone via the title or the close button).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/683
Code and comment were based on the old get_input_rect() and get_outer_rect()
method names that were changed to the more appropriate get_buffer_rect() and
get_frame_rect() a long time ago.

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.

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
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
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
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
of being applied to each window individually, blended together, so
make sure they are redirected as a whole when necessary.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/774
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.

We can use that newer method where we don't care about the actual position
of an element inside the array.
(Array.includes() and Array.indexOf() do behave differently in edge cases,
for example in the handling of NaN, but those don't matter to us)
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/152
Since version 1.50.0, gjs defines GObject.NotImplementedError for throwing
errors when a "virtual" method that requires a subclass implementation is not
defined.
So use this instead of a generic JS Error in such cases.

Since the overlays we show on hover above the window clones are no
longer only a close button, but the window title, a border and a close
button, rename a few variables so it's easier to understand what they're

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any

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
allow the captions to leak outside the workspace area itself and
overlap unrelated elements like workspace switcher or dash.
This partly reverts commit b3b30f239d.

When trying to close a window in the overview by clicking the close
button and the window doesn't get closed but a dialog is added to the
window afterwards, we close the overview and show the dialog.
Instead of adding a separate listener for the window-added signal to the
WindowOverlay, let the WindowClones remember that the close button was
pressed and activate themselves if a dialog is added after that.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/180
When a dialog is added to a window while the overview is shown, we get
its parent using get_transient_for() so we can add it to the right
window clone.
If we have multiple layers of dialogs we have to do this recursively
until we find the root ancestor. This case currently results in an
infinite loop: Since parent is always set to the same window, the
while-condition will always be true.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/180
If a clone gets destroyed before the corresponding MetaWindow is
removed from the workspace, we will still find it in the list of
clones and try to destroy it again. Avoid the resulting warnings
by updating the list of clones immediately when a clone is destroyed.

Remove any usage of MetaScreen, as it has been removed from libmutter

Just like we did for the window list in app icons' context menu,
provide a fallback for window captions in the window picker rather
than showing blank items to the user.

Since commit 1939e22c22, we move the keyboard focus with the hover
highlight. However while this makes sense when interacting with
the window picker, it interferes with keyboard navigation of other
components like dash or top bar. Address this by only moving the
focus when the previous focus was already inside the window picker
or unset.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.
