At the point it is disabled, it has got signal handlers connected but

Now that the existing touch/touchpad gestures in windowManager only
handle normal mode, add corresponding gestures for the overview and
hook them up to the existing workspace scroll animations.

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

This attribute was previously only assigned in show(). hide() compares
this attribute to 0. If hide() is called before show() is first called,
the comparison would give the correct result (undefined > 0 is false)
but log a warning:
JS WARNING: [resource:///org/gnome/shell/ui/workspacesView.js 529]:
reference to undefined property "_restackedNotifyId"
Initialize this attribute in _init(), alongside _scrollEventId and
_keyPressEventId which are also used in hide().
Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

It is odd to switch workspaces on the primary monitor when panning on
a monitor without workspaces, so reject the gesture on non-primary
monitors when workspaces-only-on-primary is disabled.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
It is odd to switch workspaces using the scroll wheel when the pointer
is on a monitor without workspaces, so only handle scroll events on
non-primary monitors when workspaces-only-on-primary is disabled.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
We allow activating a workspace by clicking it when we know that
the user did not try to select a window and missed (namely: the
workspace is empty). However we currently always check for an
empty workspace on the primary monitor, which doesn't make sense
when the click happened on a different monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
Initializing the upper bound to zero means that on panning we'd start
scrolling from the first workspace even if the current workspace when
entering the overview was different since StAdjustment clamps the
value to be inside bounds.
https://bugzilla.gnome.org/show_bug.cgi?id=766883
This works for pointers and touch on X11, there is however no pointer
emulation on evdev, so touch triggers ::clicked with button==0 which
is ignored.
https://bugzilla.gnome.org/show_bug.cgi?id=756748
To switch workspace by keyboard in the overview, the user currently
has to use the normal keybinding. However as the vertical alignment
of workspaces makes them very similar to pages in the app picker, it
makes sense to also support the standard pageUp/pageDown keys.
https://bugzilla.gnome.org/show_bug.cgi?id=742581
It is quite weird to have those calls/signals using WindowClone as an
argument, it is neater to pass MetaWindows around, and have each user
deal with their own representations of these.
https://bugzilla.gnome.org/show_bug.cgi?id=735972
And use it to lookup the local WindowClone that applies. Otherwise,
WorkspaceThumbnail.WindowClone objects may be mistakenly set, which
are not usable interchangeably with Workspace.WindowClone ones. This
may lead to several misbehaviors as fields available in the second
object but not in the first one are accessed, some those undefined
values get used in math ops, which result in NaNs over the place.
Likewise, the similar functions in WorkspacesViewBase subclasses take
now MetaWindow arguments too.
https://bugzilla.gnome.org/show_bug.cgi?id=735972
The zooming animation of the windows looks nice when animating
from the workspace display page, but looks weird from other pages
like apps page or search page since the windows come from nowhere
with an initial position not known to the user.
Instead of that just fade the desktop with the windows in its
original position.
https://bugzilla.gnome.org/show_bug.cgi?id=732901
They are different properties, they deserve different syncs.
Especially because a full allocation cycle sets both anyway, so
we should save some cycles this way.
https://bugzilla.gnome.org/show_bug.cgi?id=729823
By default, gesture actions no longer wait for the dnd threshold to
be reached before triggering, which breaks our mixing of click- and
pan actions. Fix this by only panning after reaching the threshold
and letting the click action go through if the pan is cancelled.

