We're calculating icon sizes for the alt tab switcher early and at a
point where the style attributes of this._list are not loaded yet. To
make sure the value of this._list.spacing is correct, call
ensure_style() on this._list before accessing the spacing.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/587
gjs now supports an optional GTypeFlags value for GObject subclasses
defined with GObject.registerClass(), so it is not possible to define
abstract classes on the gobject-level, just like from C.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/517
Classes that are sub-classes of GObject don't use a constructor per se, so we
can't check for new.target (as this is undefined) in _init.
Then compare the current constructor name instead.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/503
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 commit removes all the uses of Shell.GenericContainer from
SwitcherPopup.SwitcherList. Compared to the other patches, this
one was specially trickier to get right, and a few invasive
changes needed to be done.
The most noticeable one is that the allocation of the items is
done entirely by St.BoxLayout -- we don't manually allocate them
anymore. To make it work, get_preferred_width() had to calculate
the correct value. It now assumes that:
* Minimum width: the minimum width of the widest child.
* Natural width: the minimum width of the StBoxLayout (use it
instead of the natural width to force the labels to ellipsize
when too long.)
The AppIcon class became a St.Widget subclass as well, to override
get_preferred_width() and be able to keep the squared shape.
Besides that, add a new SwitcherButton class to reimplement squared
icons without having to resort to hacks in the size allocation
machinery. This class has a single vfunc override to ensure that it
is squared when the SwitcherList is.
The arrows indicating multiple windows are now in this._list
actor to the SwitcherPopup itself, since this._list automatically
manages its own children now.
At last, adapt (but preserve) the hack in CyclerPopup.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
This commit turns SwitcherPopup.SwitcherPopup into a St.Widget
subclass, and gets rid of Shell.GenericContainer usage. Subclasses
were adapted to that too.
This class introduced a new challenge: it overrides show(). As per
discussions, we now call this.visible = true inside show().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
In the process of purging all usages of Shell.GenericContainer
of GNOME Shell, one specific problematic situation that might
occur is when classes have functions that would clash with any
ClutterActor or StWidget function name.
One of such example is SwitcherPopup.destroy(). Right now, this
class is a pure JavaScript class that wraps a real actor, but
soon this will change, and it'll become a St.Widget subclass.
Another problem with functions that mimic the toolkit ones is
the predictability of them; after calling destroy(), that widget
is expected to not be available anymore. In SwitcherPopup case,
it is still available for a short while. In this case, that's not
a big problem, but the show() and hide() functions in other clases
are more problematic because the actor's visibility does not
follow that.
This commit is a first step in cleaning that up, and changes the
SwitcherPopup.destroy() to fadeAndDestroy().
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
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
Similar to what has been done for the apps switcher, this allows closing
windows pressing W or F4 while operating the windows switcher popup or
the apps switcher popup while navigating the list of windows for an app.
https://bugzilla.gnome.org/show_bug.cgi?id=620106
This will be mainly useful for closing apps from the applications
switcher, but can be implemented generically enough to select the
nearest existing item after removal if there's any, or destroying
the popup's actor otherwise.
Specifically for the apps switcher, doing this also removes the need
of having to manually either update the current app in AppSwitcher
and highlight it, if there are still any items after the removal, or
simply destroy the AppSwitcher otherwise. Besides, calling _select()
in the handler for item-removed makes sure that the list of thumbnails
in the switcher is always closed, if open, when quitting the app.
https://bugzilla.gnome.org/show_bug.cgi?id=620106
Make sure that the items from the applications switcher and the windows
switcher are removed when the related applications get stopped, or some
of the associated windows closed.
https://bugzilla.gnome.org/show_bug.cgi?id=620106
Ensure that key-above-tab for selecting window application is consistent
with the down key.
After focus an application in the switcher:
- if you press down, the window thumbnails are previewed, and first element
is selected
- if you press key-above-tab, the window thumbnails are previewed, however
the second element is directly selected.
Make both interactions always select the first element.
https://bugzilla.gnome.org/show_bug.cgi?id=786009
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.
https://bugzilla.gnome.org/show_bug.cgi?id=785084
Using a MetaWindowActor's shaped texture as the source for window
clones means that if there are further MetaSurfaceActor children
(e.g. a wayland client using sub-surfaces) they don't get cloned.
This obviously wasn't an issue until wayland clients introduced the
possibility of having multiple MetaSurfaceActors under a
MetaWindowActor but there's no fundamental reason we can't clone the
toplevel actor.
