The workspace.js file is quite large and is a bit confusing when it
comes to the term "window" in there, because it can either refer to a
WindowPreview of a complete window or to an individual window like an
attached dialog.
So try to avoid that confusion and split the new WindowPreview class and
its WindowPreviewLayout layout manager out into a new windowPreview.js
file.

MetaWindow is Mutters representation of a window and provides all the
APIs about it, MetaWindowActor is just the ClutterActor that's drawing
that window. So use a MetaWindow to create a WindowPreview instead of
the window actor.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
We want to stop using the MetaWindowActor for things which are actually
related to the MetaWindow, one more thing where we can change that is
the overviewHint, which is currently added to the MetaWindowActor.
So move that hint to the MetaWindow and stop calling
get_compositor_private() in a few more places.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
We can simply get the MetaWindowActor by calling
MetaWindow.get_compositor_private(), so stop accessing the realWindow
property of WindowPreview. For this we also have to make _isMyWindow()
and _isOverviewWindow() take a MetaWindow as an argument instead of a
MetaWindowActor.
Since the WorkspacesThumbnails are also drop targets for WindowPreviews
and their WindowClones also have the public metaWindow property, switch
to using the metaWindow property there, too.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
Since the WindowPreview class rarely needs to handle the actual actor
painting the window preview, refactor the WindowPreviewLayout a bit to
only pass a MetaWindow to its addWindow() and removeWindow() functions.
Also make the getWindows() function return an array of MetaWindows,
which makes the getMetaWindow() function obsolete, so remove that.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
We're going to remove ClutterClones, so call the parameters to
addWindow() and removeWindow() "actor" instead of "clone". Also make the
destroyIds less confusing and rename the actual actor destroy id to
"destroyId", and rename the window actors destroy id to
"windowActorDestroyId".
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
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.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
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.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1313
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
to the wrong pointer.

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.
