Adding children to the WorkspaceLayout without calling addPreview() is
not supported, so let's log an error in case that happened.
We also have to allocate that child an empty ClutterActorBox, otherwise
Clutter will complain loudly.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1481>
Clutter expects actors overriding the allocate vfunc to allocate all
mapped children of the actor, otherwise bad things happen.
So make sure we actually allocate all our visible children in our custom
allocation functions, and since we don't want to give them a real
allocation, just pass them an empty ClutterActorBox.
It would be nice if we had a way to hide children during the allocation
process where no relayout is queued like gtk allows with
gtk_widget_set_child_visible(), then we could avoid those weird empty
ClutterActorBoxes.

A window preview's floating geometry is scaled down according to the
workspace's allocation, while the layout geometry is computed directly
for the available space.
For previews that maintain their real size in the layout geometry,
that scaling leads to a distracting size bounce when transitioning
between both layouts.
Address that by not allowing the scaled floating size to drop below
that layout size (which is at most equal to the unscaled floating size).
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2968
When using the fade animation when transitioning to the overview instead
of zoom, we fade out all window previews to fully transparent. But after
commit 751189253a removed the old _updateWindowPositions() function,
nothing resets the opacity again, so when switching from the app- to the
window picker, all previews are hidden.
Fix this by always resetting the window preview opacity after showing
or hiding the overview.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
We don't animate size and position when fading, so we want all previews
to already be at their final position. However when the app picker is
opened from within the overview, window previews use the zoomed layout,
so that's the state we are then fading when leaving the overview from
the app picker.
Fix that by setting the correct state at the start of the fade transition.
(In the case of fadeToOverview(), the value should always be correct
already, but set it anyway for symmetry with fadeFromOverview())
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
It doesn't matter which animation we use to enter the overview,
we always want to start and end with the floating layout.
The simplest way to achieve that is by creating the state adjustment
with the correct value in the first place.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1353
The transition was temporarily removed when switching to the new
workspace layout manager. Now everything is in place to reimplement
it with a combination of the layout manager's state adjustment and
the view's allocation.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1345
Switch to the new WorkspaceLayout layout manager to allocate the window
clones of the overview properly using Clutters layouting mechanisms.
Since we now no longer make use of the fullGeometry, we can remove the
setFullGeometry() function from the Workspace class. Also we can stop
setting the actualGeometry on the Workspaces and WorkspaceViews and
instead just set the fixed position and size of the views to their
full or actual geometry. This also has the benefit that we no longer
have to set a custom clip, but can simply enable clip_to_allocation.
The geometry needs to be set inside a BEFORE_REDRAW later because
_updateWorkspacesActualGeometry() is called from a notify::allocation
handler.
This isn't doing any animations when showing/hiding the overview yet,
we'll add that in the next commit.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1305
Add a new ClutterLayoutManager for layouting the workspaces of the
overview, WorkspaceLayout.
This layout manager integrates the existing LayoutStrategies used to
layout the window clones of the overview and supports freezing the
layout, animating between layout changes and adjusting the spacing for
the width and height of the window chrome. It also adds support for a
layout of the windows that looks the same as the actual workspace,
transitioning between that layout and the LayoutStrategy can be done by
setting the value of an StAdjustment, available using the
stateAdjustment getter function.
This will replace the current static-positioning based layouting of the
window clones in the next commit.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1305
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.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
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