Workspaces can removed from any index, and in particular they
will be removed by the WorkspaceTracker if they stop containing
windows at some point. Make sure WorkspacesView is not confused
and destroyes the right Workspace objects.
https://bugzilla.gnome.org/show_bug.cgi?id=721417
Simply use St's existing key navigation system by making all the window
clones StWidgets, and making the WorkspacesView a focus group.
Since the workspace view is effectively "fake", we need to add a focus
delegator so that when key focus is assigned to the fake workspaces page,
we can keynav inside it properly.
https://bugzilla.gnome.org/show_bug.cgi?id=644306
Before, workspacesOnlyOnPrimary was implemented in quite a crazy manner:
* If workspacesOnlyOnPrimary was false, we'd create one WorkspacesView per
monitor, with the primary one being a bit special.
* If workspacesOnlyOnPrimary was true, we'd create one WorkspacesView, and
additional montiors would be handled inside that WorkspacesView as
"extra workspaces".
This caused numerous bugs as the two modes weren't consistently
implemented, and a lot of code was duplicated between all the modes.
Fix this by always creating WorkspaceViews, even if it only handles
one interface. We do this by having two different WorkspacesView-ish
classes: WorkspacesView handles the traditional combination of lots
of workspces, and a new ExtraWorkspaceView is in control of only one
workspace.
Right now, the workspace update code is complex and spread across parts:
WorkspacesView takes a set of workspaces and looks like it owns them, but
WorkspacesDisplay is actually in charge of setting them up and creating
new ones for each WorkspacesView.
Change initialization and handling to move all of the creation/destruction
responsibilities to WorkspacesView.
We pass in monitorIndex into each WorkspacesView, which is a lie in the
workspacesOnlyOnPrimary case, as the primary WorkspacesView currently has
the responsibility of handling the extra workspaces on all the other
monitors. The commit will clean this up and punt the responsibility back
to WorkspacesDisplay.
Commit 16fa186b63 attempted to fix the zoom animation problem
by throwing changes on the floor while the overview is animating. This has
the side effect that we might end up missing some positioning changes causes
windows to overlap the workspace thumbnails.
So revert those changes and fix it by simply by passing
WindowPositionFlags.ANIMATE during the overview animation.
This way the animation works as expected and we don't miss any position changes.
https://bugzilla.gnome.org/show_bug.cgi?id=703105
When the allocation of the workspacesView changes during the animation we override
the tween with one that does not animate causing the overview zoom animation
not to happen.
Fix that by ignoring the alloactionChanged notification during the overview
animation.
If we created a workspace after showing the view, we would never
set the geometry on it, which would cause an exception in the
window layout code and leave the DND state tracking in an undefined
state.
https://bugzilla.gnome.org/show_bug.cgi?id=699029
Instead of doing an entire recalculation of window positions when
sliding the thumbnails box, simply recalculate the position and scale
with basic aspect ratio math. This also ensures that windows won't
miraculously swap positions, even if we reposition windows while the
thumbnails box is expanded.
https://bugzilla.gnome.org/show_bug.cgi?id=694469
As we want to eventually track two geometries, we need to rename
our very plain "_x, _y, _width, _height". While we could just prefix
them, I think that stuffing them in an object makes more sense.
At the same time, make the variable and method name more descriptive
by adding such a prefix, as well as a bit of documentation.
https://bugzilla.gnome.org/show_bug.cgi?id=694469
To ensure that we don't recalculate window layouts when zooming
in or out, we need to always pass the full geometry. This will
break window repositioning when we zoom back in; for the purposes
of commit clarity, this breaks this feature for now. It will be
added back soon.
https://bugzilla.gnome.org/show_bug.cgi?id=694469
DND of windows has a lot of side effects, including the possibility of
current workspace disappering from under our feet. We need to account
for that when trying to activate it.
https://bugzilla.gnome.org/show_bug.cgi?id=685285
When a swipe scroll completes, we scroll the active workspace into
view. This works fine if the gesture is completed properly by
emitting 'gesture-end', but not when Clutter considers the gesture
cancelled - in that case, the view remains stuck in an intermediate
position. To fix, treat 'gesture-cancel' the same as 'gesture-end'.
https://bugzilla.gnome.org/show_bug.cgi?id=689394
Both WorkspacesDisplay and ThumbnailsBox need to know when windows have been
restacked. Instead of each tracking changes on their own or trying to call
