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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=640583
When aiming for the thumbnails with the mouse one might cross an
icon by accident which causes the thumbnail list to be closed, which is
frustrating.
Fix this by delaying the icon activation when the thumbnail list is
open.
https://bugzilla.gnome.org/show_bug.cgi?id=636650
If the switcher is destroyed without ever being fully shown (either
because it couldn't get a keyboard grab, or just because there are no
apps to display), destroy it immediately rather than tweening it
towards destruction, since its contents haven't been built yet and
_allocate() will throw errors if it runs.
This makes it consistent with other parts of the UI and will let the
a11y code use the rule "has_style_pseudo_class('selected') =>
ATK_STATE_SELECTED"
https://bugzilla.gnome.org/show_bug.cgi?id=637830
Until recently, the clutter keyboard focus was almost always kept on
the stage, and bits of code that wanted to do stuff with the keyboard
would just watch for key-press-events on the stage. In several places,
the code wasn't even bothering to ensure that the focus was on the
stage, which caused problems with other actors that explicitly grabbed
focus.
A previous fix for this (f21403fd) was to always reset the focus to
the stage after calling pushModal(), but a better fix is to just
actually make use of the keyboard focus everywhere rather than having
everyone try to read events off the stage.
Now pushModal(actor) also does actor.grab_key_focus(), and various
bits of code have been changed to read key events off their own
toplevels rather than off the stage, meaning there's no chance of them
accidentally getting someone else's events.
https://bugzilla.gnome.org/show_bug.cgi?id=618885
Although within St itself there are situations where the semantics of
these functions (return TRUE or FALSE and return the actual value in
an out parameter) is useful, it's mostly just annoying at the
application level, where you generally know that the CSS property is
going to specified, and there is no especially sane fallback if it's
not.
So rename the current methods to lookup_color, lookup_double, and
lookup_length, and add new get_color, get_double, and get_length
methods that don't take an "inherit" parameter, and return their
values directly. (Well, except for get_color, due to the lack of (out
caller-allocates) in gjs.)
And update the code to use either the old or new methods as appropriate.
https://bugzilla.gnome.org/show_bug.cgi?id=632590
The keyReleaseEvent handler does not take into account that a
user might release Alt while still holding shift
(the keycode becomes Meta_L/R in that case).
The result is that the switcher stays open which is unexpected.
https://bugzilla.gnome.org/show_bug.cgi?id=629368
In Clutter 1.2, clutter_event_get_keysym() ignored the state of the
Shift key. In 1.4, it does not, so we have to adjust our comparisons
accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=627782
The design calls for item to not appear abruptly, but not too slow
either - 100ms seems to be a good sweet spot for elements which are
supposed to appear "instantly".
Add a fade effect to the alt-tab popup and set the timings for other
fade effects to 100ms.
https://bugzilla.gnome.org/show_bug.cgi?id=621247
SwitcherList.actor is no longer a St.BoxLayout but a
GenericContainer now, so the hack in AppSwitcher._getPreferredHeight is no
longer needed (it is called with the correct width now).
https://bugzilla.gnome.org/show_bug.cgi?id=613194
Per design discussion, change things back so that when choosing
an individual window, we raise only that window. However
when we select an application, raise all windows.
A behavioral change required to clearly differentiate these
is that when the window thumbnail list is popped up, it no
longer has the first window selected by default. Therefore
the user has to explicitly press the down arrow or use the
mouse to enter individual window selection mode.
https://bugzilla.gnome.org/show_bug.cgi?id=617959
This is our convention.
The only exceptions are double quotes for words in comments that give
them a special meaning (though beware that these quotes are not truly
necessary most of the time) and double quotes that need to be a part
of the output string.
In preparation for adding magnification, "uiGroup.patch", organizes the stage
along the following lines:
Stage
*Magnifier
UI group
Window group
Chrome group
Overlay group
Alt tab
App display
Chrome
...
This allows a magnifier actor to clone and magnify the UI group. The magnifier
is a sibling of the UI Group in this stage oraganization -- see the next patch,
"Magnifier.patch".
We can't use gdk_display_get_pointer/gdk_window_get_pointer from gjs
when XKB is active. We already had a wrapper that did the
get-modifier-state part of that, but some places also need the
get-pointer-location part of it. So update our wrapper to return both,
and update js code to use it.
https://bugzilla.gnome.org/show_bug.cgi?id=613428
The POPUP_LIST_SPACING constant was used for the AltTabPopup.actor's padding,
AltTabPopup.actor's spacing and SwitcherList._list's spacing.
Switch to CSS and remove the constant.
https://bugzilla.gnome.org/show_bug.cgi?id=613195
Limit the AppSwitcher to the screen size by either downscaling or
scrolling.
We scale the icons down up from 96, 64, 48, 32 to 22 and start scrolling
if we still fail to fit on screen.
The thumbnail box is shifted to either left or right, when failing to
fit we scroll here to.
To prevent from being offscreen at the buttom we adjust the thumbnail
height to fit.
The old positioning logic is replaced with a ShellGenericContainer to
implement a custom allocation system.