WorkspaceThumbnail.WindowClone is the one class that was already using
the MetaWindowActor instead of the texture although it seems to have
been an unintended change in commit
8b99617513.
https://bugzilla.gnome.org/show_bug.cgi?id=756715
Similar to bug 667552 for the app switcher, attached modal dialogs
can result in an unexpected window order in the window switcher:
Selecting a window with an attached dialog will focus the dialog
instead, but as the dialog itself is ignored in the window list,
its last-used timestamp is not taken into account for the position
in the MRU list. Fix this by fetching the list of all NORMAL windows
and filter out skip-taskbar windows ourselves, while making sure that
windows appear in the position of their attached modal dialog where
appropriate.
https://bugzilla.gnome.org/show_bug.cgi?id=747153
Similar to windows on another workspace, selecting a minimized window
doesn't look quite right - the selected window disappears, then animates
back in. Fix this by adding support for skipping the next effect to the
wm and use it to bypass the unminimize animation.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Both 'cycle-group' and 'cycle-window' shortcuts allow cycling through
windows on all workspaces. While this works, it looks quite broken
since we started showing clones for highlighting: the selected window
vanishes (when its clone is destroyed), then slides back in with its
workspace. Instead, slide the selected window to its workspace like
we do for the 'move-to-workspace-*' shortcuts.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Commit 3171819c improved window cycling by using a dedicated to clone
for highlighting rather than activating all cycled windows. Original
window actors are hidden while its clone is showing, and shown again
afterwards, however the latter is wrong for actors that are not supposed
to be visible (for example where the window is minimized, or on a different
workspace). Fix this by properly syncing the actor's visibility instead
of showing it unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Commit bd6e7f14d1 reimplemented the cycle keybindings to
fix cycling between more than two windows, but the approach
of highlighting cycled windows by actually focusing them has
the drawback that cycling messes up the MRU order of windows.
To fix this, only change the window focus when the operation
finishes, and use a dedicated actor that draws a border around
a window clone for highlighting.
https://bugzilla.gnome.org/show_bug.cgi?id=771063
The code to handle cycling through windows without showing a popup
was removed from mutter a while ago, which left the corresponding
keybindings mostly broken (i.e. they now only switch between two
windows). With the various switch-foo keybindings handled by the
shell, it is now easier to take over the cycle-foo keybindings as
well.
https://bugzilla.gnome.org/show_bug.cgi?id=730739
We are currently erroring out when the tab chain doesn't contain at
least one window for an app which might happen for windows that don't
take focus like xeyes. This leaves us in a state where we can't show
the switcher at all. Let's just ignore these apps instead of looking
broken.
We don't really need this step as a separate method since all
implementations are supposed to be created and shown immediately. This
also ensures that we have items to show in all subclasses.
https://bugzilla.gnome.org/show_bug.cgi?id=735976
All derived classes are already checking explicitly for action names
(FOO and FOO_BACKWARDS). mutter used to have a META_KEY_BINDING_REVERSES
flag for keybindings which required special handling of "shift"+FOO as
FOO_BACKWARDS, but this has been removed now, so this special handling
is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
Instead of overriding the actor's request with the icon size, just set
the new icon size on the actors, and let the default handler take the
preferred size of children.
https://bugzilla.gnome.org/show_bug.cgi?id=705410
When restricting the switcher popup to the current workspace, we
filter out running apps with an empty window list (namely: no open
windows on the current workspace). However we may end up with an
empty window list even when not restricting items to the current
workspace when all windows of a running app are associated with a
different application via the transient_for hint.
To fix this, just filter out items with an empty window list
unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=722434
Add an option to limit the appSwitcher to the current workspace. For users
that use workspaces for task separation this more convient then current
behviour. While having to add an option is unfortunate there is no way to make
both groups happy as workspaces usage differes between different users / types
of users.
https://bugzilla.gnome.org/show_bug.cgi?id=703538
Commit 2499f2ed80 went back to using shell_app_activate() for
selecting an app, which favors windows on the current workspace;
this is the behavior we want for instance when activating a
launcher, but it's wrong for the alt-tab list - explicitly
request the first (e.g. MRU) window in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=700356
We chain up on _finish() to drop the grab and destroy the switcher
popup but we should activate the target window first because dropping
the grab results in the previously focused windows getting a focus in
event immediately followed by the focus out event from the target
window activation which we can easily avoid.
https://bugzilla.gnome.org/show_bug.cgi?id=696259
Currently both the app switcher and the thumbnail list divide items
first into two groups (based on whether the item is located on the
current workspace or not), and then sort each group individually
by MRU.
The resulting behavior is often confusing, e.g. when using alt-tab
a second time does not switch back to the original window when the first
invocation involved a workspace switch and the workspace contains
windows of more than one application.
Instead, make the behavior more predictable by sorting both lists
strictly by MRU.
https://bugzilla.gnome.org/show_bug.cgi?id=661156
Now that we use the new 'switch-applications' keybinding for the
application-based alt-tab popup, we can use the 'switch-windows'
keybinding for a more traditional switcher.
Based heavily on the alternate-tab extension from Giovanni Campagna.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
The Shell's alt-tab popup is application-based, so using the
'switch-windows' keybinding for it never really made sense.