each other, have the overview keep track and do the calculations, emitting
a signal with the result.
https://bugzilla.gnome.org/show_bug.cgi?id=690175
The thumbnail controls are not a separate actor in the overview group
yet, so we need to ensure a spacing between them and the workspaces
view.
Instead of exporting the overview spacing, just add a temporary style
class to the workspaces-view actor for it. It will be removed in the
future when we change the layout of overview elements.
https://bugzilla.gnome.org/show_bug.cgi?id=690174
On additional monitors the workspacesView takes up the entire monitor
and in some cases windows in overview can end up hard against the
edge of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=688133
Ouch. This went unnoticed for a long time as by default (using
dynamic workspaces) only one workspace is added at a time, which
happens to work fine.
https://bugzilla.gnome.org/show_bug.cgi?id=686487
Hide workspace switcher if dynamic workspaces is disabled and number of
workspaces is set to one only, since the user is bound to only one workspace
and showing the switcher is redundant.
Signed-off-by: Seif Lotfy <seif@lotfy.com>
Currently we animate scrolling to the active workspace both when
the number of workspaces changed and after changing the active
workspace. So in case we don't actually change workspace, this
results in an unnecessary animation that may even have unwanted
side effects: when done during the overview transition (e.g. in
the case of opening and activating a window on an empty workspace),
non-active workspaces become visible during the transition.
To fix, don't scroll to the active workspace when the number of
workspaces changes and rely on the 'switch-workspace' signal being
emitted as necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=682002
Most of code implementing workspace switches was repeated with
minor differences on each direction. Instead, consolidate it
and use the new meta_workspace_get_neighbor.
https://bugzilla.gnome.org/show_bug.cgi?id=674104
Currently we only connect to the 'notify::n-workspaces' signal the
first time the overview is shown, which means we will miss any
changes to the workspace layout in the meanwhile.
In particular, the decision of whether the workspace switcher should be
shown is taken before the dynamic workspace handling takes over, and is
thus based entirely on the value of the num-workspaces user preference
rather than the actual number of workspaces.
Just connect the signal in _init() (with the nice side-effect to make it
explicit that the signal handler won't ever be disconnected).
https://bugzilla.gnome.org/show_bug.cgi?id=673198
We seem to have a lot of code that does something along the lines of:
if (condition)
actor.show();
else
actor.hide();
ClutterActor already has such a thing for exactly this purpose: the 'visible'
property. Use it instead of the mess above.
https://bugzilla.gnome.org/show_bug.cgi?id=672272
If the user has their mouse over the workspace thumbnails while
entering the overview, it's more likely that it's a coincidence
that their mouse pointer is in the area. Avoid expanding the
thumbnails box in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=651092
When in overview, window labels flicker or are temporarily hidden on a
number of occasions - when simply clicking around the area the windows
are displayed in, dragging a window, sliding in the workspace list,
adding new workspaces etc. This patch makes the label for any window
visible at any given moment when in overview and the said window is
not being dragged around.
https://bugzilla.gnome.org/show_bug.cgi?id=644861
If workspaces-only-on-primary is false, swipe scrolling is now
broken with multiple monitors. To fix, let workspacesDisplay
handle swipe scrolling for all views.
https://bugzilla.gnome.org/show_bug.cgi?id=652580
If workspaces-only-on-primary is false, workspaces should be shown
on each monitor; rather than letting the existing workspaces span
the entire screen, manage one workspacesView per monitor (similar
to the extra workspaces in WorkspacesView when the setting is true).
https://bugzilla.gnome.org/show_bug.cgi?id=652580
Extra workspaces are special, in that they collect windows from
all workspaces for a particular monitor. This matches the default
behavior, but we need more than a single workspace per monitor if
workspaces-only-on-primary is false, so don't create the extra
workspaces in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=652580
WorkspacesDisplay was introduced to manage the workspace objects
and views; however, the overview still accesses the view held
by the workspacesDisplay directly, which is a bit odd.
Add some additional methods needed by the overview, and make the
view a private property.
https://bugzilla.gnome.org/show_bug.cgi?id=652580
The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().