Use the newly added 'switch-applications' keybinding instead.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
This hack was part of the custom scroll view code that allowed for
proper scrolling when the actor was near the screen edges. Since
the port to St.ScrollView, it's unnecessary and downright wrong,
causing portions of actors to be clipped. Remove it.
https://bugzilla.gnome.org/show_bug.cgi?id=613194
The appSwitcher has been using a custom scrolling implementation because
St.ScrollView was buggy when it was written. The bugs have been fixed
so remove the custom implementation and move to St.ScrollView.
https://bugzilla.gnome.org/show_bug.cgi?id=613194
The old formula worked only when the primary monitor was positioned at the
top of the virtual desktop. When that was not the case, the available
space was miscalculated sometimes resulting in negative numbers, which in
the end produced strangely vertically stretched window thumbnails.
https://bugzilla.gnome.org/show_bug.cgi?id=651130
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().
https://bugzilla.gnome.org/show_bug.cgi?id=664436
All classes that have at least one other derived class (and thus
benefit from the framework) have been now ported. These includes
NMDevice, SearchProvider, AltTab.SwitcherList, and some other
stuff around.
https://bugzilla.gnome.org/show_bug.cgi?id=664436
Allow push_modal to optionally only work with a keyboard only grab and
use that in altTab as a fallback to allow switching windows while a pointer grab
is in effect (like during DND operations).
https://bugzilla.gnome.org/show_bug.cgi?id=660457
Because we were sorting the Alt+Tab list by user_time rather than
stacking order / MRU, it was possible for the currently-focused window
to sometimes not be the first app in the list. Fix this by using
meta_display_get_tab_list() to get the proper MRU ordering of windows
on the current workspace, and then convert that to an ordered list of
apps.
https://bugzilla.gnome.org/show_bug.cgi?id=645026
js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.
https://bugzilla.gnome.org/show_bug.cgi?id=660358
While we allow for arbitrary modifiers in keybindings, both the
alt-tab and ctrl-alt-tab popups close when ALT is not present in
the modifier mask, resulting in ALT being de-facto hardcoded.
Instead, pass the actual modifier mask when invoking the popups.
https://bugzilla.gnome.org/show_bug.cgi?id=645200
Force an allocation at thumbnails creation so we can figure out whether we
need to scroll when selecting.
We also need to show() the whole AltTabPopup before calling _select() so that,
when computing the scrolling offset, the widgets already have their styles
loaded. Otherwise we will miss the switcher list item container's spacing.
https://bugzilla.gnome.org/show_bug.cgi?id=655069
This patch fixes the "apps vanish from alt-TAB bug".
If a "package system" rips away and possibly replaces .desktop files
at some random time, we have historically used inotify to detect this
and reread state (in a racy way, but...). In GNOME 2, this was
generally not too problematic because the menu widget was totally
separate from the list of windows - and the data they operate on was
disjoint as well.
In GNOME 3 we unify these, and this creates architectural problems
because the windows are tied to the app.
What this patch tries to do is, when rereading the application state,
if we have a running application, we keep that app around instead of
making a new instance. This ensures we preserve any state such as the
set of open windows.
This requires moving the running state into ShellAppSystem. Adjust
callers as necessary, and while we're at it drop the unused "contexts"
stuff.
This is just a somewhat quick band-aid; a REAL fix would require us
having low-level control over application installation. As long as
we're on top of random broken tar+wget wrappers, it will be gross.
A slight future improvement to this patch would add an explicit
"merge" between the old and new data. I think probably we always keep
around the ShellApp corresponding to a given ID, but replace its
GMenuTreeEntry.
https://bugzilla.gnome.org/show_bug.cgi?id=657990
Use a longer fade-in time, but with an inout transition, so that the
dialog starts fading in very slowly and then picks up speed after
150ms or so. That way if the user releases Alt+Tab right away, they'll
never actually see the dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=652346
Remove ShellGlobal's monitor-related methods, and have
Main.layoutManager provide that information instead. Move
Main._relayout() to LayoutManager, and have other objects connect to
the layout manager's 'monitors-changed' signal to know when the screen
geometry has changed.
https://bugzilla.gnome.org/show_bug.cgi?id=636963
AltTabPopup was calling global.stage.get_actor_at_pos() "to force a
stage relayout", but that function does not actually have that effect.
It was also occasionally causing Clutter warnings (possibly due to a
clutter pick-buffer-caching bug?). So just remove the call.
https://bugzilla.gnome.org/show_bug.cgi?id=650317
The initial selection of the Alt+Tab dialog was happening before the
dialog was shown and allocated, and so the "do we need to scroll"
check used bogus coordinates. Fix by showing the dialog (and forcing
an allocation) first.
https://bugzilla.gnome.org/show_bug.cgi?id=647807
Alt+Tab's special case of "switch to the most-recently-used window even if
it's in the same app" is actually an hindrance for users to get a firm mental
model of Alt+Tab. Now that we have Alt+Above_Tab the special case is no longer
needed.
https://bugzilla.gnome.org/show_bug.cgi?id=647907
For applications with no proper desktop file, the window icon is
used as application icon in the tab switcher, but it won't have
the correct icon size. The current approach is to add additional
padding to these icons - the size turns out inconsistent with
other icons, but the icon appears sharp. For the dash it has been
decided that unsharp icons are less evil than differing icon sizes,
so icons are scaled up to the "right" size - for consistency, do the
same in the alt-tab switcher.
https://bugzilla.gnome.org/show_bug.cgi?id=643300
For historical reasons, we had both StClickable and StButton, which
were nearly identical. StButton was more widely-used, so keep that and
port all StClickable users to that.
